The Natural History Museum’s new temporary exhibition, Space: Could Life Exist Beyond Earth?, is an exercise in carefully calibrated wonder. It arrives at a time when space stories are no longer the sole province of headline-making missions and sci-fi fantasies: real samples from asteroids and increasingly sophisticated telescopes have made the question of life beyond Earth scientifically urgent and culturally resonant. The NHM has framed that urgency into a compact, visitor-focused experience that manages to be accessible to families while still rooted in contemporary research. The exhibition runs in the Waterhouse Gallery and is on display through 22 February 2026. Below I’ll take you through the exhibition’s structure, objects and interactive features, its strengths and small missteps, and who I think will get most out of a visit.

Upon entering the Waterhouse Gallery, you gain a sense that the museum has deliberately dimmed the world outside. The gallery lighting and sound are calibrated to create a theatre-like focus: illuminated specimens, glowing installation pieces, and pockets of darkness that let projection and light-based exhibits sing (as illustrated in my photo above). A massive globe motif and clustered circular projections set up the exhibition’s two interlocking themes from the start, the micro and the macro: how life begins from chemistry and geology, and how those beginnings might repeat elsewhere across the cosmos. This is not a shrine to rockets show. Instead, the design emphasises environments such as Earth’s extreme niches, asteroids, Mars, icy moons, and the far-off exoplanets, and invites you to compare them. The layout is mostly chronological/planetary which starts on Earth, moves out to the moon, then Mars and the asteroids belt, before swinging by the icy moons within our solar system, and finishing with exoplanets and the big question of detectability. The circulation feels intuitive and never forces you to backtrack, which is a relief in a gallery that packs a lot into a relatively modest footprint. Of course, you are free to do so if you wish.

When life first emerged on Earth, the planet was home only to simple microbial organisms, far removed from the complex plants and animals we know today. These earliest life forms were likely single-celled microbes resembling modern bacteria and archaea, thriving in environments such as shallow oceans, volcanic hot springs, and deep-sea hydrothermal vents. They lacked nuclei, internal structures, and specialised tissues, relying instead on straightforward chemical processes to survive, absorbing nutrients directly from their surroundings and using primitive metabolic pathways to generate energy. Some of these early microbes may have carried out anaerobic metabolism, flourishing in an atmosphere with little to no oxygen, while others harnessed chemical energy from minerals in the crust. Over hundreds of millions of years, these simple cells diversified, eventually giving rise to photosynthetic organisms that transformed Earth’s atmosphere and paved the way for more complex life. How did this life form and what can that tell us about our own origins as well as the potential for other life in the solar system?

One of the exhibition’s standout moments (in my mind) is the chance to touch a real meteorite, a piece of ancient space rock that predates Earth itself. This tactile object is often an Allende-type carbonaceous chondrite, a meteorite formed over 4.5 billion years ago, containing some of the oldest solid materials in the Solar System. Its dark, speckled surface feels surprisingly smooth and cool to the touch, a physical reminder that you are laying your hand on matter that drifted through space long before our planet finished forming. For many visitors, this is the moment when the cosmic timeline becomes real: the idea that life’s essential ingredients may have been delivered to Earth by objects just like this becomes suddenly, viscerally believable. The exhibition uses this touchable meteorite not just as a novelty but as a storytelling anchor. It’s positioned to help visitors understand how meteorites carry organic compounds, minerals, and water-bearing materials, making them crucial to theories about life’s origins. It’s location towards the beginning of the exhibition helps carry this message throughout the rest of the narrative. Paired with mission samples and digital displays about asteroids like Bennu and Ryugu, the meteorite becomes a bridge between past and present — between the early Solar System’s chaotic chemistry and today’s high-tech efforts to study similar objects up close. In a show full of immersive visuals and interactive models, this simple act of touching a rock from space might be the most powerful, grounding encounter of all.

