Dead satellite finds a calm centre at the heart of brightest galaxy cluster in the sky

06 July 2016

With its very first – and last – observation, the Hitomi x-ray observatory has discovered that the gas in the Perseus cluster of galaxies is much less turbulent than expected, despite being home to NGC 1275, a highly energetic active galaxy.

Using gravitational waves to catch runaway black holes

30 June 2016

Black holes are the most powerful gravitational force in the Universe. So what could cause them to be kicked out of their host galaxies? Cambridge researchers have developed a method for detecting elusive ‘black hole kicks.’

Artist’s impression depicting a compact object – either a black hole or a neutron star – feeding on gas from a companion star in a binary system.

Winds a quarter the speed of light spotted leaving mysterious binary systems

27 April 2016

Astronomers have observed two black holes in nearby galaxies devouring their companion stars at an extremely high rate, and spitting out matter at a quarter the speed of light.

Local school takes classroom into space

13 January 2016

A primary school in Sawston spent the day learning all about space and one lucky 11-year old girl had the chance to try on a real space suit.

Gaia satellite and amateur astronomers spot one in a billion star

17 July 2015

The Gaia satellite has discovered a unique binary system where one star is ‘eating’ the other, but neither star has any hydrogen, the most common element in the Universe. The system could be an important tool for understanding how binary stars might explode at the end of their lives.

Planck reveals first stars were born late

05 February 2015

New maps from the Planck satellite uncover the ‘polarised’ light from the early Universe across the entire sky, revealing that the first stars formed much later than previously thought.

Mapping the weather on WASP-43b

09 October 2014

Two new studies have been used to make the most detailed weather map for a planet outside the solar system, where typical daytime highs reach 1500 degrees Celsius and winds exceed the speed of sound.

Smallest exoplanet ever found to have water vapour

An artist’s impression of a Type Ia supernova – the explosion of a white dwarf locked in a binary system with a companion star.

Gaia discovers its first supernova

12 September 2014

While scanning the sky to measure the positions and movements of stars in our Galaxy, Gaia has discovered its first stellar explosion in another galaxy far, far away.

Gaia-ESO data show Milky Way may have formed ‘inside-out’, and provide new insight into Galactic evolution

20 January 2014

Research on first data release from Gaia-ESO project suggests the Milky Way formed by expanding out from the centre, and reveals new insights into the way our Galaxy was assembled.
