Bizarre Jupiter-Mass Exomoon Challenges Everything We Know About Planetary Systems
Astronomers have found what may be the first convincing evidence of a giant "exomoon" beyond our solar system, but the unusual object is already...
The Sun has a ‘switch-off’ moment—and it could help predict space weather years ahead
Scientists have discovered a new way to predict how active the sun's next solar cycle will be years before it reaches its peak.
The research...
Mysterious Little Red Dots may be the birthplaces of the universe’s oldest star clusters

Astronomers find tiny rocky planets locked in eternal day and night
Astronomers have taken their most detailed look yet at the planetary system orbiting Barnard's Star, one of the Sun's closest stellar neighbors, and the...
Moon’s far side keeps a hidden record of how Earth slows the solar wind
For billions of years, the moon has been constantly bombarded by the solar wind—a stream of charged particles flowing outward from the sun.
Scientists have...
