On November the 23rd, Institut d’Astrophysique Spatiale (IAS) will celebrate the 20 years since its installation in Orsay. Inaugurated in 1992 and originating from the merger of several teams of astrophysicists from LPSP (Verrières-le-Buisson), CSNSM (Orsay), and ENS (Paris), IAS has a mission of conceiving, developing and exploiting experiments of astrophysics, mainly installed onboard space missions.

By combining two of the most advanced telescopes in the world -- the new Atacama Large Millimeter Array (ALMA) and the Very Large Telescope (VLT) of ESO -- a team of astronomers led by IAS graduate student Cinthya Herrera has now for the first time traced the very first steps in the formation of young super-star clusters in a nearby galaxy merger, the 'Antennae'.

The Institut d'Astrophysique Spatiale is going to participate to the national open lab days “Fête de la Science”. It will open its doors to the public on Sunday, October the 14th from 2 to 6PM for a poster exhibition, talks, and visits to the Calibration Station.

By analyzing the Paris meteorite, a team of researchers from Institut d'Astrophysique Spatiale (IAS, CNRS/Université Paris-Sud) has shown evidence of organic materials similar to those of the interstellar medium.
