Scientists have for the first time confirmed the merger of two highly eccentric black holes. Egg-shaped eccentric orbits form when two black holes spiral towards each other and collide under each other’s strong gravitational influence. Therefore, highly eccentric orbits may suggest black holes repeatedly snack on other black holes in densely populated areas, like the … Read more
New Year’s Day comes around once every 47.5 hours on the roughly Neptune-sized exoplanet TOI 674b, which makes it something of a rare creature. In spite of years of hunting, surprisingly few middle-sized gas giants have ever been seen with orbits shorter than a few days in length, creating what astronomers refer to as a … Read more
In 2014, amateur astronomers in New Zealand glimpsed a flare of light emanating from the constellation of Centauri. NASA later confirmed this blaze was a massive supernova explosion from another galaxy an incredible 57 million light-years away from our Milky Way. “Dedicated amateur astronomers often make intriguing discoveries – particularly of fleeting astronomical phenomena … Read more
In the heart of the Milky Way, stars tread a complex measure. Bound by the gravitational field of the supermassive black hole in the galactic center, Sagittarius A*, a group of stars known as S-stars swoop on wild, years-long orbits. These orbits were recently studied to measure Sgr A*, a result that won the scientists … Read more
