Data from the Gaia spacecraft shows that even unassuming stars can host monumental companions like massive planets.

By tracing the corkscrew wobble of two stars as they move through the sky, the Gaia space mission has discovered one new ...

Astronomers have long relied on two main methods to detect exoplanets—the transit method, which looks for dips in a star’s ...

Gaia-4b is considered a super-Jupiter planet, a relatively cold gas giant, orbiting its star over 570 Earth-days. That star ...

The ESA’s Gaia mission mapped the positions and velocities of stars with extreme precision by measuring about one billion ...

Using data from the European Space Agency's Gaia mission, scientists have found a huge exoplanet and a brown dwarf. This is the first time a planet has been uniquely discovered by Gaia's ability to ...

NASA's Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an 'arrow' -- a far smaller blue dwarf galaxy -- shot ...

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 ...
