Some images show it to have a blue sky, others a red sky, and in yet others the sky is butterscotch. ... When the images from Mars are returned to Earth, and then processed to make a color image, what you are seeing at best is an approximation to what your eye can see. ... When that infrared filter greyscale image is used to construct a color image, the blue tab turns pink. ...

... We present a new method of the ionospheric irregularity investigation based on using of temporal structure function of the phase of the vertical sounding signal. ... Theoretical relation between structure functions of the phase variations and the irregularities can be obtained in the framework of a simple model of frozen irregularity horizontal drift. ... structure function ?? ... The irregularity structure function can be easily calculated if the irregularity spatial spectrum is known. ... Figure 1...

The revision of the MASS/DIMM star catalogue N. Shatsky, V. Kornilov March 16, 2008 Abstract The compilation of the (updated) version of the MASS (MASS/DIMM) device target catalogue is described. ... Then the list was cleaned according to following criteria: I. Remove stars too faint for a MASS device. ... Here the color equation of the Sternb erg device was taken: M AS S mag = V mag + 0.45 (B - V ); stars with M AS S mag > 3.2 were removed. ... This was made based on the GCVS4.2 catalogue data. ...

... Panoramic spectroscopy of the sample of 80 nearby lenticular galaxies is presented. ... By comparing the subsample of the S0s with the chemically distinct nuclei to the total sample of nearby S0s (Fig. 1), we have assured that the chemically distinct nuclei are always younger than the surrounding bulges: the mean age difference between the chemically distinct nuclei and their surrounding bulges is 2.8 Gyr while the age difference between the nuclei and the bulges for the whole sample is only 1 Gyr. ...
