There's a monster at the centre of our galaxy.
There's a monster at the centre of our galaxy. Not a metaphor — an actual supermassive black hole called Sagittarius A*, packing the mass of roughly four million Suns into a single point in space. Gravity there is so extreme that light itself cannot escape once it crosses the edge. For decades it was detectable only by its influence on surrounding stars, which whip around it at extraordinary speeds. Then in 2022, something remarkable happened: astronomers stitched together data from radio telescopes across the entire planet and produced an actual image of its shadow — a dark absence ringed by glowing gas. Our own cosmic address has one of these at its heart. So does nearly every large galaxy we know of. Follow Deep Field Vault for more of the universe, one true fact at a time.
