Just a short while ago, I showed you how the most powerful telescopes were able to gather incredible amounts of light from a tiny part of the sky, and peer deeper into the darkest regions of the Universe than ever before. But there’s another way to do astronomy that’s just as majestic: view the entire sky at once.
For an astronomer, this is easy; all you have to do is get a fisheye lens, and you can see an entire hemisphere with no problem. (The “up” hemisphere is much more interesting than the “down” one.) If you use it at night and take a time-lapse exposure, you can truly create some amazing images of the entire night sky, like this one by Alan Dyer.
But last month, a group of amateur astronomers got together in Fort Davis, Texas, and created this time-lapse video at a star party of the Milky Way galaxy rising as the night progressed. It is stunning how beautiful something as simple as the Earth spinning can be. Watch the entire 11 hour night compressed into 48 seconds; you will not be sorry!
