Africa, amazing Africa, both lush and arid, mystical and lucid in history, landscape and population. And from space, this amazing continent is more than that, it is breathtaking, an awe-inspiring landmass full of imagination and power and thanks to the latest NASA photos, you can now experience this too.
According to the fascinating website, Space.com, NASA has a satellite which is constantly pointed at the sunlit side of Earth, allowing some crystal-clear viewing of Africa from space. The project is a joint venture between NASA, the National Oceanic and Atmospheric Administration, and the U.S. Air Force
The photo was taken from the Deep Space Climate Observatory (DSCOVR), from a distance of 1 million miles (1.6 million kilometers) at a ‘gravitationally balanced point between the Earth and sun.’ The photo is made up of three separate shots taken with DSCOVR’s EPIC (Earth Polychromatic Imaging Camera) camera on 6 July. Each shot was taken minutes apart and focused on different channels of the camera’s sensors – red, green and blue. In this way, the sunlit surface of the planet was photographed over a variety of different wavelengths, including visible light, infrared and ultraviolet wavelengths.
The photo shows the Sahara desert to the south and the Nile River flowing to the Mediterranean Sea, NASA officials said in an image description. NASA are using the images to measure the ozone and aerosol levels present in the atmosphere.