The Estherville meteorite is one of the most remarkable extra-terrestrial objects ever to fall on Earth, known especially for its dramatic witnessed fall near Estherville, in Emmet County, Iowa, on 10 May 1879. As it streaked through the afternoon sky, eyewitnesses reported a brilliant fireball and thunderous detonations before the object broke apart and crashed into the ground in several large pieces, scattering smaller fragments across the surrounding countryside. The event was so powerful that it shook the earth and startled local residents, making it an unforgettable moment in American meteoritic history. Scientifically, Estherville is classified as a mesosiderite-A3/4, a rare type of stony-iron meteorite composed of roughly equal parts silicate rock and nickel-iron metal, believed to have formed through violent impact mixing on an ancient asteroid. Its complex internal structure includes minerals such as olivine, pyroxene, and plagioclase in a metal matrix, offering valuable clues about early Solar System processes. Isotopic studies indicate that parts of the meteorite crystallised more than 4.4 billion years ago, making it a priceless record of planetary formation. Fragments of the Estherville meteorite are housed in museums around the world, including the Smithsonian and the Natural History Museum in Vienna, and smaller pieces continue to be studied for their scientific insights. Some of this amazing meteorite is on display within the exhibition (as photographed below) with signage informing visitors of its story.

All of this makes visitors ponder the abiogenesis, the natural process by which life arises from non-living matter. Rather than imagining a single sudden event, scientists view abiogenesis as a gradual transition: simple molecules forming in early Earth’s oceans, volcanic environments, or hydrothermal vents; those molecules linking into more complex organic compounds, and eventually, self-replicating chemical systems emerging. Conditions on early Earth (abundant energy from sunlight, lightning, and geothermal heat, combined with water and a rich chemical environment) created a planetary laboratory where amino acids, nucleotides, and sugars could form. Experiments such as the famous Miller–Urey study demonstrated that, under early Earth–like conditions, organic building blocks can spontaneously arise. Over millions of years, these building blocks assembled into protocells, giving rise to the earliest microbial life. If it could happen here, could it or did it happen elsewhere?

Materials delivered from space may have played a crucial supporting role in this process. Meteorites and comets carry a surprising variety of organic molecules, including amino acids, carbon compounds, and even water trapped within minerals. Carbonaceous chondrite meteorites (some of the oldest objects in the Solar System) contain complex chemistry that predates Earth itself, offering a ready-made supply of the ingredients needed for life. Frequent impacts during Earth’s early history could have delivered these materials to the surface, enriching the planet’s chemical inventory and jump-starting prebiotic reactions. This cosmic contribution doesn’t diminish Earth’s own chemistry, instead, it complements it, suggesting that the building blocks of life may be widespread in the universe. If life began with a blend of terrestrial and extra-terrestrial ingredients here, it raises a profound possibility that similar processes could unfold on other worlds as well.

The second the most memorable moment in the exhibition is the chance to touch a real piece of the Moon, a rare opportunity that instantly collapses the distance between everyday life and the wider cosmos. Lunar meteorites like this one are fragments of the Moon’s surface that were blasted into space by asteroid impacts millions of years ago. After drifting through the Solar System, a tiny number eventually fell to Earth, where scientists identified them by their unique chemistry and mineral structure. The sample on display is cool, smooth, and unexpectedly subtle in appearance, yet it represents a world we’ve only ever visited six times. To place your hand on it is to make direct contact with material shaped by ancient volcanic flows, micrometeorite impacts, and the silent vacuum of space. This touchable Moon rock serves as a powerful educational anchor, connecting visitors to the story of how we study the lunar surface even when we aren’t sending astronauts there. The simple act of touch communicates an idea far more compelling than any graphic or video could: that the Moon is not just something we see in the sky, but a place made of real, ancient rock, and a world that continues to share pieces of itself with Earth.

