Watch Tim Peake’s spacewalk live

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.

Tim Peake sees the city lights of his capital city burning bright from the International Space Station last night. He tweeted: “London midnight Saturday – I’d rather be up here…but only just!!”

Former astronaut Piers Sellers, a British-born climate scientist who flew on three space shuttle missions to help construct the International Space Station, has died of pancreatic cancer at the age of 61.
