... 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 hard (power-law spectrum) X-ray beam sweeps around and illuminates the accretion disk, which reradiates a soft X-ray (blackbody) component. ... X-ray binaries owe their prominence to one of the most efficient energy release mechanisms known: accretion onto a compact object. In the accretion process gas from the atmosphere of the less dense companion is accelerated toward the extremely dense compact star. ...
