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 ...

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

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

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 ...

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 ...

He’s here to tell us why the European Space Agency’s Gaia spacecraft is so important—and why, even though the Gaia mission is technically coming to a close, its scientific legacy is only ...

Earth may have cooled during a close encounter with dense star clouds. Interstellar dust from the Orion region might have shaped our ancient climate.

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 ...
