NASA Releases a Time-Lapse One Year and One Million Miles in the Making

NASA's aptly named EPIC (Earth Polychromatic Imaging Camera) camera sits about one million miles from our planet, where it uses an array of sensors to monitor and provide observations of cloud heights, aerosols, vegetation growth, and the state of ozone in the atmosphere. It also provides some pretty neat images of Earth, which NASA has assembled into a year-long time-lapse.

EPIC sits aboard the DSCOVR (Deep Space Climate Observatory) satellite at Lagrange Point 1, a point at which the sun's gravity is essentially canceled out by the Earth's gravity. This allows it to remain in place essentially unassisted and also gives it a view of the Earth that is always illuminated, allowing scientists to collect imagery 24 hours a day. The camera uses a four-megapixel CCD sensor that records series of images taken through 10 different narrowband filters across the light spectrum, from which the red, blue, and green filters are used to create the natural color images you see above. 

If you watch carefully, you'll see the Earth change tilt over the course of the year. You can also see the moon's shadow cross the Earth during a total solar eclipse. If you're a fan, you can see EPIC's most recent images here. Science is awesome.

Hey guys, looks like a bartender shaking a drink.
Why not slow it down so we can actually see something?
As it is you have a good way to induce vertigo, motion sickness and vomiting.

If you’re experiencing vertigo, motion sickness and vomiting from watching this, I suggest a trip to the emergency ward. Maybe you swallowed some cleaning product or something.

The earth is not that green anymore... I need to leave Dubai and start appreciating the greens again in my home country :(

Interesting video but the narrator is not very good. They should have gotten a voice actor.
I was honestly thinking that the world would be a bit more green than it is. :(

Where's the Stars?

The proper exposure for Earth makes the stars too dark to be seen.
