Its pockmarked surface may seem timeless, but the truth is our moon hasn’t always looked the way it does today.
To get a sense of how Earth's only natural satellite has changed -- and the violent forces that caused the changes -- have a look at this magnificent GIF (below) that was recently posted to Reddit by Redditor mike_pants.
A sped-up version of a 2012 NASA video, the GIF compresses the moon's 4.5-billion year evolution in just 30 seconds.
The GIF has been seen more than 2.5 million times since it was uploaded. If you haven't seen it yet, it's definitely worth a look.
How exactly did the moon form in the first place? For the answer, check out the "Talk Nerdy To Me" video below.
