Today, ESA's Gaia mission releases a goldmine of knowledge about our galaxy and beyond. Among other findings, the star surveyor surpasses its planned potential to reveal half a million new and faint stars in a massive cluster, identify over 380 possible cosmic lenses, and pinpoint the positions of more than 150 000 asteroids...

Southwest Research Institute scientists are using telescopes to observe the asteroid Psyche in the infrared, providing context for NASA's upcoming Psyche mission. Dr. Stephanie Jarmak is using the James Webb Space Telescope (JWST) to look for water signatures on the metallic surface of Psyche, while Dr. Anicia Arredondo is using...

A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b...
