The infrared satellite IRAS. The main task of the IRAS telescope was the search of a longwave infrared radiation, composing the maps of the sky in the infrared range. IRAS telescope helped to discover new galaxies, to study the properties of the dust particles in our galaxy, which opens the character of a star hiding somewhere in the sky. ... For 6 months of observation it discovered 6 new asteroids, allowed to find out the nature of the dust zones between Mars and Jupiter orbits. ...

... 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. ...

THE ARGUMENT AGAINST LONG EXTRAGALACTIC DISTANCE SCALE Gaseous discs of S0 -- Sd galaxies appears to be gravitationally stable or close to stability. Dependence of the gravitational stability parameter of gaseous disc $M_g/M_c$ upon the color index $(B-V)^0_T$ which reflects a relative number of young stars, is found. Here $M_g$ is total mass of gas in a galaxy, $M_c$ - mass of gas which corresponds to marginal stability of gaseous disc at distances from center. ...

Distant globular clusters with anomalously small masses. ... We found that 10 metal-poor globular clusters are greately distinguished for anomalously small masses on the "destruction rate-mass" plain. ... Note that 10 distant clusters of anomalously small mass selected by us proved to be younger and with an average metallicity <[Fe/H]> = -1.36 ? ... It looks as if only far from the centre of the Galaxy, conditions are created that lead to formation of globular clusters with anomalously small masses. ...
