NASA astronaut Scott Kelly and ESA astronaut Tim Peake shared a series of aurora photographs taken from the International Space Station on 20 January 2016. The dancing lights of the aurora provide spectacular views on the ground, but also capture the imagination of scientists who study incoming energy and particles from the Sun.

Tim commented on this image: “Today’s exhilarating spacewalk will be etched in my memory forever — quite an incredible feeling!”
Scientists are using photographs taken by astronauts aboard the International Space Station (ISS) to reliably measure the amount of light pollution worldwide and to produce a global colour map of the Earth at night. The total cost of the energy consumption for streetlights is estimated by the study to be 6300 million euros/year in the European Union.
