They find a "dense" object, equivalent to one million suns, causing a hole in the Milky Way

An unknown "massive and dense" object has pierced the longest current of our galaxy, GD-1, with a huge hole, says one American researcher at the Harvard-Smithsonian Center for Astrophysics (USA).

The scientist Ana Bonasa presented her findings at the recent American Physical Society conference in Denver, the agency said.

He explained that star currents are lines of stars that move together through galaxies. Under normal conditions, they have almost the same density, but the scientist has discovered a "likely place of disruption" in one of these structures.

"Morphology in the sky implies a recent and close collision with a disturbing subject, massive and dense," Bonasa says in a summary of his work.

What causes the hole?

It is not clear, however, what exactly caused the hole. – We can not treat it [el impactador] to any light object we've seen, "said LiveScience astrophysicist.

First, the object is "much more massive" than a star, "something like a million times the mass of the Sun," explains Bonasse, adding that "there are just no stars at this table," so you can reject this hypothesis.

On the other hand, if it was a black hole, "it would be a supermassive black hole of the sort we find at the center of our own galaxy," he said.

Since there are no signs of a supermassive black hole in the neighborhood, Bonak points to the ball of dark matter as a "plausible candidate."

If true, this would be an exciting discovery for scientists, as this would enable them to study the elusive dark matter. However, the researcher admits that it is too early to exclude any other possibility.

"This may be a light object that has disappeared somewhere and is hiding somewhere in the galaxy," says Bonasse, concluding that "it's a bullet of something." / JML
