Our Galaxy Is on a Collision Course. And It’s Not the First Time

Taking place in the next few billion years is a cosmic event that will change all that are still living within the two galaxies. The Milky Way Galaxy and the Andromeda Galaxy are on a collision course that will take millions of years to complete. It will start around 2 billion years from now. There is another one that we have recently found and that is the Triangulum. That will occur within the next 4 billion years.

Key Takeaways:

• Stars move around at an extremely fast pace and it’s so fast that humans can barely see it.
• The Milky Way drives more than 100 galaxies around with those galaxies known as the Local Group.
• The only galaxy bigger than the Milky Way within the Local Group is known as the Andromeda Galaxy.

“Galaxies swing around one another, slowly spiraling together until they merge.”
