A Japanese legend says that if you can’t sleep at night it’s because you’re awake in someone else’s dream.
London, United Kingdom from space
The image above shows London and the southern half of Great Britain as it appeared on the night of March 27, 2012. The image was acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP, which includes a “day-night band”.
The day-night band observes light in a range of wavelengths from green to near-infrared, and uses light intensification to enable the detection of dim signals.
