... The source exhibits a mas-scale structure which, according to the USNO multi-epoch monitoring at 2.3 and 8.4 GHz over the period from 1994 July through 1998 April, undergoes considerable changes in the brightness distribution and positions of the major structural features. Our image is qualitatively consistent with the structural pattern of the source. ... We note a difference of ~90 in position angles of secondary components in our image and the 5 GHz VLBI image by Shen et al. 1998). ...

... Even though the DoD would ultimately select senior Air Force officials, US Navy oceanographers and Air Weather Service officers as shuttle payload specialists, MSEs would be the first personnel from an American military programme to go into space. ... One Air Force officer, Maj. ... Jacobson was concerned about shuttle launch delays and wanted the MSEs to understand that his mission, i.e., the launch of national security payloads, dwarfed their mission, flights in space by Air Force personnel. ...

... Сосед для Солнца - темная звезда . ... Он, по мнению астрономов, чрезвычайно напоминает пояс Койпера в Солнечной системе. Большинство (хотя и не все) объектов пояса Койпера располагаются в узком диапазоне орбит на удалении от 30 а.е. (орбита Нептуна) до 50 а.е. от Солнца. ... Объекты пояса Койпера (Седна, Квавар, Ксена) . ... Астрономы пришли к выводу, что параметры орбиты недавно обнаруженного планетоида Седна свидетельствуют о том, что наше Солнце может быть частью двойной звездной системы. ...

... GCR and SCR are primary cosmic rays. 10-15 years after the discovery of cosmic radiation (1919) there emerged two main avenues of investigation in the physics of cosmic rays (CR): 1) nuclear - elucidation of the origin of elementary particles and nuclear interactions; and 2) astrophysical (space physics) - solution of the problem related to the origin and variations (changes in intensity) of CR. ... Besides, the CR flux in interplanetary space is, strictly speaking, not isotropic. ...
