An international team of astronomers has detected titanium oxide in the atmosphere of an exoplanet for the first time. ̽»¨Ö±²¥, reported in the journal Nature, provide unique information about the chemical composition and the temperature and pressure structure of the atmosphere of this unusual and very hot world.

A star about the size of Saturn – the smallest ever measured – has been identified by astronomers. 

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. 

Some of the biggest names in science took part in a special public event yesterday (2 July) to celebrate the life and work of Stephen Hawking, on the occasion of his 75th birthday. 

An international team of astronomers, including researchers from the ̽»¨Ö±²¥ of Cambridge, used data gathered by the Kepler Space Telescope to observe and confirm details of the outermost of seven exoplanets orbiting the star TRAPPIST-1.

Researchers have shown how singularities – which are normally only found at the centre of black holes and hidden from view – could exist in highly curved three-dimensional space.

An international team of astronomers, including researchers from the ̽»¨Ö±²¥ of Cambridge, has made the most detailed image of the ring of dusty debris surrounding a young star and found that the ice content of colliding comets within it is similar to comets in our own solar system.

Martin Rees is Emeritus Professor of Cosmology and Astrophysics at the ̽»¨Ö±²¥ of Cambridge, the Astronomer Royal, a member of Britain’s House of Lords, and a former President of the Royal Society. ̽»¨Ö±²¥following interview was conducted at Trinity College, Cambridge, by ̽»¨Ö±²¥Conversation’s Matt Warren.

An international team of astronomers has found a system of seven potentially habitable planets orbiting a star 39 light years away three of which could have water on their surfaces raising the possibility they could host life. Using ground and space telescopes, the team identified the planets as they passed in front of the ultracool dwarf star known as TRAPPIST-1. ̽»¨Ö±²¥star is around eight per cent of the mass of the Sun and is no bigger than Jupiter.

̽»¨Ö±²¥Magellanic Clouds, the two largest satellite galaxies of the Milky Way, appear to be connected by a bridge stretching across 43,000 light years, according to an international team of astronomers led by researchers from the ̽»¨Ö±²¥ of Cambridge. ̽»¨Ö±²¥discovery is reported in the journal Monthly Notices of the Royal Astronomical Society (MNRAS) and is based on the Galactic stellar census being conducted by the European Space Observatory, Gaia.
