https://phys.org/space-news/astrobiology/ en-us Astrobiology news stories about origin and evolution of life in the Universe Aliens have long been a staple of science fiction. Yet the possibility of intelligent life beyond Earth is more than a matter of imagination—it is also a subject of serious scientific inquiry. Professor Woong-bae Zee of Sejong University's School of Liberal Studies has recently published an astronomy paper that places the word "alien" front and center. https://phys.org/news/2026-11-nearby-rocky-worlds-alien-astronomers.html Astrobiology Mon, 09 Nov 2026 12:40:07 EST news713443981 A new experiment reveals that Earth's microbes can grow in harsh conditions similar to what may exist just below the surface of Mars, suggesting new directions in the search for potential cellular life on the red planet. https://phys.org/news/2026-11-microbial-growth-simulated-mars-conditions.html Astrobiology Thu, 05 Nov 2026 09:00:10 EST news713005621 New evidence from gas seeping above volcanic rifts suggests Mars is not geologically dead deep inside, but merely sleeping. Fresh fissures along the Alba Mons region hint at active spots under the surface, where gases from inside the planet may be making their way up to the surface. https://phys.org/news/2026-11-european-orbiter-fresh-hints-volcanic.html Astrobiology Wed, 04 Nov 2026 19:40:07 EST news713035561 Finding a signal from an extraterrestrial civilization takes more than just pointing a telescope in the right direction. We may also need to listen at exactly the right time. https://phys.org/news/2026-11-alien-scientists-game-theory.html Astrobiology Tue, 03 Nov 2026 17:50:01 EST news712949224 It's a dizzyingly busy time for scientists searching for life on distant planets. To date, astronomers have cataloged more than 6,000 planets beyond our solar system and are searching the atmospheres of the most promising worlds for chemicals that might be byproducts of life. Astrobiologists are particularly interested in atmospheres like Earth's that trap enough heat to support liquid water on the planet's surface, which scientists consider the key factor in determining whether a planet can support life as we know it. https://phys.org/news/2026-11-scientists-earth-simulation-life-planets.html Astrobiology Mon, 02 Nov 2026 13:50:01 EST news712846766 Asteroid Ryugu and some carbonaceous meteorites, which are thought to have similar origins in the early solar system, are known as chemically "primitive" materials because they preserve the chemical composition of the early solar system remarkably well. Yet these rocks also reacted extensively with water after they formed, transforming many of their original minerals into new ones. https://phys.org/news/2026-11-overlooked-material-ryugu-meteorites-ancient.html Astrobiology Mon, 02 Nov 2026 11:40:13 EST news712839301 When we think of extraterrestrial intelligence that might be out there among the stars, we tend to think of creatures not too unlike us, though maybe with gray skin, probably bald and with big black eyes. We focus on the familiar, humanoids. But there are many intelligent species on Earth that are nonhumanoid: dolphins, crows, pigs and—with swarm if not individual intelligence—ants and bees. The film "Arrival" conceived of hexapod beings more capable than humans and with a more sophisticated communication system. https://phys.org/news/2026-10-extraterrestrial-firefly-communications-distinguish-alien.html Astronomy Fri, 30 Oct 2026 08:50:02 EDT news712568508 Scientists at the University of New Mexico have played a key role in identifying a rare, 4.1-billion-year-old Martian meteorite that provides new evidence that the red planet may have once had a wetter, Earth-like environment. https://phys.org/news/2026-10-rare-billion-year-martian-meteorite.html Astrobiology Thu, 29 Oct 2026 19:30:05 EDT news712513021 The theory that comets delivered the molecular building blocks for life on Earth is a long-standing one, since comets are known to carry many of these molecules. However, a new study challenges this idea. https://phys.org/news/2026-10-comets-didnt-seed-life-earth.html Astrobiology Wed, 28 Oct 