Irish filmmaker Seán Doran has a habit of putting together glorious-looking YouTube videos that reach into the glorious vistas of space. Just this month he put together a stunning video of Mars .
Now he's posted a video of an "Earthrise."
What's an Earthrise? It's much like a sunrise, only instead of watching the sun stretch above the Earth's horizon, this time we're watching Earth itself rise, from the perspective of the moon.
It's mind-blowing to watch. And a good exercise in reminding yourself that Earth isn't at the center of this universe, or any universe for that matter.
The very first Earthrise images were taken by NASA's Apollo 8 mission in December 1968.
