PIONIER (VLTI)

The Precision Integrated-Optics Near-infrared Imaging ExpeRiment (PIONIER) is a visiting instrument at the ESO's Paranal Observatory, part of the VLTI astronomical observatory. It combines the light from four telescopes simultaneously and provide 0.001 arc seconds of angular resolution, the equivalent angular resolution of a 100 m telescope. PIONIER has been built at and has been installed at VLTI in November 2010. After few nights of commissioning, it is now routinely delivering science data.
