By combining multiwavelength observations with archival data spanning several decades, the researchers concluded that the fading was caused by a rapid decrease in the gas flowing into the supermassive black hole at the galaxy&#8217;s center. The discovery shows that the activity of supermassive black holes can change dramatically on timescales short enough to be observed within a human lifetime.<\/div>\n<p><a target=\"_blank\" href=\"https:\/\/phys.org\/news\/2026-03-distant-galaxy-decades-supermassive-black.html\" target=\"_blank\">Go to Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An international team led by a researcher at the Chiba Institute of Technology has discovered an extremely rare phenomenon: a galaxy about 10 billion light-years away whose brightness dropped to one-twentieth of its original level in just 20 years.
