A massive migration of more than 100 gas clouds out of the center of the Milky Way and toward the outer space of the galaxy receives great attention from scientists.

These gas clouds contain much hydrogen.

Specifically, a group of researchers led by Lockman, McClure-Griffiths, and Enrico DiTeodoro, together with the Australian National University, discovered a large migration of more than 100 gas clouds coming out of the center of the galaxy. Milky Way and towards the outer space of the galaxy.

These contain a lot of Hydrogen, which moves out of the center of the Milky Way at a speed of 400km / s towards the outer edge of the space.

Explaining this migration, experts believe that the edge is having a tremendous source of nuclear wind, forming and sucking up a cloud of gas from the center out.

The purpose of this migration is to accrue, set up a small cone-shaped rim with expansion materials available.

It is estimated that this cone disk area is 5,000 light-years away from the center of the Milky Way.
