Explanation: The faint and somehow menacing cometary globule CG4 reaches through the center of this deep southern skyscape. About 1,300 light-years from Earth toward the constellation Puppis, its head is about 1.5 light-years in diameter and its tail about 8 light-years long. That's far larger than the Solar System's comets that it seems to resemble. In fact, the dusty cloud contains enough material to form several Sun-like stars and likely has ongoing star formation within. How its distinctive form came about is still debated, but its long tail trails away from the Vela Supernova remnant near the center of the Gum Nebula, while its head could represent the rupture of an originally more spherical cloud. Still, the edge-on spiral galaxy also near picture center is not actually being threatened by CG4. The galaxy lies in the distant background more than 100 million light-years away.

I see red gunpowder in a blast of stars....what would a psychiatrist make of that? It's beautiful though!

Dawn entered orbit around Ceres about a half hour ago so we should be getting some pictures from there by this afternoon.

Thank you for the post and ping, Mr. Civilizations.

Thanks cripplecreek! That’ll be heavily covered in APoD I hope.
