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.
French astrophotographer Thierry Legault travelled to the suburbs of Philadelphia, USA to capture both the International Space Station and planet Mercury transiting the Sun on 9 May. This image includes multiple stacked frames to show the Station’s path in the fraction of a second it took to cross the Sun, while Mercury appears as a black dot at bottom-centre.
Urban dwellers may resign themselves to spotting the Moon, planets and the brightest stars with the unaided eye on a clear night, but every so often a bright satellite will catch your attention as it glides silently across the sky. The brightest is the 400-tonne International Space Station (ISS) whose orbit carries it directly overhead as seen from the British Isles and parts of Western Europe tonight.