Before we go any further, it is worth clearing something up. Asteroids and meteorites are related, but they refer to very different stages of the same kinds of objects. Asteroids are rocky or metallic bodies that orbit the Sun, mostly found in the asteroid belt between Mars and Jupiter, though many also exist throughout the Solar System. They can range from a few metres across to hundreds of kilometres wide. Asteroids are essentially small, leftover building blocks from the formation of the planets, material that never fused into a larger world. They remain in space, following stable orbits, and they only become hazardous or noteworthy to us when fragments break off or their orbits intersect with Earth. Meteorites, on the other hand, are pieces of asteroids (or occasionally comets or the Moon/Mars) that survive the journey through Earth’s atmosphere and land on the ground. When these fragments are still flying through space, they’re called meteoroids. When they streak through our atmosphere and create a bright trail of light, they’re known as meteors (or ‘shooting stars’). Only if they reach the surface intact do they become meteorites. These fallen pieces are scientifically invaluable because they give us direct physical samples of early Solar System material.

The OSIRIS-REx mission (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) was NASA’s first US mission designed specifically to visit a near-Earth asteroid, collect a sample, and return it to Earth for study. Launched on 8 September 2016, the spacecraft travelled roughly 1.2 billion miles to reach asteroid Bennu (a small, carbon-rich body just under 500 m across) arriving in December 2018 and orbiting it for over a year to map its surface and characterise its composition and geology. After extensive surveys, OSIRIS-REx executed a precise touch-and-go sampling manoeuvre on 20 October 2020 using its TAGSAM arm to collect rocks and dust from a site named Nightingale. The mission then embarked on its long return journey, ultimately delivering the sample to Earth on 24 September 2023, where the capsule parachuted down in Utah and was quickly taken to a clean laboratory for analysis. The scientific significance of OSIRIS-REx goes far beyond the achievement of returning extra-terrestrial material. Bennu’s sample is composed of pristine carbonaceous material that dates back to the early Solar System and contains a mix of organic compounds and minerals that may resemble the ingredients delivered to early Earth by asteroid impacts. Researchers analysing these materials have already identified amino acids, nucleobases, ammonia and other potential building blocks of life, offering powerful evidence that asteroids like Bennu could have contributed to the prebiotic chemistry that helped life arise on Earth. The mission’s findings not only inform our understanding of solar system formation and evolution but also shape ongoing work on other sample-return missions and the broader search for life’s origins in the cosmos.

Japan’s Hayabusa2 mission was a ground-breaking expedition launched by JAXA in 2014 to explore the carbon-rich near-Earth asteroid Ryugu, with the goal of understanding the early Solar System and the origins of organic molecules. After a four-year journey, the spacecraft arrived at Ryugu in 2018 and spent months mapping its rugged, boulder-strewn surface. Hayabusa2 deployed multiple rovers and landers (including the MINERVA-II rovers), which became the first robotic vehicles to hop across the surface of an asteroid, capturing close-up images and collecting environmental data. In a dramatic engineering feat, the spacecraft even used a small explosive device to create an artificial crater, exposing pristine subsurface material never before touched by space weathering. In 2019, Hayabusa2 successfully performed two sample-collection manoeuvres before departing the asteroid and sending its return capsule back to Earth, which landed in Australia in December 2020. Analysis of the Ryugu samples has revealed remarkable scientific discoveries. Researchers found that the asteroid contains primitive, carbon-rich material dating back to the earliest days of the Solar System, including amino acids, nitrogen-bearing compounds, and complex organic molecules that are considered essential ingredients for life. Crucially, the mineralogy of the samples shows evidence that Ryugu’s parent body once contained liquid water, suggesting that aqueous chemical reactions occurred in its interior billions of years ago. These findings support the idea that asteroids like Ryugu could have played a major role in delivering water and the building blocks of life to early Earth, offering powerful clues about how life might emerge elsewhere in the universe.

