New Time-Lapse Video Taken From Outer Space Captures A Year On Earth
In a satellite a million miles away, NASA's EPIC camera was able to capture a year's worth of images in a time-lapse video that showed the earth's rotation around the sun. the images of earth were compliled through 3,000 images to form the timelapse video , released just earlier this week.
To mark one-year of our EPIC camera capturing Earth from 1 million miles away, here's a 3,000 image time-lapse.https://t.co/UDapLLkdIi

According to The Telegraph UK, Epic took one photo of the earth every two hours, revealing how the planet could look from the eyes of humans. The time-lapse also showed how the moon's shadow passed over during the solar eclipse last March 2016.
Epic allows scientists to monitor ozone and aerosol levels in the Earth's atmosphere, including with it cloud height, vegetation properties, and even the UV reflectivity. NASA's DSCOVR team, which assembled the video, compiled 3,000 images from EPIC, which, over the course of the year, was located at a gravitationally stable spot between the earth and the sun, known as the Lagrange point.
Regarding the images, NASA's Goddard officials wrote, "EPIC takes a new picture every 2 hours ... capturing the ever-changing motion of clouds and weather systems and the fixed features of Earth such as deserts, forests and the distinct blues of different seas."
Jay Hernan, EPIC lead scientist for the DISCOVR mission said that the first photo was released on July 16, 2015, and that to get the images, EPIC had to record images in ten different wavelengths to create an image that is similar to what the human eye can see.
The video also showed down to show the moon's shadow racing across the earth during the total lunar eclipse last March 2016. Space.com noted that the spacecraft recording the sun rising and setting about 13 times a day from the satellite's perspective.
