The intrepid mapping mission has collected more than three trillion observations that'll change the way we see our neck of ...

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 ...

The most detailed infrared map of the Milky Way contains incredible images of over 1.5 billion objects within our galaxy. The 200,000 images were collected by the Visible and Infrared Survey ...

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 ...

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 ...
