Members of the Sternberg Astronomical Institute of the Lomonosov Moscow State University have been studying changes in the appearance of emissions from around the supermassive black hole in the center of a galaxy called NGC 2617. The center of this galaxy underwent dramatic changes in appearance several years ago, becoming much brighter; astronomers were able to make groundbreaking observations. The results of these investigations have been published in the Monthly Notices of the Royal Astronomical Society.