Mars has long been the centre of the search for life beyond Earth because it shows clear evidence that it was once a far more hospitable world. Billions of years ago, Mars had flowing rivers, long-lived lakes, and possibly even a global ocean, environments where microbial life could plausibly have taken hold. Orbital surveys and rover missions have revealed sedimentary rocks, clay minerals, and ancient shorelines that all point to a wetter, warmer past. These discoveries transformed Mars from a dry, dead planet into a key scientific target. If life ever emerged elsewhere in our Solar System, Mars is one of the places where we are most likely to find its traces. Its relative proximity and well-preserved geological record make it an ideal natural archive for studying early planetary conditions. Today, Mars remains a primary focus because its surface still preserves biosignature clues that Earth has long since erased. Unlike Earth, Mars has no plate tectonics to recycle its crust, meaning any ancient organic molecules, fossil microbes, or chemical fingerprints of life could still be locked within its rocks. Modern missions (from NASA’s Curiosity and Perseverance rovers to ESA’s upcoming ExoMars programme) are actively searching for these signs. They analyse sediments, drill into the surface, and study minerals that could trap organic matter. Perseverance is even collecting samples to be returned to Earth for detailed laboratory examination, a milestone in planetary exploration. If Mars ever hosted life, even at the microbial level, finding evidence of it would fundamentally reshape our understanding of biology and the prevalence of life in the universe.

NASA’s Curiosity rover, which landed on Mars in 2012, has transformed our understanding of the planet’s ancient environment. Designed as a mobile geology laboratory, Curiosity has spent years exploring Gale Crater, a location chosen because its layered sediments record a long history of water activity. The rover discovered rounded pebbles shaped by ancient rivers, mineral-rich mudstones formed in long-lived lakes, and complex organic molecules trapped within Martian rocks. Its instruments (including the SAM chemistry lab and the CheMin mineral analyser) have shown that Mars once had the key ingredients necessary for life: water, energy sources, and essential chemical elements. Curiosity’s findings established Mars as a potentially habitable world in the distant past and laid the scientific foundation for future missions. Perseverance, which landed in 2021, builds on Curiosity’s achievements with a sharper focus, the search for biosignatures, or signs of past microbial life. Operating inside Jezero Crater (an ancient river delta known to preserve fine-grained sediments ideal for trapping organics) Perseverance uses advanced instruments such as SHERLOC and PIXL to scan rocks for chemical fingerprints of life. One of its most roles is collecting and caching rock and soil samples that are intended to be returned to Earth in a future sample-return mission, allowing scientists to study them with tools far more sophisticated than those on the rover. Perseverance also launched the Ingenuity helicopter, proving powered flight on another planet. Together, Curiosity and Perseverance form a powerful tandem: one revealing that Mars was habitable, and the other seeking evidence that life may once have taken advantage of those conditions.

The Panoramic Camera (PanCam) is a vital imaging instrument aboard the ExoMars rover, a collaborative mission between the European Space Agency (ESA) and Roscosmos, designed to explore the surface of Mars with the goal of searching for signs of past life. PanCam provides high-resolution, wide-angle, and multispectral images of the Martian landscape, allowing scientists to study the planet’s geology, surface processes, and atmospheric conditions in unprecedented detail. Its ability to capture 3D panoramic views helps researchers identify interesting rock formations, sediment layers, and mineral deposits, guiding the rover’s movements and sample collection. PanCam’s multispectral filters also allow the detection of minerals and organic compounds by analysing how different wavelengths of light reflect off the surface, providing clues about Mars’ habitability. A surprising fact to find out during this exhibition is that the Natural History Museum has played a significant role in the development, testing, and scientific analysis related to PanCam. NHM scientists have contributed expertise in planetary geology, mineralogy, and spectroscopy, helping to interpret the data that PanCam collects once the rover is on Mars. The museum’s laboratories have been involved in calibrating PanCam’s instruments using Earth-based analogues (rocks and minerals that mimic Martian geology) to ensure accurate readings and reliable comparisons. This collaboration highlights the NHM’s growing presence in cutting-edge planetary exploration, bridging public engagement with front-line research and deepening our understanding of Mars and its potential to host life.

