Supernova Remnant Puppis A

Puppis A (Pup A) is a supernova remnant about 100 light-years in diameter and roughly 6500–7000 light-years away. This object is one of the many cosmic treasures found within the new 1.3 gigapixel Vela Supernova Remnant image, captured with the Department of Energy-fabricated Dark Energy Camera, mounted on the US National Science Foundation's Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab. Although Pup A overlaps the Vela Supernova Remnant, it is four times more distant.
