NASA’s boldest plan yet to find alien life in our solar system targets the most unlikely place: Venus. With its scorching surface and crushing atmosphere, Venus seems uninhabitable - until you ...

Does alien life exist on an exoplanet? On TikTok, a University of Oxford astrophysicist cast doubt that extraterrestrial life may exist on K2-18b.

A recent study, led by astrophysicist Nikku Madhusudhan at the University of Cambridge, suggests the answer might be no. Based on observations from NASA’s James Webb Space Telescope, the study points ...

And because there is no profit-driven incentive for discovering life on a distant world, corporate entities cannot and will not fill NASA’s void.

A U.K.-led mission aims to determine if microbial life exists in Venus’s clouds by detecting phosphine and ammonia.

Is there really alien life on this exoplanet? We asked 10 experts. A team of astronomers claims to have sniffed out a “biosignature” in the atmosphere of a distant planet called K2-18b.

Is there alien life on K2-18b? A strong possibility exists that extraterrestrial life can be found on a distant exoplanet known as K2-18b. Using observations from NASA’s James Webb Space ...

In collaboration with a Japanese university, NASA researchers used supercomputers to predict when life will no longer be possible on Earth.

Each time biosignatures are found, biologists confront the ambiguous distinction between life and non-life, and the difficulty of extrapolating characteristics of life on Earth to alien environments.

Astronomers have made a detection suggesting biosignatures, or signs of biological activity, on an exoplanet located 124 light-years away. But experts are skeptical.
