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.
A NASA instrument built to help astronomers learn about the structure and behaviour of neutron stars, super-dense stellar skeletons left behind by massive explosions, has been mounted to an observation post outside the International Space Station after delivery aboard a SpaceX supply ship earlier this month.
Astronomers are using the NASA/ESA Hubble Space Telescope to study aurorae — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the solar system, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, shortly to arrive at the gas giant.
