The Gaia mission, launched by the European Space Agency, has completed a decade of groundbreaking astronomical observations, collecting over three trillion data points on two billion stars and ...

ESA’s decade-long Milky Way Gaia mapping mission still has tons of data to release over the next few years. Expect surprises.

Gaia, the European Space Agency’s observatory that is mapping the Milky Way, has completed the sky-scanning phase of its mission - and its fuel is now nearly empty.

The Andromeda galaxy is our closest galactic neighbour, barring dwarf galaxies that are gravitationally bound to the Milky ...

The European Space Agency's (ESA) Milky Way mapper Gaia has completed the sky-scanning phase of its mission, racking up more than three trillion observations over the past decade. Gaia was launched on ...

The European Space Agency's Milky Way-mapping space mission Gaia, which involves UCL researchers, has completed its sky-scanning phase, racking up more than three trillion observations of two billion ...

The Gaia space telescope, launched by the European Space Agency (ESA) in December 2013 with the aim of creating a detailed three-dimensional map of the Milky Way galaxy, has observed about 2 ...

The work has revealed that Andromeda is a lot more chaotic than expected. Similar to what recently retired Gaia did for the ...

Map of the Milky Way plane obtained from data from the Gaia catalog (eDR3). The upper part shows a region where the Palomar 5 star cluster and its tidal tails are observed (DESI Legacy Imaging ...

By that metric, the ESA’s Gaia mission is a resounding success. The spacecraft gave us a precise, 3D map of our Milky Way galaxy and has forced us to abandon old ideas and replace them with compelling ...

From detecting ‘ghosts’ of other galaxies and multiple streams of ancient stars that merged with the Milky Way in its early history, to finding evidence for an ongoing collision with the Sagittarius ...

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 ...