Several of the icy moons in our Solar System are considered some of the most promising places to search for life beyond Earth due to the presence of subsurface oceans beneath their frozen crusts. Notably, Europa, one of Jupiter’s largest moons, has a thick ice shell covering a global ocean of salty liquid water. Tidal forces from Jupiter’s immense gravity create friction and heat inside Europa, which may keep this ocean in a liquid state and drive hydrothermal activity on the moon’s seafloor. Such hydrothermal vents on Earth are known to support rich ecosystems independent of sunlight, suggesting Europa’s ocean could harbour similar life forms. Meanwhile, Enceladus, a smaller moon of Saturn, actively sprays water-rich plumes from fissures near its south pole, ejecting material from a subsurface ocean into space. The detection of organic molecules, hydrogen gas, and other chemicals in these plumes by the Cassini spacecraft indicates that Enceladus has the essential ingredients for life. Beyond Europa and Enceladus, other icy moons like Titan and Ganymede also hold intriguing possibilities. Titan, Saturn’s largest moon, possesses a thick nitrogen-rich atmosphere and lakes of liquid methane and ethane on its surface, along with a potential water ocean beneath its icy crust. While its chemistry is very different from Earth’s, Titan’s complex organic chemistry may offer alternative pathways to life. Ganymede, the largest moon in the Solar System, also harbours a subsurface ocean and possesses its own magnetic field, which could protect potential habitats from harmful radiation. These moons push the boundaries of our understanding of where life can exist, expanding the search beyond traditional “habitable zones” and emphasizing that liquid water and energy sources beneath ice could create hidden oases for life in the cold reaches of our cosmic neighbourhood.

Several space missions have been sent to study Europa, due to its potential to harbour a subsurface ocean and possibly life. The Galileo spacecraft, which orbited Jupiter from 1995 to 2003, was the first mission to provide detailed observations of Europa’s surface and magnetic environment. Galileo’s instruments detected a strong magnetic field induced by a salty, conductive ocean beneath Europa’s ice shell, along with a relatively young, fractured surface marked by ice ridges and possible plumes. These findings revolutionised our understanding of Europa, establishing it as one of the most promising places to search for extra-terrestrial life in the Solar System. Building on Galileo’s legacy, NASA’s upcoming Europa Clipper mission, set to launch in the mid-2020s, will conduct detailed reconnaissance of Europa’s ice shell, subsurface ocean, and surface chemistry. Equipped with advanced instruments (including ice-penetrating radar, spectrometers, and cameras) Europa Clipper will perform dozens of close flybys to map the moon’s surface, identify potential plume activity, and analyse the composition of surface materials for signs of habitability. Complementing this, the European Space Agency’s Jupiter Icy Moons Explorer (JUICE) mission, launching around the same time, will study Europa as well as Ganymede and Callisto, focusing on their potential habitability and interaction with Jupiter’s magnetosphere. Together, these missions aim to unravel the mysteries of Europa’s hidden ocean and assess its capacity to support life.

The JUICE mission is equipped with a suite of advanced scientific instruments designed to explore Jupiter and its three largest icy moons. Among its key instruments is the Jovian Infrared Auroral Mapper (JIRAM), which studies the atmospheres and surfaces of the moons by detecting infrared light, revealing details about their composition and thermal properties. JUICE also carries the Submillimeter Wave Instrument (SWI) to investigate the chemical composition and dynamics of Jupiter’s atmosphere, as well as the icy surfaces of the moons, providing insight into their geophysical and atmospheric processes. To study the moons’ interiors and surfaces, JUICE is equipped with the Radar for Icy Moons Exploration (RIME), a powerful ice-penetrating radar capable of mapping the structure of the ice shells and searching for subsurface oceans. The spacecraft also includes the Ganymede Laser Altimeter (GALA), which will measure the topography of Ganymede’s surface with high precision, helping to understand its geology and tectonics. Other instruments include cameras for high-resolution imaging, spectrometers to analyse surface and atmospheric composition, and magnetometers to study the magnetic environments of the moons. Together, these instruments will provide comprehensive data to assess the habitability of these icy worlds and deepen our understanding of the Jovian system. As someone interested in the potential for life to exist on other worlds, it was rewarding learning about these missions.

