The UK under a curtain of aurora

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.

Three crewmen from Russia, the United States and Great Britain blasted off toward the International Space Station on Tuesday, rocketing into space from the Baikonur Cosmodrome in pursuit of the orbiting research lab.

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.
