Scientists say that something mysterious has hit gigantic, cosmic "bullet holes" in parts of the Milky Way.
In a long circle of stars called GD-1, there are a number of holes that indicate that an undiscovered thing has been blown up, according to research released to the American Physical Society last month.
Harvard-Smithsonian astrophysicist Ana Bonaca, who discovered the cosmic crime scene, suspects that the gigantic "bullet holes" were unearthed by invisible dark matter.
Unfortunately, the culprit of this celestial shooting seems to have gotten away with it – Bonaca told Live Science that at the scene there is no evidence beyond the size of the gaps in the stellar stream.
"We can not assign [the impactor] to any luminous object that we have observed." Bonaca told Live Science.
"It's much more massive than a star … About a million times the mass of the sun, so there are just no stars of this mass, we can rule that out, and if it were a black hole, it would be a supermassive black Hole, as we find it in the center of our own galaxy. "
With no indication of such a black hole, Bonaca suspects that a sphere of dark matter might have crashed through the stars. But it is too early to definitely rule out all possibilities.
"It's a dense sphere of something," said Bonaca.
