3D Map of the Milky Way Reveals Billowing Hydrogen Light Clouds

This is part of the first 3D map of our home galaxy, the Milky Way. Over 200 thousand objects are included in the map, which was made up of images from a telescope in the Canary Islands that took hydrogen emission-sensitive pictures of the night sky. The result is that the brighter areas show "hotter" spots where stars are being born. Image via Institute of Astronomy/University of Cambridge. Milky Way Mapped in 3D [Discover News]
