High cadence observations of solar activity (active regions, flares, filaments) in the H$\alpha$ line were performed at Meudon and Haute Provence Observatories from 1956 to 2004. More than 7 million images were recorded, mainly on 35 mm films. After

For the future European Solar Telescope (EST) the Observatoire de Paris proposes a new generation of MSDP, an imaging spectro-polarimetry instrument. To validate this new generation, we develop a plane micro-mirrors beam slicer prototype that is test

The Polarimetric and Helioseismic Imager (PHI) on board of Solar Orbiter will observe the Sun to measure the photospheric vector magnetic field and the line-of-sight velocity. It will employ a narrowband filtergraph (FG) to scan the FeI 6173 A absorp

The sequence of seasonal events that occurs each Martian year around the two poles of Mars is more precisely described due to the input of new telescopic surveys and polarimetric measurements, combined with available orbital photographs, Viking lande
