NASA recently released a stunning time-lapse video showing Earth in 365 different instances over the course of one year. The video was compiled from thousands of images taken by the EPIC instrument during our planet annual journey around the sun.
The time-lapse debuts with a picture taken on July 6, 2015 depicting the sunlit side of our planet. The video also shows the movement of clouds, seas, and changes in the weather, forests and deserts from all around the world in stunning detail.
EPIC measures the quality of air on Earth by assessing aerosol and ozone levels along with vegetation status and cloud cover.
Nasa’s Earth Polychromatic Imaging Camera , in short EPIC, is a scientific tool on board of the Deep Space Climate Observatory (DSCOVR), which is a NOAA space weather satellite. DSCOVR currently lies more than 90 million miles from the sun and 1 million miles from Earth.
From that point, DSCOVR looks for telltale signs of geomagnetic storms that can cut off communications on our planet. DSCOVR was put on orbit in Feb., 2015 by a Space X Falcon 9 rocket.
DSCOVR has managed so far to take more than 3,000 pictures of our planet in its 365-day-long trip around its host star. NASA researchers used these images to create the breathtaking time-lapse.

DSCOVR is the U.S.’s first operational space observatory in deep space. Researchers explained that it is in a stable position in a gravitational balance point called Lagrange 1. The observatory can warn scientists in advance about an incoming solar storm and help them make predictions on geomagnetic storms.
NASA scientists said that the time-lapse is comprised of more than 3,000 images of the sunlit side of our planet taken every two hours by the EPIC tool. These images are currently analyzed by NOAA scientists on a daily basis. The imagery helps them better understand our planet and find ways of protecting it.
The tool takes a shot of the planet every two hours, so you can clearly see the movement of the clouds and other factors in the weather system. The instrument can also capture photos of forests, oceans, and the polar regions.
EPIC scientists said that the colors in the images are the best estimate of what the human eye would see from the satellite’s position.
