Astronomers studying information gathered by the Hubble Space Telescope have concluded that dark matter, the elusive glue that holds the universe together, barely interacts even with itself.

When clouds of gas collide in space, they typically slow down or stop moving completely. Dark matter, on the other hand, continues to glide harmlessly through other other dark matter.

Although dark matter may now seem more enigmatic than ever, researchers point out that the discovery will help further our understanding of dark matter's properties.

"There are still several viable candidates for dark matter, so the game is not over, but we are getting nearer to an answer," explains lead author Dr. David Harvey in a news release. "These 'Astronomically Large' particle colliders are finally letting us glimpse the dark world all around us but just out of reach."
