Search for Life

Self-sustaining chemical reactions that could support biology radically different from life as we know it might exist on many different planets, a new study finds.

A European collaboration aims to break through some of the technological barriers to the exploration of icy moons like Jupiter's Europa, using Antarctica as a proving ground.

NASA has named a new director of UFO research who will oversee the agency's studies into UAP, or unidentified anomalous phenomena.

Lawmakers in Mexico heard testimony this week about the presence of alien life on Earth that included two "corpses of extraterrestrials." NASA's UAP study team isn't so sure.

"But we don't know what these UAP are," NASA chief says. The agency is appointing a new UAP research director.

NASA's independent UAP study team will present its initial findings during a briefing on Thursday (Sept. 14). Here's how to watch it live.

The Pentagon's official office for addressing UFOs has a new website where U.S. government and military personnel can report their own sightings.

How humanity responds to the first contact with intelligent alien life could determine the very fate of our species. Here's what we can learn from history.

Cool stars with powerful magnetic fields could have remarkably fast stellar winds that strip away their planets' atmospheres, making even "habitable zone" worlds less friendly to life.

China is paying close attention to what NASA will and will not be able to afford in the coming years, as the space agency's budget gets chopped up by U.S. lawmakers.

During a congressional hearing on Wednesday (July 26), military witnesses and members of Congress demanded more transparency from the U.S. government when it comes to UFOs.

The chorus of voices calling for the U.S. government to spill the beans on possible alien visitation of Earth is louder than ever. But are we ready for such a revelation?

The U.S. House of Representatives will hear from several witnesses who will offer accounts of unidentified anomalous phenomena (UAP) in order to assess government transparency surrounding the issue.

Rocky exoplanets could possess large amounts of water from the moment they form, observations by the James Webb Space Telescope suggest.

Some rivers on ancient Mars flowed for long enough stretches to create bona fide habitable environments on the Red Planet, a new study suggests.

NASA's Perseverance rover has found an intriguing menagerie of organic molecules in a Martian crater, but their source remains unclear.

Finding liquid water on exoplanets is 100 times more probable than previously thought, boosting the odds of alien life significantly, a new study suggests.
