Black holes are some of the most enigmatic objects in the universe. This is partially because the equations of general relativity that we use to understand them break down when studying black holes’ ultra-dense centers. However, a new paper shows how astronomers could one day overcome this challenge by using gravitational waves to “see” inside … Read more
Astronomers have spotted a black hole mysteriously spewing up chunks of a devoured star several years after consuming it. The event, which scientists have classified as AT2018hyz, began in 2018 when astronomers saw the black hole ensnare a hapless star in its strong gravitational pull before shredding it to pieces. Then, three years later, in … Read more
Two of the strangest, most colossal structures in the Milky Way may have formed in a 100,000-year-long explosion at our galaxy’s center, new research suggests. Those structures — named the Fermi bubbles and eROSITA bubbles after the respective telescopes that discovered them — straddle the Milky Way’s center in an enormous hourglass shape, with one … Read more