Despite the promising conditions on these moons, the likelihood of life thriving there remains speculative because we have not yet directly detected any living organisms or definitive biosignatures. The extreme cold, high radiation levels on the surface, and thick ice layers pose significant challenges for life to originate or persist near the surface, meaning any life would likely be microbial and confined to subsurface oceans. Our current missions focus on gathering detailed data about the moons’ environments, chemistry, and geology to assess habitability more accurately. While we cannot yet say for certain that life exists there, the combination of liquid water, chemical nutrients, and energy sources places these icy worlds at the forefront of astrobiological exploration, and they remain some of the best candidates for finding extra-terrestrial life within our cosmic neighbourhood. The exhibition remains optimistic but the unknowns around the mission are conveyed in an interactive game whereby you have to send your own mission to one of the moons, and achieve a number of pre-designed objectives.

The potential for life to persist at the bottoms of the subsurface oceans on icy moons like Europa and Enceladus largely hinges on the presence of hydrothermal activity and chemical energy sources, similar to those found in Earth’s deep-ocean hydrothermal vents. On Earth, these vents support rich ecosystems that thrive without sunlight, relying instead on chemical reactions between seawater and the rocky ocean floor to provide energy through processes like chemosynthesis. If similar hydrothermal vents exist on these moons, they could create localised environments where microbial life might find the energy and nutrients necessary to survive and even flourish. The interaction between the rocky mantle and the ocean water could release minerals and chemicals such as hydrogen and methane, which are key energy sources for many life forms on Earth, making these deep-sea environments promising habitats. However, for life to persist in these deep oceans, other factors also need to be favourable. The ocean must remain liquid over long periods, sustained by tidal heating or radioactive decay to prevent freezing solid, and there must be sufficient chemical gradients to fuel metabolic processes. Additionally, the ice shell above might provide some protection from harmful cosmic radiation, creating a relatively stable environment compared to the harsh surface.

Hang on? There are ecosystems on Earth that don’t rely on the sun? As mentioned above, hydrothermal vents provide an environment where an array of life thrives in complete darkness and under extreme conditions that would be inhospitable to most organisms. These vents, found deep on the ocean floor, release mineral-rich, superheated water that creates a unique environment where sunlight never reaches. Instead of relying on photosynthesis, the ecosystems here depend on chemosynthesis, a process where bacteria and archaea convert chemicals like hydrogen sulphide and methane into energy. These microorganisms form the foundation of a complex food web, supporting a variety of life forms such as tube worms, giant clams, shrimp, and crabs, many of which have evolved special adaptations to survive intense pressure, high temperatures, and toxic chemicals. These hydrothermal vent communities are some of the most biologically productive and diverse in the deep ocean, illustrating how life can flourish in seemingly extreme and isolated environments. The discovery that life can thrive without sunlight and rely solely on chemical energy suggests that similar processes could sustain microbial life in the subsurface oceans of other worlds, making hydrothermal vents a key focus in the search for extra-terrestrial life.

The search for life beyond our Solar System has been revolutionised by the discovery of thousands of exoplanets (planets orbiting stars other than our Sun) many of which reside in their star’s ‘habitable zone’, where conditions might allow liquid water to exist. Using powerful telescopes like NASA’s Kepler space telescope and Transiting Exoplanet Survey Satellite (TESS), astronomers have identified a diverse array of worlds, from rocky Earth-sized planets to gas giants, expanding our understanding of planetary systems across the galaxy. The focus now is shifting toward characterising these exoplanets’ atmospheres and surfaces to assess their potential habitability. Techniques such as transit spectroscopy allow scientists to detect the chemical fingerprints of gases like oxygen, methane, and water vapor, key indicators that could hint at biological activity or the presence of life. Beyond finding planets in habitable zones, researchers are developing next-generation observatories like the James Webb Space Telescope and future missions designed specifically to image exoplanets directly. These efforts aim to analyse the atmospheres of distant worlds with unprecedented detail, searching for biosignatures, chemical signs that life might be altering a planet’s environment. The search is complicated by the vast distances involved and the challenge of distinguishing life-related signals from non-biological processes, but every new discovery brings us closer to answering one of humanity’s greatest questions: Are we alone in the universe? The study of exoplanets not only guides this quest but also helps us understand how common life-friendly environments might be across the cosmos. Space: Could Life Exist Beyond Earth? makes visitors question this and what it would mean to them personally if life was found outside of our solar system.

