The stars as seen from Earth would have looked dimmer 14 million years ago, as the solar system was in the middle of passing ...

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

Using Europe's Gaia space telescope, astronomers have identified 55 runaway stars being ejected at high speeds from a densely ...

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 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 ...

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 ...

Previously, these had been difficult to identify, but with the Gaia space observatory's data having mapped the Milky Way with high precision in three dimensions, more of these streams have been ...

Wobbling stars reveal hidden companions in Gaia data Date: February 4, 2025 Source: European Space Agency Summary: Using data from the European Space Agency's Gaia mission, scientists have found a ...

Credit: 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 ...
