... The TESIS is a set of solar imaging instruments developed by the Lebedev Physical Institute of the Russian Academy of Science, and launched aboard the Russian spacecraft CORONAS-PHOTON on January 30, 2009. The main goal of the TESIS is to provide complex observations of solar active phenomena from the transition region to the inner and outer solar corona with high spatial, spectral and temporal resolution in the EUV and Soft X-ray spectral bands. ...

The interstellar medium is the material that lies between the stars in a galaxy . This material can exist in several phases with a wide range in temperature (from tens of degrees to tens of millions of degrees Kelvin). In the coldest regions the material consists of molecular gas and dust; in the hottest regions the material is almost completely ionized. The Role of the Interstellar Magnetic Field A. Goodman .

Optical Filters . The polarizer quads were also designed to map onto a four-faceted WFC configuration and, consequently, also require a partial filter rotation of -33 degrees to move the filter quadrant 1 (nominal polarization angle 135 degrees ) into WFCs 2 and 3, with some vignetting of both camera fields. Several additional partial rotations have been added to allow observations with different polarization angles on the same CCD. ...

... NASA SPACECRAFT FINDS NEW EVIDENCE FOR WATER ICE ON MERCURY . ... The new data indicate the water ice in Mercury's polar regions, if spread over an area the size of Washington, D.C., would be more than 2 miles thick," said David Lawrence, a MESSENGER participating scientist at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., and lead author of one of three papers describing the findings. ... Water ice concentrations are derived from the hydrogen measurements. ...
