"Rediscovering the 800-Year-Old Supernova: A Stunning New Image"

NASA's Chandra X-ray Observatory has captured a composite image of SNR 1181, the remnant of a supernova explosion that occurred 800 years ago, believed to be caused by the merger of two stars. The image shows a spherical nebula surrounded by stars, with a hot white dwarf star at its center. This rare explosion, likely a sub-luminous Type Iax event, has left behind a unique opportunity for studying such phenomena, and the composition of the remnant suggests it was formed in a thermonuclear explosion.

"Unveiling the Legacy: New Portrait of an 800-Year-Old Supernova"

NASA's Chandra X-ray Observatory has captured a composite image of supernova remnant SNR 1181, which exploded in the year 1181 and was recently discovered by modern telescopes. The remnant suggests a special kind of supernova called a sub-luminous Type Iax event, resulting from the merger of two white dwarf stars, leaving behind a "zombie" star. The remnant, one of the hottest stars in the Milky Way, presents a unique opportunity for studying rare explosions, despite the Chandra Observatory facing budget cuts.

"Unveiling the Mysteries of an 800-Year-Old Explosion's Echo"

Scientists have discovered the remnant of a rare supernova explosion that appeared in the night sky in 1181, providing a new spectacular view of the event that was visible for 185 days. The composite image, created using data from various telescopes, shows a nearly circular nebula with a central star in the constellation Cassiopeia. X-ray observations reveal the full extent of the nebula, while studies of its composition suggest it was formed in a sub-luminous Type Iax event, a special kind of supernova resulting from the merger of two white dwarf stars. This discovery offers a unique opportunity for studying rare explosions and the formation of "zombie" stars.
