Nearly every star and galaxy that you can observe is red-shifted and so is moving away from you. The closest large galaxy to us is blue-shifted and will collide with the Milky Way in 5,000,000,000 years.
What is the name of that galaxy?
Andromeda
This is being caused by my 1st period.
Our Milky Way is on a collision course with another spiral galaxy called Andromeda. Today Andromeda is visible as a speck of light in the night sky, but about 5 billion years from now, it will be tangled up with us. Our galaxy's spiral arms will disappear, and so will our supermassive black hole.

A. billions of years
