Gaia unexpectedly discovered a giant exoplanet and a puzzling brown dwarf, challenging planetary formation theories and ...

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

The Gaia space telescope has created the largest 3D map of the Milky Way, measuring distances and luminosities for up to 2 billion stars. After 11 years in space, Gaia ceased operations on January ...

Our Solar System is in motion and cruises at about 200 kilometres per second relative to the center of the Milky Way. During ...

Fast-moving stars in the Milky Way indicate there could be a supermassive black hole in the neighboring Large Magellanic ...

Astronomers have discovered that the Solar System traversed the Orion star-forming complex, a component of the Radcliffe Wave galactic structure, approximately 14 million years ago. This journey ...

If a star orbits a black hole, it will appear from a distance to be orbiting empty space. Gaia projects the star’s orbit on a plane in the sky while ground-based telescopes meanwhile track how light ...

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 ...

For the new study, researchers sought to find out what these two are and what they're up to more than a decade later – using data from the Keck Observatory in Hawaii and the European Space Agency's ...

NASA scientists have detected a star and trailing exoplanet that may be sailing through the Milky Way with unprecedented ...

Gaia, a mission that has driven substantial progress in our understanding of the Milky Way, came through again. "We find that half of the unbound HVSs discovered by the HVS Survey trace back not ...
