"We know the Milky Way has some 60 confirmed companion satellite galaxies, but we think there should be dozens more of these faint galaxies orbiting around the Milky Way at close distances," said Isabel Santos-Santos, the lead researcher at Durham University's Institute for Computational Cosmology, in a statement.

Our Milky Way could have many more satellite galaxies than we've detected so far. They're just too faint to be seen.

Researchers may have found our galaxy's missing companions, further bolstering science's most widely accepted cosmological model.

Scientists predict up to 100 invisible galaxies may orbit the Milky Way, hiding just beyond our current detection limits.

New simulations suggest that dozens of ultra-faint “ghost” galaxies may be orbiting the Milky Way, hidden from current surveys.
