The results are intriguing, but analysing the atmospheres of exoplanets is no easy task.

Whistleblower allegations that the government possesses UFOs may not be backed up by public physical evidence, but some argue that listening for extraterrestrial life is the first phase of contact.

While UFO videos might seem compelling, they’re rarely backed up with evidence. A sociologist explains why claims of alien life gain traction through both social and mass media every few years.

Five out of the six essential elements required for life on Earth were known to exist on Enceladus. Now the sixth and final one has been found too.

The Milky Way likely has hundreds of millions of planets that are promising targets to probe for signs of life outside our solar system.

Regions on exoplanets called "terminator zones" could be prime sites for liquid water and possibly harbor life, a new study shows.

"...Hansel and Gretel dropped breadcrumbs to make sure they'd find their way back. In our scenario, the 'breadcrumbs' are miniaturized sensors..."

A future mission to Enceladus, one of Saturn's 83 moons, could discover its potential for harboring alien life—all without ever landing.
