The US space agency NASA has tweeted a stunning time-lapse video of Earth shooted at a distance of nearly a million miles. The amazing video was made by combining more 3000 images that were captured in a year.
All the pics were taken using the Earth Polychromatic Imaging Camera (EPIC) aboard the Deep Space Climate Observatory (DSCOVR) satellite orbiting Earth at a distance of million miles. The satellite is located at a gravitationally stable spot in space between the Earth and the sun known as a Lagrange point.
EPIC camera took pictures of Earth in every two hours. First picture was captured on July 26, 2015, that showed spactacular view of our planet. EPIC camera went on to click thousands of images and the team has beautifully stitched all the images to make this incredible video.
‘On July 16, 2015 we released this spectacular image of Earth taken by Nasa’s EPIC camera,’ Jay Herman, the EPIC lead scientists for the DSCOVR mission, said the Nasa video.
‘Now we assembled more than 3,000 images captured by EPIC into a time-lapse sequence.’
‘The hourly images of the entire sunlit side of the Earth provided by EPIC will be used to study the daily variations of features over the entire globe, helping us to better understand and protect our home planet.’

EPIC help scientists in monitoring the climate of Earth, ozone layer, movements of clouds, aerosol levels and ultraviolet reflectivity of Earth. However, its primary goal is to keep a check on the solar wind — a constant stream of charged particles emanated from the Sun.
The DSCOVR camera can record ten wavelengths and scientists combine all the wavelengths to make an image that is visible by naked human eye.
In the video, we can see shadow of moon racing across Earth in the month of March.
Moreover, DSCOVR is a joint venture of NASA and National Oceanic and Atmospheric Administration (NOAA) launched on February 11, 2015. Since then it has been observing Earth and has a unique capability to process images faster than other Earth observatory satellite.
