Using the All-Sky Automated Survey for Supernovae (ASAS-SN) system, on February 22, 2023, the team detected a sudden surge in brightness followed by a rapid dimming in the galaxy NGC 3799, located about 160 million light-years from Earth.<\/p>\n<section class=\"article-banner first-banner ads-336x280\">\n         <!-- \/4988204\/Phys_Story_InText_Box --><\/p>\n<\/section>\n<p>&#8220;While black holes destroying stars have been seen before, this is the first one we have seen this close using visible light,&#8221; said Willem Hoogendam, an IfA graduate student who co-led the research. &#8220;This could give us a much better understanding of how SMBHs grow and collect material around them.&#8221;<\/p>\n<p>Follow-up observations were taken with IfA&#8217;s Asteroid Terrestrial Last Alert System (ATLAS) telescopes on Maunaloa and Haleakal\u0101, W.M. Keck Observatory on Maunakea, and other ground- and space-based observatories. Hoogendam, working with fellow IfA grad student Jason Hinkle and faculty advisor Ben Shappee, analyzed these data to determine that the burst of brightness was caused by a Tidal Disruption Event (TDE).<\/p>\n<p>TDEs happen when a star gets too close to a SMBH and is torn apart by its strong gravitational force, with the black hole devouring the star&#8217;s mass. Research findings will be published in the <i>Monthly Notices of the Royal Astronomical Society<\/i>.<\/p>\n<p>&#8220;This discovery suggests that black holes ripping stars apart nearby could be more common than previously thought\u2014we just haven&#8217;t witnessed it happening frequently,&#8221; said Hoogendam.<\/p>\n<figure class=\"mb-4\" itemscope=\"\" itemtype=\"http:\/\/schema.org\/VideoObject\">\n    <meta itemprop=\"name\" content=\"Star ripped apart by black hole in rare discovery\"\/><br \/>\n    <meta itemprop=\"url\" content=\"https:\/\/scx2.b-cdn.net\/gfx\/video\/2024\/star-ripped-apart-by-b.mp4\"\/><br \/>\n    <meta itemprop=\"description\" content=\"Generic animation of blackhole breaking a star apart.
