... The ancient chronical said about the colour rings around the Sun and the Moon, about three suns in the sky, light columns, bright lightning, different "comets" rushing to the Earth, moving among the stars or round the Earth with the sky. All these occurrences may be divided into three categories: one that occur in the near or far space, processes going on in the Earth atmosphere under the influence of cosmic factors and at last the occurrences connected with the Earth atmosphere. ...

Search for the youngest galaxies and the problems of galaxy formation . During 2 last years of work on the search for new galaxies in the phase of first star formation (SF) burst there were carried out spectral observations of 39 blue compact galaxies (BCGs) - candidates to the most metal deficient unevolved galaxies. 23 of them indeed have appeared new metal-poor galaxies with the oxygen abundance (O/H) (as an indicator of chemical evolution) less than 1/10 of the solar value. ...
