Dark matter is believed to make up more than 80 percent of all matter in the universe, but what it actually is remains a mystery.

Now, astronomers have found something that gives us a major clue.

In a pair of new studies published in Nature Astronomy and Monthly Notices of the Royal Astronomical Society, the astronomers report that they’ve found a low mass object in the ancient outskirts of the cosmos by examining the gravitational distortions in the light of a much larger galaxy.

This oddity, they claim, is the lowest mass object ever found using this technique, which is called gravitational lensing.

“It’s an impressive achievement to detect such a low mass object at such a large distance from us,” Chris Fassnacht, an astronomer at the University of California, Davis, and co-author of
