A new map of the dark matter made by the Atacama Cosmology Telescope. ̽��ֱ��orange regions show where there is more mass; purple where there is less. ̽��ֱ��typical features are hundreds of millions of light years across. ̽��ֱ��grey/white shows where contaminating light from dust in our Milky Way galaxy, measured by the Planck satellite, obscures a deeper view.

New findings that map the universe’s cosmic growth support Einstein’s theory of gravity

Sir Isaac Newton’s Cambridge papers added to UNESCO’s Memory of the World Register

01 December 2017

̽��ֱ��Cambridge papers of Sir Isaac Newton, including early drafts and Newton’s annotated copies of Principia Mathematica – a work that changed the history of science – have been added to UNESCO’s International Memory of the World Register.

A force to be reckoned with

27 November 2017

Gravity is one of the universe's great mysteries. We decided to find out why.

Think you know what gravity is? Think again. New research is revealing how little we know about this most mysterious of forces.

First detection of gravitational waves and light produced by colliding neutron stars

16 October 2017

In a galaxy far away, two dead stars begin a final spiral into a massive collision. ̽��ֱ��resulting explosion unleashes a huge burst of energy, sending ripples across the very fabric of space. In the nuclear cauldron of the collision, atoms are ripped apart to form entirely new elements and scattered outward across the Universe.

Planets similar to Jupiter are likely able to form on orbits shorter than the Earth’s

15 July 2016

After analyzing four years of Kepler space telescope observations, astronomers from the ̽��ֱ�� of Toronto, and of the ̽��ֱ�� of Cambridge have given us our clearest understanding yet of a class of exoplanets called “warm Jupiters”, showing that many have unexpected planetary companions.

Gravitational vortex provides new way to study matter close to a black hole

12 July 2016

An international team of astronomers has proved the existence of a ‘gravitational vortex’ around a black hole, solving a mystery that has eluded astronomers for more than 30 years. ̽��ֱ��discovery will allow astronomers to map the behaviour of matter very close to black holes. It could also open the door to future investigation of Albert Einstein’s general relativity.

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.’

Opinion: Inside Big Ben: why the world’s most famous clock will soon lose its bong

04 May 2016

Hugh Hunt (Department of Engineering) discusses the mechanism that makes Big Ben chime, and why it needs repairing.

Understanding gravity - from Newton to Hawking

29 April 2016

̽��ֱ��most important publication in the history of science – Isaac Newton’s own annotated copy of Principia Mathematica – and other seminal works by Copernicus, Einstein and Stephen Hawking, feature in a new film, released today, celebrating 600 years of Cambridge ̽��ֱ�� Library.

Opinion: ̽��ֱ��remarkable accuracy of the Trinity College clock – and what makes it tick

06 April 2016

Hugh Hunt (Department of Engineering) discusses the history of the Trinity College clock and how it keeps time.
