After cataloging thousands of worlds beyond our solar system, astronomers are now closing in on a far rarer prize: a moon ...

A nearby binary star system is bereft of giant planets, but scientists think it may still be a decent place to look for life.

Researchers have developed a new coronagraph that could make it possible to see distant exoplanets obscured by light from their parent stars. Researchers have developed a new coronagraph -- an optical ...

What can star variability—changes in a star's brightness over time—teach astronomers about exoplanet habitability? This is ...

Exoplanets are planets outside Earth's solar system. In 1995, a gas giant named 51 Pegasi b, which orbits a star similar to Earth's sun, etched its name in history as the first exoplanet ever ...

After decades of searching, astronomers might finally be on the verge of discovering thefirst confirmed exomoon, a natural ...

Scientists have detected the first direct evidence of a coronal mass ejection from a star beyond our Sun, specifically the M dwarf StKM1-1262. This ma ...

The first exoplanet discovery in 1995 around a Sun-like star challenged the then-prevailing model of planetary system formation based solely on our solar system, revealing the existence of massive ...
