Cosmic bombardment may have opened Earth's crust for prebiotic chemistry
Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of ...

Could it be aliens? From Cheyava Falls on Mars to exoplanet K2‑18b—here's what scientists really think
It may seem like we are on the verge of discovering alien life. In 2025, a press release stated that we have the "strongest hints yet" of extraterrestrial life on the exoplanet K2-18b. And when talking about a collected sample ...

ExoMars rover targets vast bed of clay in search for life
In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a vast ocean once covered the landing ...

How Jupiter may have redirected life's ingredients toward Earth 4.5 billion years ago
NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable. They also suggest a new role for Jupiter in the distribution ...

Astrobiology's looming statistical crisis
Multi-billion-dollar space telescope programs aren't only feats of aerospace engineering. They also feature "lies, damn lies, and statistics." Or at least statistics. They definitely feature those, as does all good observational ...

Icy moons' ability to host life could be revealed through an ecology-based method
New observatories and spacecraft missions are probing environments in our solar system that could potentially host life but have long remained hidden. Icy moons like Saturn's Enceladus and Jupiter's Europa likely contain ...

How a giant moon and a steam atmosphere built the recipe for life
4.5 billion years ago was an interesting time for Earth. The atmosphere was thick and what we would now think of as toxic. The moon, which was freshly formed, looks much more massive than it does today and faintly glows with ...

New study has shone a new light on searching for habitable worlds
When astronomers discovered the first planet outside our solar system, it was orbiting a pulsar, one of the most extreme, radiation-blasted environments imaginable. Not exactly the kind of place you'd expect to find a planet, ...

A natural chemistry laboratory in protostar shock waves
Life exists because elements combine to form complex organic molecules. Astrochemistry studies this process, trying to understand how nature creates carbon-based molecules critical for life. One source for these types of ...

Mars's manganese 'bathtub ring' reveals ancient ocean timeline and its potential for life
Past research has indicated Mars's largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers ...
Bare supercontinent may have tipped ancient Earth into 'Snowball' phase
About a billion years ago, Earth started to come into its own. It was past the awkwardness of its younger years full of growing pains and turmoil: comet strikes and slimy water, including the Great Oxidation Event that flipped ...
Could aliens ever visit Earth? An aerospace scientist unpacks the challenges of interstellar spaceflight

How Mars can help us understand 'marginal' exoplanets
Mars holds a special place in the solar system. It represents marginal habitability. This means it transitioned from warm and wet and potentially hospitable, to cold and dry and inhospitable.

Supermassive black holes can render exoplanets uninhabitable at great distances
The thinking around exoplanet habitability is mostly concerned with a planet's distance from its star. Too close, and any surface water is boiled away into space. Too far, and surface water is frozen. Both are severe limits ...
