The Original Shape of the Black Hole Succeeds in Photos


On Wednesday scientists launched a photo of the first black hole, this photo shows a silhouette of a black hole and a bright ring that forms when light bends in strong gravity around a black hole. The photo is a product of observations carried out in April 2017 by the Event Horizon Telescope (EHT), an international consortium that connects eight radio observatories around the world to make an Earth-sized telescope with enough power to see what until now has not seen.

                             The black hole was found in the M87 galaxy which is located about 55 million light years from Earth in the constellation Virgo. Unlike the amazing Milky Way spiral, M87 is a giant elliptical galaxy that is blobby. Scientists target two very large black holes. The first black hole named “Sagittarius A”, located at the center of the Milky Way Galaxy. Sagittarius A measures four times the mass of the sun, a distance of 26,000 light years from earth. The distance of one light year reaches 9.5 trillion kilometers. The second black hole, named M87, is located near the center of the Virgo Galaxy, measuring 3.5 billion times the distance and 54 million light years away. This black hole has an area of 40 billion kilometers, or 3 million times larger than Earth and larger than the solar system. we. The researchers call the black hole a ‘monster’. The distance of the black hole is 500 million trillion kilometers from Earth.

Black holes are some of the strangest and most interesting objects found in space. They are objects with extreme density, with a very strong gravitational pull so that light cannot escape their grasp if close enough. Albert Einstein first predicted black holes in 1916 with his general theory of relativity. The term “black hole” was created in 1967 by American astronomer John Wheeler, and the first was discovered in 1971. There are three types: star black holes, supermassive black holes and medium black holes. Star black holes When a star burns its last fuel , it can collapse, or fall into itself.

For smaller stars, up to about three times the mass of the sun, the new nucleus will become a neutron star or white dwarf. But when a larger star collapses, it continues to compress and create star black holes. Black holes formed by the collapse of (relatively) small, but very dense individual stars. Such objects pack three or more solar masses into the size range of the city. This causes a large amount of gravitational force to attract objects around it.

Black holes eat dust and gas from the surrounding galaxies, grow in size. According to the Harvard-Smithsonian Center for Astrophysics, “the Milky Way contains several hundred million” star black holes. Supermassive black holes Small black holes fill the universe, but their cousins, black holes supermassive, dominating. Supermassive black holes are millions or even billions of times the size of the sun, but have fingers similar to the closest stars to Earth.

Such black holes are thought to be located in the center of almost every galaxy, including the Milky Way. Scientists are not sure how the big black hole appears. Once they are formed, they collect masses of dust and gas around them, materials that are abundant in the center of the galaxy, which allow them to grow to very large sizes.

Medium black holes Scientists have thought black holes come only in small and large sizes, but recent research reveals the possibility of the existence of medium, or medium size black holes. Such bodies can form when stars in clusters collide in a chain reaction. Some of these formed in the same region can eventually fall together in the center of the galaxy and create supermassive black holes. History of the Black Hole
