The universe is expanding, pushing the galaxies inside it apart like raisins in rising bread dough. This indicates that one day, in the far future, those who live in our galaxy will not be able to spot any other galaxies visible in the night sky. That doesn't imply galaxies in close proximity don't interact. The Andromeda and Milky Way galaxies interact gravitationally with one other, just as Earth's gravity would tug on a nearby asteroid, setting it on a collision course with our planet. Because of this, the two galaxies are now approaching each other at a speed of around 37 miles per second. Does this mean the two galaxies will crash into each other? What will become of mankind if this happens? In this video, we delve into scientists' shocking revelation that the Andromeda galaxy is already crashing into our own galaxy!
If you look up into the northern night sky between Cassiopeia’s “W” asterism and the Great Square of Pegasus, you will find the constellation Andromeda. The star pattern was dubbed after the Greek hero Perseus' wife, the fabled princess Andromeda. The constellation was initially catalogued in the second century by the Greek astronomer Ptolemy, and it is also known as Chained Maiden, Persea, or Cepheis. The Andromeda constellation is also home to various other deep sky objects. Andromeda is positioned outside the galactic plane and does not include any Milky Way clusters or nebulae; however, it does contain other observable galaxies. The most well-known of these galaxies is, of course, the Andromeda Galaxy, which gets its name from the large constellation. It is one of the most well-known objects in the sky visible with the naked eye. Our closest neighboring galaxy is also known as Messier 31 or M31. The name was inspired by Charles Messier, a French astronomer who catalogued the massive galaxy.