2026 06:00:10 EDT news712240261 Earth may have produced much of its water during the planet's formation, as rocky pebbles reacted with the hydrogen-rich atmosphere surrounding the young planet, according to new research published in Nature Geoscience. The findings offer a potential explanation for how Earth acquired one of the essential ingredients for life and suggest that similar water-producing processes could be common on rocky planets beyond our solar system. https://phys.org/news/2026-10-earth-planet-grew.html Astrobiology Tue, 27 Oct 2026 11:40:01 EDT news712312933 The ocean beneath Saturn's moon Enceladus lies under kilometers of ice, but some of its contents do reach the surface. Jets near the south pole spray out water vapor and icy particles, offering a way to investigate the hidden ocean without drilling down to it. https://phys.org/news/2026-10-salt-crystals-clues-life-beneath.html Astrobiology Sat, 17 Oct 2026 11:40:01 EDT news711288914 Plants begin responding to spaceflight almost immediately after leaving Earth, according to a new University of Florida study that captured the earliest stages of biological adaptation during a commercial suborbital mission. Published in the journal npj Microgravity, the study reports the results of an experiment conducted by a UF astronaut during Blue Origin's New Shepard NS-26 flight on Aug. 29, 2024. https://phys.org/news/2026-10-shift-gene-minutes-spaceflight-reveals.html Space Exploration Fri, 16 Oct 2026 19:00:01 EDT news711376001 A Ph.D. student at the University of Sydney has produced the first comprehensive classification system and map of Martian soils, creating a new framework that could help scientists compare landscapes across the Red Planet and identify promising locations for future exploration, habitation and food production. https://phys.org/news/2026-10-comprehensive-mars-soil-classification-framework.html Astrobiology Fri, 16 Oct 2026 16:40:06 EDT news711372541 An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory is a partner (NSF NRAO), has combined expertise from across the globe to open a new window on how the organic molecules that seed planets, and potentially life, form in space. https://phys.org/news/2026-10-alcohol-space-exotic-methanol-planet.html Astronomy Wed, 07 Oct 2026 10:40:18 EDT news710587401 In early 2024, laboratory-grown neurospheres (i.e. clusters of neural stem cells) were sent to the International Space Station (ISS) to be exposed to microgravity. The return trip was delayed several times due to bad weather in the landing zone. As a result, the cells were outside controlled culture conditions for longer than anticipated—beyond the limit of what they were expected to survive. https://phys.org/news/2026-10-stem-cells-survive-unexpectedly-rough.html Space Exploration Tue, 06 Oct 2026 12:40:10 EDT news710500141 Earth seems like a troubled place right now, but at least our cosmic surroundings appear peaceful. This is not universally true, as explosions, collisions and other dangers lurk in other places and times. https://phys.org/news/2026-10-life-cosmos-universe-supercomputer-yields.html Astronomy Tue, 06 Oct 2026 10:40:29 EDT news710498341 The truth is out there—but identifying signs of life in space involves an intense search for biosignatures within our solar system and beyond. However, developing sensitive yet compact technologies capable of detection has proven to be an out-of-this-world challenge. https://phys.org/news/2026-10-electrical-technique-life-space.html Astrobiology Mon, 05 Oct 2026 05:00:06 EDT news710162162 Saturn's icy moon Enceladus hides a global ocean beneath its frozen surface. From fractures near its south pole, material from this ocean is ejected into space as a plume of water vapor and ice particles. These particles offer scientists a rare opportunity to investigate an extraterrestrial ocean without drilling through kilometers of ice. https://phys.org/news/2026-09-enceladus-ocean-spray-chemically-diverse.html Astrobiology Sun, 04 Oct 2026 12:00:01 EDT news709890049 As humanity looks toward future bases on the moon, plant cultivation will be critical for sustaining life there.

