Scientists hunt for the 2nd-closest supermassive black hole near Earth

[ad_1] Two astrophysicists at the Center for Astrophysics Harvard & Smithsonian have suggested a way to observe what could be the second-closest supermassive black hole to Earth. Two astrophysicists at the Center for Astrophysics Harvard & Smithsonian have suggested a way to observe what could be the second-closest supermassive black hole to Earth: a behemoth 3 million times the mass of the Sun, hosted by the dwarf galaxy Leo I.The supermassive black hole, labeled Leo I*, was first proposed by an independent team of astronomers in late 2021. The team noticed stars picking up speed as they approached the center of the galaxy -- evidence for a black hole but directly imaging emission from the black hole was not possible. Now, CfA astrophysicists Fabio Pacucci and Avi Loeb sugges...

Closest black hole to Earth found and it is terrifying! Know how big and near it is

[ad_1] Gaia BH1 is a recently discovered black hole and researchers believe that it is the closest black hole to the Earth. Black holes have always perplexed humans. They are the opposite of whatever we see. In simple terms, a black hole is a region in space where the gravity is so strong that not even light can escape from it. And still we only have surface level understanding of black holes. And the main reason behind that is that it is extremely difficult to spot a black hole as you cannot see it normally. As a black hole devours light, it blends in with the darkness of space. The only time we can actually see it is when it interacts with the space around it. But this might be changing soon because a group of researchers has discovered the closest black hole to the Earth.The resear...

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 ...
