NEW DISCOVERY Strottner-Drechsler-Sainty Object 1 A GIGANTIC PLASMA ARC IN THE DIRECTION OF THE ANDROMEDA GALAXY Our international team of amateur astronomers and scientists made a surprising discovery in August 2022. In a cross-national collaboration, the researchers and amateur astronomers studied the newly discovered giant nebula. The arc has an extent of about 1.5 by 0.45 degrees, is only 1.2 degrees from the center of M31, and is located southeast of the main body of the Andromeda galaxy. It may be the largest structure of its kind in the near vicinity in the universe. M31 is undoubtedly one of the most photographed deep sky objects ever. This makes the discovery of such a large structure in close proximity to the galaxy all the more surprising. The exact origin of the [O III] emission is still unclear, but circumstantial evidence points to likely scenarios. *** More information on Astrobin: https://www.astrobin.com/1d8ivk/ The paper: Discovery of Extensive [O iii] Emission Near M31 – IOPscience
