NASA astronaut Terry Virts captured this stunning image of the United Kingdom, Ireland and Scandinavia on a moonlit night beneath an glowing curtain of aurora. Virts, a flight engineer on the International Space Station with Expedition 42, took the image on 6 February 2015.
Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, six or more years of data from NASA’s Fermi Gamma-ray Space Telescope has broadened the mission’s dark matter hunt using some novel approaches.
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.
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.
