Watch Tim Peake’s spacewalk live

Britain’s first astronaut, Helen Sharman, received a congratulatory phone call from Tim Peake aboard the International Space Station during celebrations in London to mark the 25th anniversary of her historic mission to the Mir space station.

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.

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!!”
