... Research objects and scientific purposes . Space scientific program includes development and launch of two supersmall spacecrafts "Universitetskiy" and "Kompas-2" intended for monitoring of radiation conditions near the Earth. ... All the studies conducted in the near-Earth space are characterised by strong radiation fields. ... The circular polar orbits, which cover all the near-Earth space, are the most favorable for comprehensive studies of the radiation conditions near the Earth. ...

... 400mm f/2.8 Nikor lens: images the sky on the entrance slit. ... The optical system maintains image quality along the slit length so that each row of the image is a spectrum of that spatially selected region of the sky. 180mm f/2.8 Nikor lens: collimates the light from the slit. ... The auxiliary optical platform on WISPI now accomodates a short focal lens and a guiding/imaging video system that may use sub-pixel corrections to provide feedback to the tracking drive motors. ...

... A faint, dusty rose of the northern sky, emission nebula IC 410 lies about 12,000 light-years away in the constellation Auriga. The cloud of glowing hydrogen gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. ... These "tadpoles" (seen just below center) are regions of denser, cooler gas, and more slowly resist the erosive radiation from the hot stars. ...

... We present a photometric and spectroscopic study of the unique isolated nearby galaxy KKR25. The isolated dwarf spheroidal (dSph) galaxy KKR25 was discovered by Karachentseva, Karachentsev Richter (1999, A , 135, 221) during the search of dwarf galaxies in the direction of the Local Void. In spite of its isolation KKR 25 has no gas and looks like a normal dwarf spheroidal system. ... This is the first known planetary nebula in a dwarf spheroidal galaxy outside the Local Group. ...
