Although it gave no real indication of how life in fact first evolved, the experiment left astrobiology with a framework for investigating the chemistry of alien worlds. In 1975, the first Mars ...

With rivers, lakes and even seas made of liquid methane and ethane, plus a hidden underground ocean of water, Saturn's moon Titan has long fascinated scientists as a place where alien life might ...

A new study backs up that idea — but with a twist. Yes, alien life could be there, researchers say, but probably not in the abundance we once hoped. "We focus on what makes Titan unique when ...

This hole might lead to underground caves. Scientists think these caves could hold alien life. The US Geological Survey has mapped many potential cave entrances. NASA plans to explore these pits ...

Scientists have found further evidence of possible biosignature gases on the nearby exoplanet K2-18b, strengthening the case that it could support alien life ... Based on its size and other ...

The first sign of possible extraterrestrials detected in the cosmos didn't come in the form of little green aliens flying around in saucer-shaped spacecraft. In fact, the life that could be ...

NASA has revealed a 328-foot-wide hole on Mars, potentially a gateway to subterranean caves that could harbor alien life. These pits, formed by meteor impacts, might offer protection from harsh ...

Scientists using The James Webb Space Telescope have uncovered potentially earth-shattering evidence indicating a faraway world could be home to alien life. A team at the University of Cambridge ...

The discovery hinges on the fact that on Earth, both DMS and DMDS are produced almost exclusively by microbial life, particularly ... is uncovering more alien worlds, and it is powerful enough ...

NASA's James Webb Space Telescope detected a possible sign of alien life on a distant planet. Alien life has still not been confirmed through science or through studying UFOs (or UAPs).
