Amazing

The Dark Energy Survey

1 month ago

Behold the ghostly tendrils of the Vela Supernova Remnant, the cosmic corpse 💀 of a gigantic star that exploded as a supernova around 11,000 years ago! This spectacular 1.3 gigapixel image is one of the biggest ever made of this object with the powerful, 570-megapixel U.S. Department of Energy-fabricated Dark Energy Camera 🤯.

Located around 800 light-years away in the constellation Vela (the Sails), this nebula is one of the nearest supernova remnants to Earth. Though the unnamed star ended its life thousands of years ago, the shockwave its death produced is still propagating into the interstellar medium, carrying glowing tendrils of gas with it.

The striking reds, yellows, and blues in this image were achieved through the use of three DECam filters that each collect a specific color of light. Separate images were taken in each filter and then stacked on top of each other to produce this high-resolution color image that showcases the intricate web-like filaments snaking throughout the expanding cloud of gas.

DECam is mounted on the National Science Foundation (NSF)'s Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO).
