We Could Be Just Days Away From Seeing the First-Ever Photo of a Black Hole
Lots of people have created simulations and illustrations of black holes based on what is currently known about these incredibly dense objects, but to date, the public has never seen an actual picture of one.
As NBC News reports, that could change next Wednesday, when a team of international scientists releases the “groundbreaking result” of a project that has set its sights on capturing the first image of a black hole. Six simultaneous press conferences will be held around the world, and the U.S. announcement in Washington, D.C. will be livestreamed starting at 9 a.m. on April 10.
The reason black holes are so hard to see is because no light can escape from them. However, scientists know they exist because of the gravitational pull they exert on nearby objects, including stars and gas. The latest endeavor to observe a black hole, dubbed the Event Horizon Telescope (EHT) project, has built a “virtual Earth-sized telescope” by creating a network of eight radio observatories around the world.
It is believed that the announcement will concern a supermassive black hole at the center of the Milky Way called Sagittarius A* (pronounced “Sagittarius A-star”). If scientists are successful in capturing an image of the distant black hole, it would be the equivalent of “standing in New York and counting the individual dimples on a golf ball in Los Angeles,” according to an EHT video.
As for what Sagittarius A* might look like, that remains to be seen. “We might see a crescent, brightened on one side—or a bipolar, jet-like structure,” Dan Marrone, an experimental astrophysicist at the University of Arizona, told Mental Floss in 2017. “We honestly don’t know.”
