Scientists discover traces of the Milky Way collision with another galaxy

Scientists obtained for the first time a direct observational proof of the presence of dark matter in the innermost part of our Galaxy, the Milky Way

UNITED STATES (VOP TODAY NEWS) – Scientists have discovered traces of the collision of the Milky Way, which is part of the solar system, with another galaxy, reports

Astronomers from Columbia University in New York spent a billion measurements of the movements of stars and found about 33 thousand luminaries that are within our galaxy, but not moving like most other stars.

Six hundred of these “wrong” stars were placed under special observation with telescopes.

The results confirmed the assumption that these stars appeared within the Milky Way about 10 billion years ago as a result of a collision with another galaxy.

The astronomers named the Gaia-Enceladus hypothetical galaxy. It is assumed that it was five times smaller than the Milky Way and this is the first confirmation that in the past the Milky Way absorbed not only dwarf, but also large galaxies.

The diameter of the Milky Way galaxy is estimated at 100-200 thousand light years. It has, according to various sources, from 200 to 400 billion stars. A number of scientists believe that in 4 billion years the Milky Way will collide with the Andromeda galaxy.
