One of the strangest objects ever spotted by the James Webb Space Telescope may point to a new stage in the evolution of supermassive black holes.<\/p>\n

Astronomers have gathered strong evidence for the existence of a so called \u201cblack hole star,\u201d a black hole surrounded by gas so dense and hot that, from far away, it looks like a giant star.<\/p>\n

The case rests on two particularly important James Webb observations. The first is MoM-BH*-1, an extremely red object that already existed just about 660 million years after the Big Bang.<\/p>\n

The second, GLIMPSE-17775, offers the most detailed spectrum of a \u201clittle red dot\u201d obtained so far and strongly reinforces the same interpretation.<\/p>\n

What Is a \u201cBlack Hole Star\u201d?<\/p>\n

The term sounds contradictory, but it describes a specific theoretical model.<\/p>\n

At the center of the object sits a black hole growing rapidly as it absorbs matter. Around it lies an extremely dense shell of gas. The radiation produced near the black hole does not escape directly into space. Instead, it is absorbed and re-emitted by the gas, so the whole system looks from a distance like a giant star.<\/p>\n

It is not, then, a star in the classic sense. Its energy does not come from nuclear fusion, as in the Sun, but from matter falling toward the black hole.<\/p>\n

The Reddest Object Yet Seen by James Webb<\/p>\n

MoM-BH*-1 was spotted as an extremely bright red spot in James Webb\u2019s data and lies in the constellation Cetus. Its light has traveled to us from a time when the universe was still very young, about 660 million years after the Big Bang.<\/p>\n

The object has a strikingly red appearance, and its emission shows a sharp change below a specific wavelength. These traits were among the reasons it caught researchers\u2019 attention.<\/p>\n

The team that studied the object, led by Rohan Naidu of the MIT Kavli Institute for Astrophysics and Space Research, argues that its spectrum does not fit easily into any of the known categories of early universe objects.<\/p>\n

An Object That Looks Like a Star But Behaves Like a Black Hole<\/p>\n

The observations show an object with features resembling a stellar atmosphere, but with energy behavior pointing to a black hole.<\/p>\n

That is the central puzzle scientists are trying to solve.<\/p>\n

Computer simulations show that a black hole surrounded by extremely dense layers of gas can produce a spectrum resembling that of a very large star. The gas essentially acts as a \u201cshell\u201d that transforms the light coming from the central black hole.<\/p>\n

The idea isn\u2019t limited to a single object. If the interpretation holds up, it could explain a significant share of the mysterious population of \u201clittle red dots\u201d that James Webb has revealed.<\/p>\n

The Second Object Provides The Strongest Evidence Yet<\/p>\n

Especially significant is GLIMPSE-17775, studied by a team led by Vasily Kokorev of the University of Texas at Austin.<\/p>\n

The object sits behind the galaxy cluster Abell S1063, and its image is amplified by gravitational lensing. The cluster\u2019s gravity acts like a natural magnifying lens, letting James Webb pick up details that would otherwise be very hard to detect.<\/p>\n

Webb captured a 30 hour spectrum which, thanks to gravitational lensing, is equivalent to roughly 80 hours of observation. Scientists identified more than 40 spectral lines, more than any other little red dot found so far.<\/p>\n

A \u201cForest\u201d of Iron Lines Reveals What\u2019s Happening Inside<\/p>\n

Among the most important findings are 16 iron lines, which the researchers describe as an \u201ciron forest.\u201d<\/p>\n

The hydrogen, oxygen, and helium lines also don\u2019t fit a simple model of a rotating gas cloud. The best explanation involves a dense shell in which light is scattered by electrons.<\/p>\n

The picture that emerges is one of a powerful energy source at the center, most likely a black hole accumulating matter at a very fast rate, wrapped in a dense gas shell.<\/p>\n

Why \u201cLittle Red Dots\u201d Puzzled Astronomers<\/p>\n

Little red dots have been one of the biggest surprises from James Webb since its scientific observations began in 2022.<\/p>\n

They are small, extremely red objects found at very large cosmological distances. Their true nature remains a subject of intense scientific debate.<\/p>\n

At first, their brightness posed a problem: if all their light came from stars, some of the earliest galaxies would have had to build up enormous mass in an extremely short time.<\/p>\n

The presence of a black hole at the center changes the picture. A significant part of the energy doesn\u2019t come from the fusion of billions of stars, but from matter falling toward the central black hole.<\/p>\n

Could They Be the \u201cSeeds\u201d of Supermassive Black Holes?<\/p>\n

This may be where the discovery matters most.<\/p>\n

The supermassive black holes found today at the centers of galaxies are one of cosmology\u2019s big puzzles: how did they manage to reach such enormous masses so early in the universe\u2019s history?<\/p>\n

The \u201cblack hole star\u201d scenario offers a possible answer.<\/p>\n

These objects could represent an early, gas shrouded growth phase, during which black holes rapidly gain mass before evolving into much larger objects.<\/p>\n

Rohan Naidu has argued that such objects may be the original \u201cseeds\u201d from which the supermassive black holes of today\u2019s galaxies grew.<\/p>\n

The Mystery Isn\u2019t Solved Yet<\/p>\n

Despite the striking evidence, astronomers don\u2019t consider the matter closed.<\/p>\n

The model of a black hole wrapped in dense gas explains many features of little red dots, but other theoretical approaches exist too. Among them is the possibility that some of these objects are related to supermassive stars in the final stages before their collapse.<\/p>\n

At the same time, newer studies have identified hundreds of candidate objects showing features consistent with the \u201cblack hole star\u201d model, suggesting the phenomenon may not be limited to a handful of extremely rare sources.<\/p>\n

The next crucial step is observing more such objects with James Webb and other telescopes. If the same spectral features keep showing up, \u201clittle red dots\u201d could turn out to be far more than a strange feature of early universe images.<\/p>\n

They may be the fingerprint of the process that gave rise to the giant black holes now sitting at the hearts of galaxies.<\/p>\n","protected":false},"excerpt":{"rendered":"\u039cake us preferred on Google One of the strangest objects ever spotted by the James Webb Space Telescope…\n","protected":false},"author":2,"featured_media":645985,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[64,63,131,128,285],"class_list":["post-855797","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-au","tag-australia","tag-nasa","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/855797","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/comments?post=855797"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/posts\/855797\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media\/645985"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/media?parent=855797"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/categories?post=855797"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/au\/wp-json\/wp\/v2\/tags?post=855797"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
