The Medulla nebula, Abell 85 - AstroBin The Medulla nebula, also called Abell85, LBN 576 and CTB-1, is a supernova remnant CTB-1 is the expanding gas shell that was left when a massive star toward the constellation of Cassiopeia exploded about 10,000 years ago This deep sky object it's pretty faint and needs some deep integrations to show some detail
Medulla Nebula (CTB 1, Abell 85) - Deep⋆Sky Corner In Abells second publication of his survey of old planetary nebulae in 1966 he listed the nebula with the number 85 and a diameter of 2077 x 2077 arcseconds He described it as a not symmetrical ring with bright spots or regions
Holmberg 15A - Wikipedia Holmberg 15A (abbreviated to Holm 15A) is a supergiant elliptical galaxy and the brightest galaxy of the Abell 85 galaxy cluster in the constellation Cetus, about 241 4 megaparsecs (787 3 million light-years) from Earth [2]
Abell 85 - Sky Telescope CTB 1 Abell 85 or LBN 576 is a very faint Supernova Remnant in the constellation of Cassiopeia It is located approximately 9780 light years away, spans approx 98 light years in diameter and is thought to be around 10,000 years old
CTB1 (Abell 85) - A Supernova Remnant in Cassiopeia Upon early discovery, CTB1 was thought to be a planetary nebula, so Abell included it in his catalog of planetary nebulae as Abell 85 Further research showed that CTB1 is, in fact, a supernova remnant
Abell 85 (CTB-1) - AstroKin Abell 85 (also catalogued as CTB 1 or LBN576), is a large supernova remnant in the constellation Cassiopeia, which was originally catalogued by George Abell as a planetary nebula
CTB1 Abell 85 - The Garlic Nebula - AstroBin Abell 85 is a fascinating supernova remnant in the Cassiopeia constellation It is a very dim object with an angular size that is about the same as the full moon That is to say that if you could see it with your eyes, it would be as large as a full moon in the sky
