"Our team of amateur astronomers made a surprising discovery – a huge plasma arc next to the Andromeda Galaxy (M31). The arc has an extension of about 1.5 x 0.45 degrees, is only 1.2 degrees away from the centre of M31 and is located southeast of the main body of the galaxy. Scientists are now investigating the newly discovered giant in a transnational collaboration. It could be the largest such structure nearest to us in the Universe. The Andromeda Galaxy is the closest spiral galaxy to the Milky Way. It is undoubtedly one of the most photographed deep-sky objects." Marcel Drechsler, Xavier Strottner, Yann Sainty
