Researchers reveal two secrets of an ancient galaxy. One of the oldest known galaxies holds a secret at its center.
Another discovery could provide clues to the very first stars in the universe. The galaxy GN-z11 was discovered by the Hubble Space Telescope in 2016. It already existed 430 million years after the Big Bang, with which the universe began 13.8 billion years ago. The newly discovered supermassive black hole at the center of the galaxy is the most distant active black hole discovered to date.
