In late 2019, the previously unremarkable galaxy SDSS1335+0728 started shining brighter, which was believed to be caused by a massive black hole.<\/p>\n
To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory\u2019s Very Large Telescope<\/a>, to track how the galaxy\u2019s brightness has varied.<\/p>\n \u201cImagine you\u2019ve been observing a distant galaxy for years, and it always seemed calm and inactive,\u201d said Paula S\u00e1nchez S\u00e1ez, an astronomer at ESO.<\/p>\n \u201cSuddenly, its core starts showing dramatic changes in brightness, unlike any typical events we’ve seen before.\u201d<\/p>\n SDSS1335+0728 is now classified as having an \u2018active galactic nucleus\u2019 (AGN) \u2013 a bright, compact region powered by a massive black hole \u2013 after it brightened dramatically.<\/p>\nThe brightness is unlike anything we\u2019ve witnessed before<\/h3>\n
