The objects are infinitely dense, as if compressing the mass of the Earth to the size of a coin. It’s hard to imagine the concept of black holes. It is so bizarre that time can stop abruptly in it. So powerful that it can tear the stars apart. It is so strong that even the light cannot escape. Like an infinite gravity well, they represent a region of spacetime where so much mass is condensed into such a tiny space that gravity overcomes all known forces. The secrets of black holes are very deep. Black Holes: The Hurried Engines of our Universe This is the age when Moore’s law, machine learning and, finally, quantum computers can discover one of the most amazing and mysterious objects in the Universe. These two images, equally blurry but no less important, are part of the golden age of the “new astronomy”. Just a few months ago, the same team showed the long-awaited second image of a black hole in the center of our Galaxy. Black holes are voracious beasts that are among the most magical objects in space that are very difficult to photographĮverything changed in 2019, when a group of scientists combined several important points: proven astronomy techniques, excellent global cooperation and advances in data storage and computing to create the first ever image of a black hole. This is just a rough illustration of what they might look like, based on mathematical theory and fairly recent evidence for the existence of black holes. "Although we cannot see the black hole itself, because it is completely dark, glowing gas around it reveals a telltale signature: a dark central region (called a 'shadow') surrounded by a bright ring-like structure," the EHT team said in its announcement.Almost every image of a black hole that we have seen is not a photograph. To obtain the image, scientists used observations from April 2017, when all eight observatories were pointed at the black hole. More than 300 researchers collaborated on the effort to capture the image, compiling information from radio observatories around the world. It took several years to refine our image and confirm what we had, but we prevailed." "What made it extra challenging was the dynamic environment of Sgr A*, a source that burbled then gurgled as we looked at it," Özel said, "and the challenges of looking not only through our own atmosphere, but also through the gas clouds in the disk of our galaxy towards the center. Putting the size of the black hole into an Earthling's perspective, the team said that seeing it from the surface of our planet would be like trying to spot a donut on the moon. Now they have a direct view of what Feryal Özel, a professor of astronomy and physics at the University of Arizona, called the "gentle giant" itself. In the case of Sgr A*, scientists have previously observed stars orbiting around the Milky Way's center. But scientists have been able to detect and study them based on the powerful effects they exert on their surroundings. Its mass is about 4 million times that of the sun, and it's about 27,000 light years from Earth, according to MIT.īlack holes have long been a source of public fascination, but they also pose notorious challenges to researchers, mainly because their gravitational fields are so strong that they either bend light or prevent it from escaping entirely. The black hole is often referred to as Sgr A*, pronounced sadge ay star. "It's the dawn of a new era of black hole physics," it added. "We finally have the first look at our Milky Way black hole, Sagittarius A*," an international team of astrophysicists and researchers from the Event Horizon Telescope team announced on Thursday. "It's the dawn of a new era of black hole physics," the Event Horizon Telescope team said as it released the first-ever image of supermassive black hole in the center of the Milky Way.įor years, the supermassive black hole in the dark center of the Milky Way galaxy has been theorized about and studied - and finally, it's been captured in an image.
