NEW NASA CAMERA PROVIDES AN ‘EPIC’ VIEW OF EARTH

This is what Earth looks like from a million miles away.
The stunning image, which focuses on America, was taken by the Deep Space Climate Observatory (DSCOVR) and is the satellite’s first view of the entire sunlit side of our planet.
It was presented to the White House today, prompting a tweet from President Barack Obama describing it as: ‘A beautiful reminder that we need to protect the only planet we have.’
The blue marble was captured by the Earth Polychromatic Imaging Camera (Epic) and created by combining three separate images to show the Earth in incredible detail.
The camera takes a series of 10 images using different narrowband filters – from ultraviolet to near infrared.
‘This first DSCOVR image of our planet demonstrates the unique and important benefits of Earth observation from space,’ said Nasa Administrator Charlie Bolden.

DSCOVR orbits the sun at a location called the Lagrange point 1, or L1, It’s from that unique vantage point that the Epic instrument is acquiring science quality images of the entire sunlit face of Earth. Data from Epic will be used to measure ozone and aerosol levels in Earth’s atmosphere, cloud height, vegetation properties and the ultraviolet reflectivity of Earth
