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

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.

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.

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.

An international exoplanet ‘think tank’ is meeting this week in Cambridge to deliberate on the ten most important questions that humanity could answer in the next decade about planets outside our solar system.

Astronomers have found the first evidence of comets around a star similar to the sun, providing an opportunity to study what our solar system was like as a ‘baby’.

Three Earth-sized planets have been discovered orbiting a dim and cool star, and may be the best place to search for life beyond the Solar System.

̽»¨Ö±²¥most detailed map of a small, rocky ‘super Earth’ to date reveals a planet almost completely covered by lava, with a molten ‘hot’ side and solid ‘cool’ side.

In 1995, in Geneva, PhD student Didier Queloz discovered a planet orbiting another sun – something that astronomers had predicted, but never found. Today he continues his terra hunting for extreme worlds and Earth twins in Cambridge.
