For the first time, scientists have found evidence for a secondary atmosphere on an exoplanet, created by volcanism beneath the surface. The planet, GJ 1132 b, is thought to have once been a sub-Neptune, but now is a rocky world the size of Earth.

Through 12 years of photographing and stitching together individual astrophotography images, Finnish astrophotographer J-P Mestavainio has created a 1.7 gigapixel panorama of our Milky Way galaxy.

A study here on Earth simulating the weightless conditions of space travel showed that the longer the participants were exposed to a low-gravity environment, the more they perceived facial expressions as angry.

Astronomers have discovered a restless supermassive black hole that's moving within its galaxy.

New research suggests that worlds with subsurface oceans are common in our galaxy, and might be even better environments for life than Earth's oceans.

China and Russia are cooperating in plans to build a lunar research outpost on the moon. The China National Space Administration and Roscosmos - Russia's space agency - made the announcement in a memorandum dated March 9, 2021.

SETI's Nathalie Cabrol believes a widespread biosphere exists on Mars that has migrated underground over the past few billion years.

NASA's Perseverance rover on Mars has just sent back its first initial science results, as well as some new audio recordings of wind and the rover's laser zapping rocks.

New research solves a decades-long riddle: from where do the highest-energy cosmic rays originate? Even supernovae - exploding stars - can't explain them. Now it seems these sorts of cosmic rays may come from clusters of young, hot, massive stars.

Scientists have confirmed the presence of water and organic materials that are essential for life on the surface of asteroid Itokawa. The samples of rock and dust were returned to Earth by the Japanese Hayabusa spacecraft in 2010.
