Gaia, a mission designed to map stars, has accidentally become a planet hunter. Using precise astrometry, it detected stellar ...

In a rare double-whammy space assault, the European Space Agency's Gaia spacecraft was recently slammed by a micrometeoroid and struck by a solar storm, leaving it unable to function properly.

Gaia-4b is also the first planet detected by the European Space Agency's Gaia spacecraft using the astrometric technique. NEID is a high-precision radial-velocity spectrograph that is designed to ...

The planet is the fourth world to be spotted in data from the European Space Agency's Gaia mission, which was designed to map a billion stars in our Milky Way galaxy, cataloguing their masses ...

ESA illustration The exoplanet is Gaia's first independent success using the "wobble" technique, aka astrometry, according to the space agency. Since the mission launched in 2013, the spacecraft ...

uses data collected by ESA's Gaia spacecraft to confirm the existence of two mysterious celestial objects. Gaia-4b is a 'Super-Jupiter' exoplanet, and Gaia-5b a brown dwarf. These massive objects ...

Gaia-4b is considered a super-Jupiter planet, a relatively cold gas giant, orbiting its star over 570 Earth-days. That star is estimated to be 64 percent the mass of the sun. That makes Gaia-4b one of ...
