Material falling into a black hole casts X-rays out into space – and now astronomers have used the echoes of this radiation to map the dynamic behaviour and surroundings of a black hole itself.

An international team of astronomers has discovered an ancient and dramatic head-on collision between the Milky Way and a smaller object, dubbed ‘the Sausage galaxy’. The cosmic crash was a defining event in the early history of the Milky Way and reshaped the structure of our galaxy, fashioning both the galaxy’s inner bulge and its outer halo, the astronomers report in a series of new papers.

In a series of experiments conducted last month, Cambridge researchers experienced weightlessness testing graphene’s application in space.

The first results from the Gaia satellite, which is completing an unprecedented census of more than one billion stars in the Milky Way, are being released today to astronomers and the public.
