Jean-Luc Beuzit |
| SPHERE (Spectro-Polarimetric High-contrast Exoplanet Research in Europe) is a second-generation instrument for the ESO Very Large Telescope (VLT) dedicated to the direct detection and spectral characterization of giant extra-solar planets, which is one of the most exciting but also one of the most challenging areas in modern astronomy due to the very large contrast between the host star and the planet at very small angular separations. SPHERE combines an extreme adaptive optics system, various coronagraphic devices and a suite of focal instruments providing imaging, integral field spectroscopy and polarimetry capabilities in the visible and near-infrared spectral ranges. After almost 10 years of development, SPHERE has been successfully commissioned at the VLT in 2014 and is now offered to the community since April 2015. I will give an overview of the science objectives and main instrument features, review the achieved performances and present a summary of the main results obtained during the first year of operations. |
