Scientists Find Ancient Black Hole That Grew Up Too Fast
A flickering quasar from 12.9 billion years ago shows how quickly black holes formed in the early universe.
Scientists have made an exciting discovery about black holes in space. They found a special quasar that existed 12.9 billion years ago, when the universe was very young. This quasar flickers like a candle flame, getting brighter and dimmer in a pattern scientists had never seen before. The discovery shows that black holes grew much faster in the early universe than anyone expected.
A quasar is like a giant cosmic lighthouse powered by a supermassive black hole. These black holes sit at the center of galaxies and eat gas and dust around them. As the material falls toward the black hole, it gets extremely hot and glows brightly. Some quasars shine with the light of trillions of suns, making them some of the brightest objects in the universe.
The team of scientists used data from NASA's NEOWISE space mission to make their discovery. NEOWISE spent 14 years scanning the sky and taking pictures of space. The scientists had to look through all this data to find the flickering quasar. It was like finding a special twinkling star among billions of other lights in the sky.
What makes this quasar so special is how organized it appears to be. The gas around the black hole has formed a flat, pancake-shaped disk. For such a young quasar, this is very surprising because scientists expected the gas to be messy and puffy. This organized structure suggests the black hole grew up much faster than scientists thought possible.
We saw the quasar flickering randomly over the 14-year period, much like a candle's flame flickers without a fixed pattern.
