Our Moon is hostile to life. But this doesn’t mean that moons elsewhere in the universe are inhospitable to life. Far away from the solar system, moons of free-floating planets can keep water in ...

For generations, artists and science-fiction writers have imagined alien landscapes beneath twin sunsets. The image became iconic in popular culture long before astronomers confirmed that planets ...

Barnard’s Star hosts four hostile small planets whose unusual chemistry and orbital rhythm reveal how compact planetary ...

Scientists say moons around rogue planets wandering through the galaxy could remain warm enough for life thanks to tidal heating and hydrogen-rich atmospheres. These dark, starless worlds may have had ...

If you were hoping we’d find alien life hanging out on a cozy, pint-sized planet anytime soon, then you should know that ...

For a world to maintain an atmosphere long enough for life to gain a foothold, it seems it needs to be at least as big as ...

Astronomers have identified a clue hidden in the light of certain stars that's already led them to discover seven new alien planets, with more expected to come. To be clear, these alien planets likely ...

The race to compile a sort of catalogue of the planets orbiting distant Suns is intensifying, with the upcoming Nancy Grace Roman Space Telescope, for instance, set to spot tens of thousands of such ...

There is no chance in hell our species will be able to reach another Earth-like planet in the Universe in the foreseeable future, so the only way we can get a sense of the habitability of such places ...

A new study proposes detecting life in space by spotting patterns across many planets instead of focusing on one at a time. If life spreads and changes planetary environments, it could leave behind ...

WHITE dwarfs may be dying, but their light could be just right to sustain life as we know it. That could make habitable planets even more common than we think. Many planet-hunting missions have ...

Astronomers have revised the mass of nearby exoplanet GJ 3378 b, recasting it as a rocky super‑Earth in the habitable zone and renewing interest in its potential to host alien life.
