Watch Tim Peake’s spacewalk live

An instrument aboard the International Space Station has detected a binary star system made up of a fast-spinning pulsar and a compact white dwarf that orbit each other every 38 minutes, a record for an accreting millisecond X-ray pulsar.

If you have never seen the International Space Station (ISS), make the most of clear skies over the next few nights. It’s capable of exceeding Venus at its brightest and visible for up to 7 minutes as it crawls across the sky in an arc from west to east. Find out when and where to see some favourable passes of this 420-tonne, 109-metre-wide spacecraft over the British Isles and Western Europe.

British astronaut Tim Peake, along with Soyuz commander Yuri Malenchenko and outgoing space station skipper Tim Kopra, departed the International Space Station today aboard the Soyuz TMA-19M capsule and landed safely in Kazakhstan at 1016 BST (0916 GMT).
