Gaia produces stellar density map of the Milky Way

This image, based on housekeeping data from ESA's Gaia satellite, is no ordinary depiction of the heavens. While the image portrays the outline of our Galaxy, the Milky Way, and of its neighbouring Magellanic Clouds, it was ...

An image gallery gift from Swift satellite