There are olfactory elements as well (odd as that sounds) where visitors are invited to ‘smell’ simulated planetary atmospheres or minerals. That choice is playful and memorable, it doesn’t change your mind about the existence of life beyond Earth, but it expands the sensory palette of a museum visit in a way that will lodge in visitors’ memories. The museum wisely accommodates visitors with shorter attention spans: short interpretive panels, clear visual hierarchies, and multiple points for ‘do something now’ engagement. The exhibition achieves several cinematic moments without tipping into spectacle for spectacle’s sake. Large-scale projections of Mars’ surface and immersive panoramas of icy moons create affective beats, sombre, wind-swept Martian plains; black, starlit vistas above Europa’s shell; a dizzying microcosm of early Earth’s chemical stew. These are accompanied by effective sound design (not overwhelming, but atmospheric) that keeps the attention and mood steady.

One strength of the NHM’s approach is that the exhibition weaves museum research into the narrative instead of treating the NHM as a mere venue for loaned objects. Several displays explicitly reference the museum’s scientists and their work on sample analysis and planetary missions. This helps avoid the pitfall of feeling like a ‘best hits’ tour of space artifacts without context. The presence of mission hardware (parachute test rigs, sample-return paraphernalia) alongside meteorites and planetary analogues on Earth (minerals, microbial cultures, extremophile imagery) is cohesive and convincing. There’s also a deliberate attempt to cover a range of possible habitats: not just surface Mars, but subsurface niches, icy moons with global oceans, and exoplanets. The exhibition doesn’t paint Mars as the only plausible candidate, it widens the imaginative aperture to the diverse environments that modern astrobiology considers. This broader framing is both scientifically accurate and narratively richer. There’s a lot of content squeezed into a single circuit, and at peak times the interactive stations can become bottlenecks, try to avoid these if you can. The exhibition sometimes glosses over deeper debates within astrobiology. For example, the philosophical and methodological challenges of defining ‘life’ get lighter treatment than the exhibition’s scientific narratives. A deeper, short-form panel or an audio stop that explicitly examines these epistemic questions would have been welcome for adult visitors who want to probe beyond the introductory level.

The balance between spectacle and substance is well struck. Rather than sensational headlines, the show embraces process, how scientists collect and interpret data, and why certain environments are prioritised in the search for life. For public science literacy, this approach is more valuable than a simplistic ‘life is out there!’ message. Beyond the immediate visitor experience, there’s a larger cultural value here: the NHM is bringing astrobiology (an interdisciplinary field linking geology, biology, chemistry and planetary science) into the mainstream public imagination. That matters because public support and understanding shape funding, missions, and the ethical frameworks that will govern sample return and planetary protection in coming decades. By pairing tactile relics (meteorites and mission paraphernalia) with explanations of current science and hands-on decision-making simulations, Space cultivates scientific literacy about how we search for life and why the search is both technically hard and philosophically profound. The exhibit thus performs a civic function as much as an educational one.

Space: Could Life Exist Beyond Earth? is a well-crafted, timely exhibition that balances accessibility with scientific integrity. It does exactly what a good museum show should: it invites curiosity, makes complex science approachable, and leaves you thinking. The tactile elements (touching Martian fragments and meteorites) are the showstoppers, but the exhibition’s real achievement is that these moments are embedded within a coherent, evidence-based narrative about how scientists evaluate the possibility of life beyond our planet. If you’re planning a visit to the Natural History Museum and have even the faintest fascination with the cosmos, this exhibition is worth the ticket. Book a quieter slot if you can, linger at the tactile displays, try the rover simulation, and take a moment in the immersive film sequences that stitch the exhibition’s concepts together. You’ll leave with your head full of microbe-sized possibilities and a clearer sense of why, in this century, the search for life beyond Earth feels less like philosophical daydreaming and more like practical science.
