This colorful web of wispy gas filaments is the Vela Supernova Remnant , an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago. This image was taken 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’s NOIRLab.
The Vela supernova remnant is visible in long exposure photographs in the constellation Vela. It is the result of a star more massive than the Sun reaching the end of its life. As the progenitor star evolved the fusion deep in its core ceased. The lack of fusion means the cessation of the outward pushing thermonuclear force, the star instantly implodes under the immense force of gravity. The inward rushing material rebounds leading to the supernova explosions we see.

Dark Energy Camera Captures Largest Image of Vela Supernova RemnantThe Dark Energy Camera (DECam) has captured the largest image ever released by the camera, featuring the Vela supernova remnant. The image, at 1.3 gigapixel in size, showcases the capabilities of DECam, which was originally designed to study distant galaxies and dark energy. The Vela supernova remnant, located 800 light-years away, is a cloud of gas and dust formed from the explosion of a massive star thousands of years ago.

Webb finds evidence for neutron star at heart of young supernova remnantNASA's James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, was a core-collapse supernova, meaning the compacted remains at its core formed either a neutron star or a black hole.
