... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

The Discovery of the Galilean Satellites . ... Probably the most significent contribution that Galileo Galilei made to science was the discovery of the four satellites around Jupiter that are now named in his honor. Galileo first observed the moons of Jupiter on January 7, 1610 through a homemade telescope. He originally thought he saw three stars near Jupiter, strung out in a line through the planet. ...

... A light curve decomposition tool ( LFIT ) developed by Keith Horne and Tom Marsh and its application on HST-data of the eclipsing dwarf nova IP Peg will be presented. ... Our LFIT code decomposes time-resolved spectral data into N components with parameterized light curve shapes, solving for the spectra of each component. ... To apply this algorithm to the HST and UBVRI eclipses of IP Peg, we add an ellipsoidal light curve for the companion star, and a more detailed description of the bright spot. ...
