Astronomers rely on clear observations to study celestial objects, but cosmic dust alters what we see, making stars appear ...

When we observe distant celestial objects, there is a possible catch: Is that star I am observing really as reddish as it ...

CNN’s Kaitlan Collins caught up with DJ Daniel, the 13-year-old cancer survivor honored by President Donald Trump during his ...

Astronomers have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy. For their map, the astronomers used 130 million spectra from ESA's Gaia mission, results ...

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

"The Gaia mission has been the most successful ESA mission ever if you look at the number of publications. There are around five publications per day based on data from Gaia," says Andreas Korn ...

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 ...

Voluminous clouds of cosmic dust permeate our galaxy, but only recently has software allowed detailed observations of the ...

Astronomers from the Max Planck Institute for Astronomy have constructed the first detailed 3D map of the properties of cosmic dust in our home galaxy. For their map, the astronomers used 130 million ...

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 ...

Astronomers are buzzing over a groundbreaking discovery made by the European Space Agency’s (ESA’s) Gaia spacecraft, which found two giant cosmic objects hiding in plain sight. For the first ...
