Scientists have discovered complex molecules in the gas and vapor plumes escaping from Enceladus's icy core — and one of them, hydrogen cyanide, is a precursor for life.
A new NASA survey identified 17 exoplanets that may have the right conditions for liquid water oceans hidden beneath icy shells. The planets could be good candidates in the search for alien life.
On Dec. 26, 2022, NASA's MAVEN Orbiter witnessed Mars' magnetic shield and atmosphere drastically "balloon" outward by thousands of miles. The sudden expansion was triggered by a rare gap in solar wind.
Possible amino acids spewing from Enceladus' subsurface ocean can survive impact with a spacecraft, lab experiments show.
We worked out how many trips each of the solar system's eight planets has taken around the sun over the past 4.6 billion years.
Salty glaciers discovered in craters near Mercury's north pole may have the right conditions for extreme forms of life, new research suggests.
The massive planet LHS 3154b orbits a star much smaller than Earth's sun, and its discovery could upend everything we think we know about how solar systems form.
After months of meticulous planning, NASA's Odyssey Orbiter finally captured a unique view of the Red Planet's horizon, which is similar to what future Martian astronauts might see.
Six exoplanets with sizes between Earth and Neptune have been in rhythm with each other since they were born around the same star 4 billion years ago, new research suggests.
