Video preview of Tim Peake’s spacewalk

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.

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!!”

Next to the Moon and Venus, the International Space Station (ISS) can be the third brightest object in the nighttime sky. During the first ten days of August, the ISS is well placed for viewing before midnight for observers in the British Isles. We show you how, when and where to see it.
