For the first time, scientists have discovered planets in galaxies beyond the Milky Way.
Using data from NASA’s Chandra X-ray observatory, a team of astrophysicists from the University of Oklahoma identified the extragalactic planets about 3.8 billion light years away.
The space observatory helped scientists find about 2,000 objects with comparable mass to the Moon and Jupiter.
The Oklahoma University team used a technique called microlensing, which identifies the gravitational signature of planets orbiting extremely distant stars.
“We are very excited about this discovery.
This is the first time anyone has discovered planets outside our galaxy,” said Oklahoma University professor Xinyu Dai, in a statement.
