Scientists on Wednesday revealed the first image ever made of a black hole, depicting a fiery orange and black ring of gravity-twisted light swirling around the edge of the abyss.
The picture, assembled from data gathered by eight radio telescopes around the world, shows the hot, shadowy lip of a supermassive black hole, one of the light-sucking monsters of the universe theorized by Einstein more than a century ago and confirmed by observations for decades. It is along this edge that light bends around itself in a cosmic funhouse effect.
“We have seen what we thought was unseeable. We have seen and taken a picture of a black hole. Here it is,” said Sheperd Doeleman of Harvard, leader of a team of about 200 scientists from 20 countries.
University of Waterloo physicist Avery Broderick, a co-discoverer, declared: “Science fiction has become science fact.”
In fact, Jessica Dempsey, a co-discoverer and deputy director of the East Asian Observatory in Hawaii, said the fiery circle reminded her of the flaming Eye of Sauron from the “Lord of the Rings” trilogy.
Unlike smaller black holes that come from collapsed stars, supermassive black holes are mysterious in origin. Situated at the center of most galaxies, including ours, they are so dense that nothing, not even light, can escape their gravitational pull. This one’s “event horizon” — the precipice, or point of no return, where light and matter begin to fall inexorably into the hole — is as big as our entire solar system.

Instagram Makes Teen Accounts Private as Pressure Mounts on the App to Protect Children- Instagram is making teen accounts private by default as it tries to make the platform safer for children amid a growing backlash against how social media affects young people's lives.
Instagram is making teen accounts private by default as it tries to make the platform safer for children amid a growing backlash against how social media affects young people's lives. The teen accounts will be private by default. Private messages are restricted so teens can only receive them from people they follow or are already connected to. Sensitive content, such as videos of people fighting or those promoting cosmetic procedures, will be limited, Meta said. Teens will also get notifications if they are on Instagram for more than 60 minutes and a sleep mode will be enabled that turns off notifications and sends auto-replies to direct messages from 10 p.m. until 7 a.m.
