Anyone who has ever seen a night sky time lapse video knows it can be one of the greatest combinations of technology and photography.
As kids we all laid down on the ground and gazed at the night sky. No matter how long we looked up, though, nothing ever seemed to move. That's not the case in night sky time lapse videos, which show how much movement there is in the night sky.
In Arrow of Time: Milky Way Time Lapse Collection, Harley Grady creates a time lapse of the night sky using more than 20,000 single images taken over the course of three years. The result is magical, reminding us how beautiful the night sky can be.
