Life may not get blasted off any of the known "super-Earth" worlds as readily as it can from our planet, scientists find. The discovery suggests that any intelligent aliens that develop on such ...

If aliens are watching Earth, they might be able to detect us from the radio signals we beam to Mars to control our rovers there. Astronomers have now listened in on the nearby TRAPPIST-1 system to ...

Do aliens sleep? You may take sleep for granted, but research suggests many planets that could evolve life don’t have a day and night cycle. It’s hard to imagine, but there are organisms living in ...

New research finds that certain large exoplanets are shrinking due to internal processes, creating an abundance of rocky 'super-Earths'. When you purchase through links on our site, we may earn an ...

Comets may have delivered the seeds of life to Earth, scientists say. They could also have delivered similar building blocks of life to other planets. A new study could help narrow down the search for ...