However, around 3.8–3.6 billion years ago, it may have looked very different. Geological and mineral evidence suggests that, in its distant past, the planet experienced periods warm and wet enough for water to exist on its surface, potentially forming rivers, lakes and even an ocean in the northern hemisphere. https://phys.org/news/2026-10-ancient-life-chemistry-clues-mars.html Astrobiology Thu, 01 Oct 2026 10:40:11 EDT news710065741 Is there life elsewhere, or is Earth unique in the universe? This is one of humanity's great unanswered questions. One way to approach this mystery is to investigate how life began here on Earth. Our research explores the conditions in which a mixture of molecules somehow transformed from chemistry into biology. https://phys.org/news/2026-09-sugar-meteorites-survival-early-earth.html Astrobiology Wed, 30 Sep 2026 12:20:06 EDT news709980361 Four and a half billion years ago, Earth and Mars were born in the rotating cloud of gas and dust that would eventually become our solar system. Yet exactly how the planets formed remains one of the most disputed questions in planetary science. https://phys.org/news/2026-09-earth-mars-built-cosmic-recipes.html Astrobiology Wed, 30 Sep 2026 12:00:01 EDT news709980001 Although Mars may have once resembled Earth, the rocky red planet now appears far from hospitable. Still, certain details—such as ice-bound water—pique researchers' curiosity. As on Earth, ice on Mars contains valuable records of past climate that could reveal whether the planet hosts, or has ever hosted, life. https://phys.org/news/2026-09-north-pole-mars-dusty-scientists.html Astrobiology Wed, 30 Sep 2026 09:00:22 EDT news709975621 New research led by the University of Michigan is helping set the stage for future observatories to characterize rocky planets outside our solar system, planets that could prove life isn't confined to Earth. The new research represents the most sensitive modern search for giant planets in a nearby binary system—a system with two stars orbiting each other—known as 70 Ophiuchi AB, or 70 Oph AB. https://phys.org/news/2026-09-suns-giant-planets-nearby-binary.html Astrobiology Tue, 29 Sep 2026 14:20:06 EDT news709903801 Scientists have helped solve a longstanding mystery about how Earth remained habitable after oxygen first accumulated in its atmosphere more than 2 billion years ago, providing evidence that ancient ocean chemistry sustained life-friendly conditions. https://phys.org/news/2026-09-ocean-chemistry-life.html Astrobiology Tue, 29 Sep 2026 13:40:11 EDT news709903621 What are the chances of finding extraterrestrial life in our solar system? Frank Postberg, a professor of planetary science at Freie Universität Berlin, has published a study in Science Advances with an international team of researchers. They present new evidence that it is easier to determine the constituents of the ocean hidden beneath Enceladus's icy surface than previously assumed. https://phys.org/news/2026-09-great-news-saturn-moon-enceladus.html Astrobiology Fri, 25 Sep 2026 14:00:21 EDT news709396040 In the search for extraterrestrial life, it makes sense to first look for rocky planets with an atmosphere, like Earth. Without an atmosphere, a planet can't have surface water. But of the more than 6,300 exoplanets cataloged thus far, the vast majority are not rocky, and only a handful of the rocky worlds appear to have an atmosphere. https://phys.org/news/2026-09-coolest-lava-world-atmosphere-clues.html Astrobiology Thu, 24 Sep 2026 18:20:06 EDT news709469461 When the universe was still in its infancy—only 500 million years after the Big Bang, or about 3% of its current age—some of the universe's earliest stars and galaxies had already formed. Astronomers have long predicted that much of the gas surrounding these young galaxies must have remained relatively pristine, composed mostly of hydrogen and helium, the primordial ingredients available in the newborn cosmos. https://phys.org/news/2026-09-jwst-early-galaxies-seeding-universe.html Astrobiology Thu, 24 Sep 2026 05:00:04 EDT news709373161 Conditions on early Earth may have become stable enough to sustain the chemistry associated with the origins of life around 4.33 billion years ago, according to new research co-led by Planetary Science Institute senior scientist Oleg Abramov. https://phys.org/news/2026-09-earth-gained-optimal-conditions-life.html Astrobiology Wed, 23 Sep 2026 10:40:16 EDT news709373041 Science fiction suggests that life on other planets, if it exists, is likely far more advanced than life on Earth. A recent study suggests otherwise. https://phys.org/news/2026-09-nearby-advanced-alien-civilization-pounce.html Astrobiology Tue, 22 Sep 2026 16:00:04 EDT news709307941
