The Webb Space Telescope has discovered the earliest known merger of black holes.
These two gigantic black holes and their galaxies consolidated just 740 million years after the universe-forming Big Bang. It's the most distant detection ever made of merging black holes, scientists reported Thursday.
One black hole is 50 million times more massive than our sun. The other is thought to be similar in size, but is buried in dense gas, which makes it harder to measure.
Until now, astronomers weren鈥檛 sure how supermassive black holes got so big.
The latest findings, published in the Monthly Notices of the Royal Astronomical Society, suggest mergers are how black holes can grow so rapidly 鈥 鈥渆ven at cosmic dawn,鈥 said lead author Hannah Ubler of the University of Cambridge.
"Massive black holes have been shaping the evolution of galaxies from the very beginning," Ubler said in a statement.
Launched in 2021 as the eventual successor to NASA's Hubble Space Telescope, Webb is the biggest and most powerful observatory ever sent into space. A joint U.S.-European project, the infrared observatory surveys the universe from a location one million miles (1.6 million kilometres) from Earth.
