Scientist caught Black Hole Swallowing a Star
What is Black Hole?
Black hole is a geometrically defined region of space-time exhibiting such strong gravitational effects that nothing including particles and electromagnetic radiation such as light-can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform space-time to form a black hole.
In other word a black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into tiny space. This happen only when a star die. No light can get out, so human can’t able to see the black hole. But the black holes are visible only with space telescope and with some special tools. Size of a black hole can be very big or very small. Scientist reveled that the smallest black holes are as small as just one atom. But the mass of this very tiny black hole is very huge.
How Do Black Holes Form?
Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or collapses. When this happens, it causes a supernova. A supernova is an exploding star that blasts part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
What Scientist caught?
In first time of history an international team of astrophysicist led by a Hopkins University scientist, witnessed a black hole swallowing a star and ejecting a flare of matter moving at nearly the speed of light. They observed a new way for plasma to escape the gravitational pull of a supermassive black hole.
The results are based on radio observations tracking a star as it gets from apart by the supermassive black hole. This radio observation located in the center of PCG 43234 a galaxy approximately 290 million light year away from the earth. For the first time, astronomers were able to show that this burst is followed by a radio signal from the matter that was able to escape the black hole by traveling away in a jetted outflow at nearly the speed of light.
Asatronomers captured a black hole eating a star and then sicking a bit of it. The scientists tracked a star about as big as our sun as it pulled from its normal path and into that of a supermassive black hole before being eaten up. Then they saw a high-speed flare get thrust out, escaping from the rim of the black hole.
“It’s the first time we see everything from the stellar destruction followed by the launch of a conical outflow, also called a jet, and we watched it unfold over several months,” Sjoert van Velzen at Johns Hopkins University.
Astronomers think that the supermassive black hole can be found at the center of the every massive galaxies. In future we will found a black hole in our own Milky Way galaxy. Their powerful galaxies can pull in object that come to close – however they do not suck in objects from far away. They often steadily pull in dust and gas from surrounding space.
The meeting was an intense, yet very productive exchange of ideas about this source. We still get along very well; I actually went for a long hike near the Dead Sea with the leader of the competing group.
