These super-scary Black Hole facts just got revealed!
No matter how much we already know about these scary Black Holes from which nothing, not even light can escape, mysterious new findings around these freaks of nature never ends! Now, a team of astronomers from the University of North Carolina at Chapel Hill has found a previously overlooked treasure trove of massive black holes that exist in dwarf galaxies. These offer a glimpse into the origin of the supermassive black hole at the centre of our own Milky Way galaxy, Carolina Graduate School magazine reported. You can read the report here. According to the research findings, these supermassive black holes came about after thousands of dwarf galaxies merged to create giant spiral galaxies like the Milky Way.
A black hole is a region in space where gravity is so strong that even light cannot escape. Because everything has been squeezed into such a small space, gravity is incredibly strong and that keeps anything from escaping from a black hole. According to NASA, black holes origin starts from a dying star. It added, "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."
People cannot see black holes because no light can escape. They are undetectable. Space telescopes equipped with specialised equipment help in the discovery of black holes. Only special instruments can see how stars that are near black holes behave differently from other stars. Though, you would be surprised to know that Black holes can be big or small. Even NASA scientists think that the smallest black holes are as small as just one atom! While the largest black holes are called "supermassive."
