On Thursday 12th May the space agencies ESA and NASA celebrated at a workshop the XX anniversary of the SOHO (Solar and Heliospheric Observatory) satellite at the Institut D'Astrophysique Spatiale(IAS), at Orsay, Paris, a reunion at which members of the Instituto de Astrofísica de Canarias (IAC) were present. The IAC participated from the start in two of the twelve instuments on board the satellite: GOLF (Global Oscillations at Low Frequency) and VIRGO (Variability of IRradiance and Gravity Oscillations). The previous day during the afternoon the group of researchers on this latter instrument held another commemorative workshop.

SOHO was launched on December 2nd 1995 and was placed at the L1 Lagrangian point on an orbit predicted to last two years with a possible extensión to four. Its objective was an in depth study of the Sun using twelve sophisticated instruments which have now been working for 20 years, yielding very valuable information about our star. This satellite, which was even “lost” in space for several months during 1998, has produced over 5,000 articles which have revolutionized the field of Solar Physics. The celebration was a tribute to one of the most productive and long-lasting satellites which have been launched in the past decades.

    Claude Nicollier tells of his experience as an astronaut at the IAC
    On Wednesday 30 October, the headquarters of the Instituto de Astrofísica de Canarias (IAC) received a talk by the first Swiss astronaut, Claude Nicollier, who wanted to share his experience in space with the personnel of the IAC. Claude Nicollier is the first Swiss astronaut to have flown into space. After his studies at the Universities of Geneva and Lausanne, Claude joined ESA as a member of their first group of astronauts. Since 2007 Nicollier has been a Professor at the Federal Polytechnical School at Lausanne. He has spent more than 1000 hours in space (more than 42 days) including a

    The synchronized dance of a system of six planets is revealed
    An international collaboration, with participation by the Instituto de Astrofísica de Canarias (IAC), has found a system of six exoplanets orbiting a central star with a precise rhythm.This phenomenon, known as orbital resonance, is common during the starting phase of planet formation, but it is exceptional to find a system with such a large set of planets which conserves this kind of gravitational synchronism. This finding shows that the system has not undergone major changes during its six billion year history, so that it gives an unusual view of the formation and evolution of planets. The
