Winds surrounding black hole are fastest on record
When visiting the center of a galaxy nicknamed J0230, pack a sturdy windproof jacket. There, you will encounter a galactic hurricane with winds whipping at about 200 million kilometers per hour. At that speed, nearly 20 percent of the speed of light, a trip around Earth would take just 0.7 seconds. These are the fastest known winds around a quasar, a blazing disk of detritus around a supermassive black hole, researchers report in the March 21 Monthly Notices of the Royal Astronomical Society. They’re about 625,000 times as fast as the highest sustained winds in any hurricane seen on Earth.
These quasar winds get their speed from the intense radiation emitted by the disk, which glows as bright as roughly 22 trillion suns. The light comes from gases slamming together as they orbit a black hole with 2.2 billion times as much mass as the sun. Despite occupying a relatively tiny volume of
