Thanks to a rare combination of luck and technology, astronomers obtained the deepest spectrum ever recorded of a small red dot.<\/p><p>\r\nThis spectrum, equivalent to more than 80 hours of observation due to the gravitational lensing effect of a background galaxy cluster, revealed more than 40 spectral lines.<\/p><p>\r\nThey all point to a rapidly growing black hole, surrounded by a thick cloud of ionized gas that reprocesses the light emitted near it.\r\n<\/p><p>\r\n&#8220;When we first saw the spectrum, it was like having all the pieces of a jigsaw puzzle scattered on the floor,&#8221; explained Kokorev.<\/p><p>\r\n&#8220;We put each piece together and realized that they fit perfectly into the &#8216;star-black hole&#8217; model.&#8221;\r\n<\/p><p>\r\nAmong the evidence are lines of hydrogen, oxygen, helium, and especially an &#8220;iron forest&#8221; with 16 lines of this element.<\/p><p>\r\nThe width and intensity of these lines indicate the presence of a very dense medium around a high-energy source-exactly what is expected of a black hole in the process of accretion (swallowing matter).<\/p><p>\r\nThe model also explains why these objects are weak in X-rays: the emission is absorbed by the cocoon of gas.<\/p><p>\r\nThe James Webb data were complemented by observations from the Hubble Telescope, which helped to understand why the &#8220;Balmer bounce&#8221; (a typical feature of these points) appears weaker: the object is surrounded by a giant host galaxy.<\/p><p>\r\nThis resolves another question: some of the extra blue light comes from the stars of this galaxy, and the black hole doesn&#8217;t need to be as massive as previously thought.\r\n<\/p><p>\r\nWith this, the Universe doesn&#8217;t need to be &#8220;rewritten.&#8221; Everything fits into the evolutionary history we already know.<\/p><p>\r\n&#8220;Nothing is broken, and that makes the puzzle of our Universe even more beautiful,&#8221; said Kokorev.\r\n<\/p><p>\r\nScientists believe we are close to a unified picture for these small red dots.<\/p><p>\r\nIn the coming years, deeper observations should definitively confirm what fuels these mysterious objects from the early cosmos.<\/p><p>\r\nThe James Webb Telescope, once again, proves to be the most powerful tool for exploring the first chapters of the Universe&#8217;s history.\r\n<\/p><p>\r\n<blockquote class=\"twitter-tweet\" data-media-max-width=\"560\"><p lang=\"en\" dir=\"ltr\">The James Webb space telescope finds the strongest evidence yet of &#8216;black hole stars&#8217;<a href=\"https:\/\/x.com\/hashtag\/blackholestars'src=hash&#038;ref_src=twsrc%5Etfw\">#blackholestars<\/a><br><br>NASA, ESA, and CSA&#8217;s James Webb Space Telescope continues to unravel mysteries of the early Universe<br>Read more:<a href=\"https:\/\/t.co\/UuZuiaF7vf\">https:\/\/t.co\/UuZuiaF7vf<\/a> <a href=\"https:\/\/t.co\/E57FKJhuu0\">pic.twitter.com\/E57FKJhuu0<\/a><\/p>?
