A Surprise in the Night Sky: A Small Black Hole's Big Punch

You know how we thought the strongest gamma rays in the universe came from supermassive black holes far, far away? Well, scientists just found a tiny black hole nearby that's giving those giants a run for their money!
This little powerhouse is called V4641 Sagittarii. It's a binary system, meaning it's two stars orbiting each other. One of them is a black hole that's six times heavier than our Sun. The other star is three times heavier than our Sun, and the black hole is eating it alive!
As the black hole munches on its companion, it spits out radiation like a tiny cosmic cannon. And get this—the radiation is so strong, it's 200 trillion times more energetic than visible light! That's like comparing a firecracker to a nuclear bomb.
Scientists were shocked because they thought only supermassive black holes in distant galaxies could produce such powerful gamma rays. But here we have a tiny microquasar, right in our own galaxy, doing the same thing.
A team of scientists used a powerful observatory called HAWC to spot this cosmic oddball. HAWC has a wide-angle view and can map two-thirds of the sky every day. That's how they found V4641 Sagittarii, glowing with energy that broke all the rules.
This discovery is a big deal because it means even small black holes can act like extreme energy accelerators. It also lets scientists study cosmic processes that normally take millions of years in just a few days or weeks.
So, the next time you look up at the night sky, remember that even the smallest things can pack a mighty punch.
