When scientists realised that observing and analysing oscillations in the Sun could provide information about its interior, it was only a matter of time before Helioseismology was put to work on other stars

When we look at the Sun we cannot penetrate beyond its outer surface, the photosphere, which emits the photons that make up the radiation we can see. So how can we find out what is inside it?

One hundred and fifty experts in Solar and Stellar Seismology from over twenty countries will converge on Lanzarote from the 1st to the 5th February for the 4th HELAS International Conference, organised by the Instituto de Astrofísica de Canarias (IAC)

ESA's Herschel Space Observatory was launched on 14 May 2009. After a short commissioning and performance verification period, the science demonstration observations started in September 2009. Herschel is now carrying out routine science observations. The three instruments (SPIRE, PACS and HIFI) are working extremely well. The IAC is part of the SPIRE and PACS instrument consortia and has contributed flying hardware and software. The first results of the many Herschel Key Projects were presented at the ESLAB 2010 symposium in ESTEC (May 2010) and have been published in July 2010 in a special

The CoRoT satellite discovers the first Jupiter-like exoplanet, which can be studied in detail when it passes in front of its central star. The CoRoT satellite, operated by the French space agency CNES, has discovered a Jupiter-sized planet orbiting a star similar to the Sun in the constellation Serpens Cauda at a distance of 1.500 light-years from the Earth. The parameters of this gas giant, which has features in common with the majority of exoplanets discovered so far, represents a valuable standard model when it comes to identifying new Jovian-type bodies with moderate temperatures

The quiet Sun (the 99%, or more, of the solar surface not covered by sunspots or active regions) is receiving increased attention in recent years; its role on the global magnetism and its complexity are being increasingly recognised. A picture of a rather stochastic quiet Sun magnetism is emerging . From these recent works, the quiet Sun magnetism is presented as a myriad of magnetic field vectors having an isotropical distribution with a cascade of scales down to the mean free path of the photon (1 marcsec, or 10km on the solar surface). But this chaotic representation also shows clear
