    NASA released images from a Coronal Mass Ejection (CME) captured by the instrument SECCHI on board the two twin probes which form the STEREO mission (Solar Terrestrial Relations Observatory) of NASA. The mission, launched in October 2006, is dedicated to the study of Earth-Sun relations. The instruments were designed and developed by American and European scientists. Various French scientific teams from laboratories of CNRS, supported by CNES, contributed to the development of three of the instruments on the probes.

    A new type of dusts just got discovered in the interstellar medium: nanoparticles which had been accelerated up to several hundreds of kilometers per second by the solar wind-carried magnetic field. This discovery was an unexpected spin-off of the S/WAVES experiment on board the Sun orbiting STEREO probes. This experiment used a radio receptor built by the Laboratory of Space Studies and Instrumentation in Astrophysics (Observatory of Paris/LESIA).
