![]() Chandra’s scientists have stated that to turn the Earth into a black hole, we would have to contract its entire mass to such an extent that it would become the size of a marble. In order to turn Earth into a black hole, we would have to compress all its mass into a region the size of a marble. This is how a black hole is born – the most “hungry” object in the Universe, greedily absorbing matter around it. And since the collapse causes a strong compression of the star, its gravity becomes so strong that even light cannot leave it. After the collapse, a supernova flare occurs, which sends parts of the star into outer space. Kornmesser Just Contract the Earthīlack holes, as we know them, are extremely dense objects that form after the collapse of a star under the influence of its gravity after its fuel is exhausted. Supermassive black hole in the artist’s image. NASA’s Chandra Observatory joined the event and fantasized a bit about how we can turn the Earth into a black hole. During the event, the agency covered their secrets and shared scientific revelations. Supernova – n.NASA devoted the entire last week from May 2 to May 6 to the mysterious and frightening objects of the Universe – Black Holes. _ Words in This StoryĪround the corner – phr.

The Associated Press and Reuters reported on this story. “If you find an ant while scanning a tiny fraction of your kitchen, you know there must be many more out there.” “It is most likely that there are black holes much closer than this one,” he told the AP. But in a few million years the closer star is expected to grow as part of its life cycle.Īvi Loeb is director of Harvard’s Black Hole Initiative. Rivinius said the two stars are far enough away from the black hole that it is not pulling material from them. About 15 million years ago, one of the stars got too big and too hot and went supernova, turning into the black hole in a violent process, he added. They may be 140 million years old, but at 15,000 degrees Celsius, they are three times hotter than the sun. Rivinius said these are young, hot stars compared to our 4.6 billion-year-old sun. “It will motivate additional searches among bright, relatively nearby stars,” said Ohio State University astronomer Todd Thompson. Other astronomers say the theory makes sense. They decided it could only be a black hole. They say their telescope observations confirmed that there was an object about four times the mass of our sun pulling on the inner star. Astronomers think most black holes remain unseen because they do not have anything close enough to swallow up.Īstronomers found the new one because of the triple system formation. Scientists can only find them when they are eating away at parts of a partner star or something else falls into them. It sits in the constellation Telescopium in the sky’s Southern Hemisphere.Īstronomers theorize there are between 100 million to 1 billion of these small but dense objects in the Milky Way. The newly discovered black hole is gravitationally attached to two stars in a so-called triple system, the researchers said. That black hole is four million times the sun’s mass. Some are huge, like the one at our galaxy’s center 26,000 light years from Earth. Rivinius said the next closest black hole to Earth is probably about three times further, about 3,200 light years away.īlack holes are extremely dense objects with gravitational pulls so powerful that not even light can escape. But he noted that in terms of the universe and the galaxy, we should consider the new find “just around the corner.” In an interview with Reuters news agency, he admitted the black hole is still very far from Earth. Thomas Rivinius led the research for the European Southern Observatory. The research recently appeared in the publication Astronomy & Astrophysics. They found the black hole using a telescope based in Chile. The discovery was made by researchers from the European Southern Observatory. A light year is the distance light travels in a year, about 9.5 trillion kilometers. It sits about 1,000 light years from Earth. The black hole is believed to be at least 4.2 times the mass of the sun. European astronomers say they have found the closest black hole to Earth ever discovered.
