The European Space Agency's programme committee has just selected the ARIEL mission as the 4th intermediate class mission (budget 450 million euros) of the "Cosmic Vision" programme. ARIEL will be launched from the Kourou base in Guyana in May 2028 and will be placed in orbit at Lagrange L2, located 1.5 million kilometres from Earth. ARIEL is a space telescope that will systematically probe the atmospheres of a thousand extrasolar planets, from gas giants to rocky planets, whether hot or temperate around stars of different types. ARIEL will measure the composition and structure of planetary atmospheres, constrain the nature of planetary cores, detect the presence of clouds and study interactions with the host star.

With its observations in the middle-infrared range, the James Webb Space Telescope (JWST) is going to revolutionise our understanding of the Universe. After a competitive selection, its first observing targets have been unveiled. Over the hundred or so programmes proposed by researchers form all over the world, only 13 have been selected. One of them will be led by a collaboration involving IAS researchers.

An international scientific team including two co-Investigators from the IAS has determined the elemental composition of the dust of 67P/Churyumov-Gerasimenko, the comet explored by the European space probe Rosetta. Their results reveal some of the most carbon-rich materials and the least altered ever explored. This cometary carbon is essentially in a macromolecular organic structure, meaning that it is mainly in that form that it was delivered by comets to the primitive Earth.
