... 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. ...
We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
ВОЯДЖЕР-2" ИССЛЕДУЕТ НЕПТУН . ... Лишь после успешного сближения "Вояджера-1" с Титаном на расстоянии 4 тыс. км, было решено направить "Вояджер-2" к Урану, а затем и к Нептуну, хотя вероятность сохранения работоспособности станции к тому времени (август 1989 год) оценивалась лишь в 40%. ... Первоначально планировалось, что АМС пройдет 24 августа 1989 года в 1280 км от вершин облаков Нептуна с пертурбационным маневром в поле тяготения планеты, обеспечивающим сближение с Тритоном до 800 км. ... Нептун . ...
... Multiexposition 34 images Sun 1/1000 sec f/22 and 1 image background. ... It shows position of the Sun on the sky in the same time of a day during one year. Analemma - a trace of the annual movement of the Sun on the sky - is well known among experts of sun-dials and old Earth's globes as a diagram of change of seasons and an equation of time. ... Previously, the position of the Sun on the sky was calculated with computer as well as optimal moments of time for taking each of the exposures. ...
