We can judge the value of any scientific endeavour based on how much of our knowledge it overturns or transforms.

The result is an unprecedented large-scale 3D map of the galaxy. And that map shows that the edges of the Milky way bend slightly, giving it a warped S shape. "Our map shows the Milky Way disk is ...

The ESA will conduct technology tests for several weeks after Gaia’s observations end, before the spacecraft leaves its orbit ...

In their study published Thursday in the journal Science, they showed that by measuring the distance between classical Cepheid variable stars within the galaxy, they could develop a three-dimensional ...

Researchers from the University of Connecticut have created the first 3D maps of star-forming gas clouds in one of the most ...

This collage highlights a small selection of regions of the Milky Way imaged as part of the most ... [+] detailed infrared map ever of our galaxy. Here we see, from left to right and top to bottom ...

We can judge the value of any scientific endeavour based on how much of our knowledge it overturns or transforms. By that metric, the ESA’s Gaia mission is a resounding success. The spacecraft gave us ...

Issues delivered straight to your door "I expect Gaia's best results are still to come." ...

By reconstructing stellar orbits using real Milky Way stars with accurately determined parameters, the team quantified the Galaxy’s mass-weighted chemical abundances and age structure.

This illustration shows a stage in the predicted merger between our Milky Way galaxy ... ASTRO 3D and the University of Oklahoma. “We’re now seeing where the galaxy’s influence stops ...
