Cosmic dawn, when stars formed for the first time, occurred 250 million to 350 million years after the beginning of the universe, according to a new study led by researchers from the ̽��ֱ�� of Cambridge and ̽��ֱ�� College London (UCL). 

An international team of astronomers, led by the ̽��ֱ�� of Cambridge, announced the most detailed ever catalogue of the stars in a huge swathe of our Milky Way galaxy.

One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework. String theory is arguably the best-known proposal for a 'theory of everything' that would tie together our understanding of the physical universe.

“Weather” in clusters of galaxies may explain a longstanding puzzle, according to a team of researchers at the ̽��ֱ�� of Cambridge. 

̽��ֱ��Gaia satellite has spotted an enormous ‘ghost’ galaxy lurking on the outskirts of the Milky Way. 

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’. ̽��ֱ��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.

̽��ֱ��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. 

Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have formed in the Universe. These ‘newborns’ – observed as they appeared nearly 13 billion years ago – spun like a whirlpool, similar to our own Milky Way. This is the first time that it has been possible to detect movement in galaxies at such an early point in the Universe’s history. 

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.

A group of astronomers have shown that the fastest-moving stars in our galaxy – which are travelling so fast that they can escape the Milky Way – are in fact runaways from a much smaller galaxy in orbit around our own.
