Astronomers have spotted some kind of outer space rock that’s the first visitor from outside of our solar system that they’ve ever observed.

The discovery has set off a mad scramble to point telescopes at this fast-moving object to try to learn as much as possible before it zips out of sight.

“Now we finally have a sample of something from another solar system, and I think that’s really neat, ” says Karen Meech, an astronomer at the University of Hawaii Institute for Astronomy, “and so you’d love to see if it looks like stuff in our solar system.”
