According to new research, the home of all life, as we know it, the Milky Way Galaxy is on a "collision course" with its space neighbor Andromeda. But you don't have to worry, astronomers say, it's not going to happen for about 4.5 billion years.
The study noted that the size of Andromeda, much larger than the Milky Way, most likely makes it a "cannibal" neighbor, swallowing more.
"The Milky Way went through a collision with Andromeda in about four billion years. So knowing what monster our galaxy is up against is useful for figuring out the ultimate fate of the Milky Way, "said Australian National University researcher Dougal McKee in his statement.
" Andromeda has a much larger and more complex star, than the Milky Way, which indicates that it can cannibalize many more galaxies, perhaps larger ones, ”McKee added.
McKee and other researchers used five telescopes to make their observations, noting that at least two clusters of stars were orbiting Andromeda. one or the rest of the galaxy.
"We interpret these individual cluster populations as emerging from two major eras of accretion, probably separated by billions of years," the study notes.
The 92-star clusters that were previously identified were located on 81,000 light-years away from the center of Andromeda. Of the 92 clusters, 77 were in one group, moving perpendicular to the galaxy's disk, and the other group orbiting at 90 degrees.
i managed to vi to create the way Andromeda painted them and eventually to cover them at different times, "said McKee.
The study was published in the scientific journal Nature
