“Lactometha”: Astronomers predict a collision between the Milky Way and Andromeda

The image resembles Orp 195, a cluster of three galaxies located 389 light-years from Earth in the Lynx galaxy, and its members ‘tear’ each other in three different gravitational battles. One rule that astronomers predict is that the Milky Way, 4.5 billion years later, will collide with the neighboring Andromeda galaxy and its satellite galaxy. The picture was taken by a senior space telescope two weeks after a close break to take service permanently at the end of June. This is how he reconsidered it ABC.

The Milky Way is one of the three largest galaxies in our environment. Along with Andromeda and the triangular galaxy (M31 and M33), the galaxy we live in has a good portion of the mass known as the local group, which consists of thirty galaxies that travel together in space.

Because of their enormous gravitational pull, the two giants of the group, Andromeda and the Milky Way, are destined to collide one day, which will completely change our cosmic environment. When that happens, in about 4.5 billion years, the two galaxies will merge into a single, larger one, which astronomers have already named ‘Lactometha’.

However, the three-dimensional motions of galaxies within the local group were not clear until recently, which did not allow us to know many details about future collisions.

Roland van der Marrell, author and lead author of the Baltimore Space Telescope Science Institute in the United States, said: We are now able to do this using the package. ‘
