Ten new planets discovered

An international team, including scientists from the University of Oxford, has discovered 10 new planets. Amongst them is one orbiting a star perhaps only a few tens of million years old, twin Neptune-sized planets, and a rare Saturn-like world, a release by the University of Oxford said on Wednesday
.
The planets were detected using the CoRoT (Convection, Rotation and Transits) space telescope, operated by the French space agency CNES.
It discovers planets outside our solar system — exoplanets — when they ‘transit’, that is pass in front of their stars. Out of the 10 new exoplanets (CoRoT-16b through to 24b and c) seven are hot Jupiters ,some of which are unusually dense and/or on unusually elongated orbits.
It also includes a planet slightly smaller than Saturn, and two Neptune-sized planets orbiting the same star.
Dr Suzanne Aigrain of Oxford University’s Department of Physics, lead UK scientist for CoRoT, said: “CoRoT-18b is special because its star might be quite young. Finding planets around young stars is interesting because planets evolve very fast initially, before settling into a much steadier pattern of evolution.”
