Most satellites are designed to observe Earth during the day – a time when they can observe our planet fully illuminated by the sun. NASA says that its new sensor, a Visible Infrared Imaging Radiometer Suite or (VIIRS), is sensitive enough to detect the nocturnal glow produced by Earth’s atmosphere and the light from a single ship in the sea. Judging from the images in the gallery, you will observe that they were taken gradually over the course of the year. You’ll even see a night image of a gas drilling activity in North Dakota as well as the illuminating waters of the great Nile river. Click on the images in the gallery to enjoy these one-of-a-kind photos of our beloved planet Earth. Cheers!
