The energy arises from gas violently falling into a supermassive black hole that is surrounded by a cloud of tiny particles of rock and soot along with\u00a0mostly hydrogen gas.<\/p>\n<p>Black holes are extraordinarily dense\u00a0objects\u00a0possessing gravitational pulls so powerful even light cannot escape. Supermassive black holes, which reside at the center of many galaxies, including our own, are the largest of them.<\/p>\n<p>Messier 77, also called NGC 1068 or the Squid Galaxy, is located 47 million light years \u2013 the distance light <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">travel<\/a>s in a year, 5.9 trillion miles (9.5 trillion km) \u2013 from Earth in the constellation Cetus. Its supermassive black hole has a mass roughly 10 million times greater than our sun.<\/p>\n<p>The\u00a0observations, using the European Southern Observatory\u2019s Very Large Telescope in Chile\u2019s Atacama Desert, provided strong support for what is called the \u201cunified model\u201d of active galactic nuclei. This model holds that all active galactic nuclei are basically the same but that some <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>ear from the vantage point of Earth to have different properties.<\/p>\n<p>Some look intensely bright because the position of their ring-like cloud does not obscure the gas plummeting into the black hole from our viewing angle. Others look dark because the cloud blocks our view of what is truly happening.<\/p>\n<p>Messier 77\u2019s active galactic nucleus is one of the dark ones, but the\u00a0new\u00a0observations\u00a0indicate that it actually possesses the same qualities as the bright ones.<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"514\" src=\"https:\/\/nypost.com\/wp-content\/uploads\/sites\/2\/2022\/02\/Space-embed.jpg?quality=90&amp;strip=all&amp;w=1024\" alt=\"A handout image obtained by Reuters on February 16, 2022, shows the active galaxy Messier 77, captured with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument on European Southern Observatory's (ESO's) Very Large Telescope (left), and a blow-up view of its active galactic nucleus, as seen with the MATISSE instrument on ESO's Very Large Telescope Interferometer (right).\" class=\"wp-image-21243669\" srcset=\"https:\/\/nypost.com\/wp-content\/uploads\/sites\/2\/2022\/02\/Space-embed.jpg?quality=90&amp;strip=all 1024w, https:\/\/nypost.com\/wp-content\/uploads\/sites\/2\/2022\/02\/Space-embed.jpg?quality=90&amp;strip=all&amp;w=512 512w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\"\/><figcaption>A handout image obtained by Reuters on February 16, 2022, shows the active galaxy Messier 77, captured with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument on European Southern Observatory\u2019s (ESO\u2019s) Very Large Telescope (left), and a blow-up view of its active galactic nucleus, as seen with the MATISSE instrument on ESO\u2019s Very Large Telescope Interferometer (right).<\/figcaption><figcaption><span class=\"credit\">Reuters <\/span><\/figcaption><\/figure>\n<p>\u201cThe dust and gas in these clouds are probably blown out of the atmospheres of stars at a larger distance \u2013 hundreds of light years \u2013 from the black hole, and are falling in towards the center under the influence of the black hole gravity,\u201d said Violeta <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/game\/\" data-internallinksmanager029f6b8e52c=\"7\" title=\"Game\" target=\"_blank\" rel=\"noopener\">Game<\/a>z Rosas, an astronomy doctoral student at Leiden University in the Netherlands and lead author of the research published in the journal\u00a0<a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.nature.com\/articles\/s41586-021-04311-7\">Nature<\/a>.<\/p>\n<p>\u201cSome clouds spiral in towards the black hole while others are pushed up into a \u2018fountain\u2019 that falls back onto the galaxy.
