The instrument detects photons of light reflected from Earth’s surface and atmosphere in 22 different wavelengths, Nasa said. The images are captured using the Visible Infrared Imaging Radiometer Suite. “By studying Earth at night, researchers can investigate how cities expand, monitor light intensity to estimate energy use and economic activity, and aid in disaster response,” the organisation said on its website. A research team at Nasa headed by Earth scientist Miguel Roman of Goddard Space Flight Centre in the US is working to find out if night lights imagery could be produced and updated yearly, monthly or even everyday. The satellite images of Earth, which are often referred to as “night lights”, are produced every decade or so. The global maps provide a clear view of human settlements across the planet. The National Aeronautics and Space Administration on Wednesday released global maps of Earth at night, including stunning images of India.
