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’. ̽»¨Ö±²¥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.

A plan to build a global network of STEM ambassadors to encourage women and girls into science, put forward by a Cambridge academic to the United Nations, will be discussed at the UNSPACE+50 event this week.  

An international team of researchers have identified ‘fingerprints’ of multiple metals in one of the least dense exoplanets ever found. 

̽»¨Ö±²¥European Space Agency’s Gaia mission has produced the richest star catalogue to date, including high-precision measurements of nearly 1.7 billion stars and revealing previously unseen details of our home Galaxy.

It is theoretically possible that habitable planets exist around pulsars - spinning neutron stars that emit short, quick pulses of radiation. According to new research, such planets must have an enormous atmosphere that converts the deadly x-rays and high energy particles of the pulsar into heat. ̽»¨Ö±²¥results, from astronomers at the ̽»¨Ö±²¥ of Cambridge and Leiden ̽»¨Ö±²¥, are reported in the journal Astronomy & Astrophysics.

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.

In a galaxy far away, two dead stars begin a final spiral into a massive collision. ̽»¨Ö±²¥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.
