Shortly after NASA’s Kepler mission began operations back in 2009, it identified what was thought to be a planet about the size of Neptune. Called KOI-5Ab,...
Using the Subaru Telescope and the Keck II telescope at the W. M. Keck Observatory, astronomers have discovered and directly imaged a brown dwarf orbiting...
A team of geobiologists and astronomers from the United States and Germany has identified 24 extrasolar planets that may have conditions more suitable...
Astronomers have discovered an ultra-short-period Neptune-sized exoplanet orbiting the bright Sun-like star LTT 9779.

The newly-discovered planetary core, named TOI-849b, is a gas giant that was either stripped of its gaseous atmosphere or that failed to form one in its...
New estimate suggests that 18% of Sun-like (G-type) stars could have a planet the size of Earth orbiting in their conservative habitable zone.
There may...
Astronomers using data from NASA’s Kepler space telescope have discovered two new planets in the Kepler-160 planetary system. One of the new planets...
Using three instruments on ESO’s Very Large Telescope (VLT), an international team of astronomers has discovered and imaged a giant sub-stellar object...
Magnetic activity on the Sun leads to solar flares, coronal mass ejections, and other space weather that affects Earth. Similar activity on other stars...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have detected 1,216 superflare events on 400 solar-type stars. One of these stars,...
