SNR G116.9_00.1, LBN 576, Abell 85 "The Last Breath of Mr. PZh" Final sum

LBN 576 \ (or SNR G116.9+00.1, Abell 85 and CTB 1) — a faint supernova remnant located almost 10,000 light-years from Earth. It is also estimated to be about 10,000 years old. Until recently it was considered a planetary nebula, but recent studies confirm that it is a supernova remnant, the closest known to Earth. This object, also called the Burnt Air Balloon or the Medulla Nebula, is the remains of ejecta formed during a supernova explosion. The expanding shock wave of material interacts with a large gas cloud, causing various elements such as hydrogen, oxygen, and sulfur to emit light at specific wavelengths. The image also includes a large emission nebula consisting of several massive clouds of gas and dust.
