... Sternberg Astronomical Institute , Moscow University . ... Present edition unites two parts of Catalogue of interacting galaxies by B.A.Vorontsov-Velyaminov: the first part (Part 1) containing 355 systems was published in 1959 [1] and the second one (Part 2) with 497 objects - in 1976 [2].Thus two published parts of Catalogue include 852 interacting systems. ... All new of them (1162 by number) were taken from the comments to the galaxies in Morphological catalogue by Vorontsov-Velyaminov et al.[ ...

Introduction The suggested invention relates to attitude control system of a spacecraft. ... Systems without interaction with ambient (Systems with jet engines) Here, for instance, we can put systems, which can generate torque because of jettisoning any particles or gas. ... The main element of the suggested attitude control system is an electrical motor, which main feature is absents of a stator. ... 3 Block diagram of an attitude control system on a jet engines base. ... It is a system with| | ...

... The event, a Type II supernova explosion, would have briefly dominated the night sky on Earth. ... Popularly known as the Veil Nebula, NGC 6960, NGC 6992, and NGC 6995 together constitute the corpse of a single supergiant star that perished in that supernova explosion. ... Such stars age about 1,000 times faster than does our Sun. ... Each nuclear-fusion stage releases energy and helps the star fight the ever-present pull of gravity. ...

... The engine operates with all three propellants (lox, kerosene, hydrogen) in the booster mode (mode 1) and transitions to bipropellant operation (lox, hydrogen) for the latter portion of the trajectory (mode 2). ... In mode 1 operation the hydrogen enhances the combustion of the kerosene to provide to tripropellant specific impulse levels higher than obtainable with separate combustion of the fuels. ... mode 1) . ...

... part 2 | ... Part 1 . The new concept of formation and development of the Solar system. ... Thus, the initial pulse of the rotation of a protosolar cloud of the solar system was determined as a result of the diversion of a part of the moment of the rotational pulse of the Galaxy. ... Besides this new approach to the pre-solar system as a system of the destroyed vortex structure, we can understand now a number of other peculiarities of the Solar system's structure. ...
