This Jan. 30, 2012 image of Earth was created from photographs taken by the Visible/Infrared Imager Radiometer Suite (VIIRS) instrument aboard the Suomi NPP satellite. Many features of North America and the Western Hemisphere are particularly visible. The composite was created from the data collected during four orbits of the robotic satellite taken earlier in January 2012 and digitally projected onto the globe.
VIIRS collects visible and infrared imagery along with global observations of Earth's land, atmosphere, cryosphere, and ocean, extending observational records collected by similar instruments aboard previously launched satellites, such as NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and NOAA's Advanced Very High Resolution Radiometer (AVHRR).
