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.
Reference NASA's Perseverance rover isn't just exploring the Red Planet. The life-hunting robot will also help a little bit of Mars make it to Earth a decade or so from now, if all goes according to plan.
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?
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.
More evidence of the potentially life-indicating molecule phosphine has been discovered in Venus' atmosphere, opening the next chapter in a heated debate.
Astronauts on NASA's Artemis moon missions might look for signs of life in shadowed polar craters — life that could have traveled with people from Earth.
A new search for extraterrestrial life has scientists looking inward — toward the center of our galaxy.
The Rocket Lab's pioneering private mission to Venus, which had been set to launch last month, has been delayed until at least 2025.
Four-time astronaut Scott Kelly spoke with Space.com about UFOs and why air and space are so 'prone to optical illusions' that lead to reports of unidentified anomalous phenomena.
During the opening remarks in today's meeting of NASA's UAP study team, members stressed that the biggest roadblock standing between us and understanding unidentified phenomena is a lack of data.
A European Mars orbiter beamed a coded message to Earth today (May 24), kicking off a weeks-long project designed to help us prep for a real signal from E.T.
A new project called 'A Sign in Space' will give scientists and laypeople around the world practice at decoding a message from intelligent aliens.
A newfound exoplanet that lies 90 light-years from Earth may be studded with active volcanoes, whose emissions could sustain an atmosphere.
NASA's TESS spacecraft spotted two super-Earth planets as they crossed the face of their star within its 'habitable zone.'
Reference Scientists have found nearly 5,000 exoplanets since the first such world was confirmed orbiting a sunlike star in 1995. These ones are most similar to Earth.
Intelligent aliens looking for life in the universe might be able to find Earth using our radio signals, a new SETI study suggests.
New research suggests that Hycean exoplanets would suffer from a catastrophic runaway greenhouse effect, causing their oceans to boil away.
