Photometric data gathered by INTEGRAL's Optical Monitoring Camera (OMC) has been used to study selected eclipsing binary stars for which the light curve had hitherto not been analyzed. This recent study by Petr Zasche (Astronomical Institute, Charles University in Prague) provides new key information on the basic properties of these binary systems - properties that were previously not known or only estimated with low precision. The INTEGRAL spacecraft is equipped with instruments dedicated...

During the very first observations of Rosetta's flyby target 2867-Steins in March 2006 the onboard camera OSIRIS obtained the most accurate "Ëœlight curve' of this asteroid so far. OSIRIS observed Steins from a distance of 159 million kilometres and, from there, it obtained images and important clues about its characteristics. Although ESA's Rosetta is still far away from its destination comet 67P/Churyumov-Gerasimenko and its flyby targets 2867-Steins and 21-Lutetia, scientists...
