Space photos from iss helps decode light pollution on earth
India TV NewsLondon: Photos taken by astronauts aboard the International Space Station have helped scientists reliably measure the amount of light pollution worldwide. “Until the advent of new satellites, astronaut photography was our only colour and high-resolution window on the Earth,” said lead scientist Alejandro Sanchez de Miguel from the Universidad Complutense de Madrid, Spain. The team that had researchers from Quebec-based Cegep de Sherbrooke college in Canada found that European countries and cities with a higher public debt also have higher energy consumption for street lighting per inhabitant. The total cost of the energy consumption for street lights is 6,300 million euros per year in the European Union, said the researchers in a project called “Cities at Night”.
