The investigation of features of electromagnetic waves propagation, their generation and absorption in weakly inhomogeneous chiral media were started and the following results were obtained : . the governing equations to describe the electromagnetic waves interaction with inhomogeneous chiral plasmas were derived (together with N.S.Erokhin); . ... it was proven the 100 % hybrid mode conversion in the case of normal waves incidence upon inhomogeneous plasma (together with N.S.Erokhin); . ...
... COMPUTER SIMULATION OF RADIOWAVE MULTIPLE SCATTERING EFFECTS IN IONOSPHERE USING MONTE-CARLO METHOD . ... Distribution of reflected radiation on the ground is computed. ... Such influence can be remarkable if the scattering is multiple, i.e. the optical thickness for the scattering process is considerably greater than a unit. ... Radiation energy transfer in the slab is modeled by distribution of some particles carring small portions of radiation energy. ... The isotropic plasma approximation is...

... This gives us another handle on how distant the stars are. ... Stars differ not only in distance, but also in apparent brightness. ... Ranking stars by brightness . ... The brightness of the star decreases as the square of the distance. ... At what distance would a 100-watt light bulb have the same brightness as the brighter stars? ... So if the distance of the 100-watt light bulb was 5 kilometers, the distance of the brighter stars would be 10,000,000,000,000 kilometers, or about a light-year. ...

... Introduction: In the present work the morphometric parameters for 87 large martian craters [1](with diameters from 411 up to 110 kms) have been determined: depth of a crater, the relation of depth of a crater to diameter (/D), height of a rim h, with the help of profiles constructed on the basis of supervision of space vehicle MGS [2].The comparison with similar morphometric parameters of large lunar craters also is fulfiled. ... 2000) Morphological Calague Of the Craters Of Mars. ...
... Bad Astronomy . ... Bitesize Astronomy . ... The next step up are true clusters, called open clusters . Open clusters (sometimes misleadingly called "galactic clusters") are groups of stars ranging in size from a few dozen stars up to tens of thousands. ... The youngest is about 1 or 2 million years old, while the oldest is about 6 or 7 billion years, making it just older than our own solar system. ... So by looking at the stars in the cluster we can tell pretty well how old they are. ...
