Peer inside remnants of an 800-year-old supernova and see a ‘zombie’ star

NASAPeer inside remnants of an 800-year-old supernova and see a 'zombie' star



In the year 1181, an extraordinarily bright supernova lit up the night sky like a firework for an incredible 185 consecutive days. Astronomers have since located its remnants within the constellation Cassiopeia and imaged it — appropriately, it looks like a giant firework.

NASA’s Chandra X-ray Observatory released this new composite image of SNR 1181 that combines data across the electromagnetic spectrum. That data was collected from various Earth- and space-based observatories: ESA’s XMM-Newton, NASA’s Wide-field Infrared Space Explorer, the MDM Observatory in Arizona and Pan-STARRS in Hawaii.
