Hubble Space Telescope shows us what happens when two galaxies collide. That’s concerns to our Milky Way galaxy because our own galaxy is waited for collide with the next-door Andromeda galaxy in about four billion years.
The image, in the constellation of Hercules, draws a scene about 230 million light-years away from the Earth. Here, Hubble zooms in on the inosclating galaxies, a double object named as NGC 6052.
When NGC 6052 was first cataloged by William Herschel in 1784, it was classified as a single, irregular galaxy with a weird shape. But now we know the shapes are strange, because the two galaxies come together.
Scientists are working to better understand galactic evolution and to explore mergers such as the NGC 6052 and to get an idea of what our own collision would look like a few billion years later. Galactic mergers are very common in the universe; For example, we know that Andromeda ate one of the brothers of the Milky Way long ago. The Milky Way-Andromeda collision is not expected to pose any threat to Earth because the distances between individual stars in galaxies are very wide, but scientists are still interested in the mechanics of how these interactions take place.
