CR7 -  The brightest Galaxy in the early Universe

These massive, brilliant, and previously purely theoretical objects were the creators of the first heavy elements in history - the elements necessary to forge the stars around us today, the planets that orbit them, and life as we know it. 

Astronomy Photo of the Day: 7/01/15 — NGC 2367

Using the power of the Wide Field Imager (WFI) Camera mounted to the ESO’s 2.2 Meter Telescope, astronomers have taken a stunning new image of a cluster of stars—all of which, sit approximately 7,000 light-years from Earth toward the constellation of Canis Major.

Called NGC 2367, the stars within this open cluster are believed to be around 5 million years old—So young, they burn brightly and intensely, with their blue-tinged hue adding yet another color to an already impressive palette. It doesn’t hurt that the stars have set surrounding hydrogen gas alight, which gives the region its red glow.
