A "Dense Bullet of Something" Blasted Holes in the Milky Way

Bullet Holes

Scientists say that something mysterious punched gigantic, cosmic "bullet holes" in parts of the Milky Way.

There's a string of holes in a long stream of stars called GD-1 that suggests that some yet-undiscovered thing blasted its way through, according to research presented to the American Physical Society last month. Harvard-Smithsonian astrophysicist Ana Bonaca, the scientist who discovered the cosmic crime scene, suspects that the gigantic bullet holes may have been carved out by invisible dark matter.


to have gotten away with it – Bonaca told Live Science that is the evidence of the crime scene beyond the size of the gaps in the stellar stream.

luminous object that we have observed, "Bonaca duty Live Science . “It's much more than a star… Something like a million times the mass of the Sun. So there are just no stars of that mass. We can rule that out. And if it were a black hole, it would be a supermassive black hole of the child we found at the center of our own galaxy. ”

Dark Hammer

Because there is no evidence of such a black hole, Bonaca suspects a ball of dark matter may have crashed through the stars. But it's too early to rule out any possibilities.

"It's a bullet of something," Bonaca said.
