Miracle find! James Webb Telescope discovers farthest known supermassive black hole

[ad_1] Supermassive black holes are incredibly powerful objects in space that even have the power to hold galaxies together with their strong gravity. They have the ability to destroy anything that comes too close to them. And luckily enough, the James Webb Telescope has discovered the farthest supermassive black hole known so far.The distances in space are unbelievably huge. According to the University of Texas at Austin, the new supermassive black hole is located at the center of a galaxy called CEERS 1019. Amazingly, this galaxy was formed just 570 million years after the Big Bang. Along with the supermassive black hole, scientists also found two smaller black holes that formed 1 billion and 1.1 billion years after the Big Bang. CEERS 1019 SignificanceCEERS 1019 is not only very old ...

Mysterious Gamma-ray burst baffles scientists, causes NASA rethink on how black holes are formed

[ad_1] A recent NASA study could change the understanding of gamma-ray bursts and black hole formation. Know all about it here. Almost a year ago on December 11, Earth was witness to a high energy gamma-ray burst (GRB) which was suspected to be emitted from the outskirts of a galaxy around 1 billion light-years away. What made this cosmic burst unusual was the fact that it did not submit to any one pre-defined category of gamma-ray bursts. It left scientists baffled and put a doubt into their previous understanding of GRBs.According to NASA, GRBs are classified into two categories – long bursts and short bursts. Long bursts which emit gamma rays for two seconds or more and originate from the formation of dense objects like black holes in the centers of massive collapsing stars. Short ...

NASA and ISA’s new space observatory helps solve mystery of supermassive black holes

[ad_1] Imaging X-ray Polarimetry Explorer (IXPE) launched last December as a collaboration between the U.S. space agency NASA and the Italian Space Agency. Most galaxies are built around humongous black holes. While many of these are comparatively docile, like the one at our Milky Way's center, some are fierce - guzzling surrounding material and unleashing huge and blazingly bright jets of high-energy particles far into space.Using data from the recently deployed Imaging X-ray Polarimetry Explorer (IXPE) orbiting observatory, researchers on Wednesday offered an explanation for how these jets become so luminous: subatomic particles called electrons becoming energized by shock waves moving at supersonic speed away from the black hole. The researchers studied an exotic object called a bl...

Polarized X-rays reveal shape, orientation of very hot matter near black hole

[ad_1] Researchers' recent observations of a black hole called Cygnus X-1 reveal new details about the configuration of hot matter in the region . The first observations of a mass-accreting black hole from the Imaging X-Ray Polarimetry Explorer (IXPE) mission reveal new details about the configuration of extremely hot matter in the region immediately surrounding it. Researchers are using measurements of the polarization of X-rays to test and refine models that describe how black holes swallow matter, becoming some of the most luminous sources of light including X-rays in the universe. Matter is heated to millions of degrees as it is pulled toward a black hole. This hot matter glows in X-rays. Researchers are using measurements of the polarization of these X-rays to test and refine ...

Massive Black Hole discovered in our cosmic backyard! Know how black holes are formed

[ad_1] A team of astronomers has discovered a massive black hole in the cosmic backyard. Know how black holes are formed and other details here. Black holes are one of the most interesting topics for scientific researchers. As per the latest update, a massive black hole has been discovered in our cosmic backyard. The black hole is estimated to be twelve times the mass of the sun. According to a report by universetoday.com, "after consulting the Gaia Data Release 3 (DR3), a team of astronomers led by the University of Alabama Huntsville (UAH) recently observed a black hole in our cosmic backyard. As they describe in their study, this monster black hole is roughly twelve times the mass of our Sun and located about 1,550 light-years from Earth. "But do you know what actually black holes ...
