... ИСТОРИЯ ЗВЕЗДООБРАЗОВАНИЯ . ... БЛИЗКИХ ГАЛАКТИКАХ . ... Для близких галактик доступны для наблюдений звезды практически всех возрастов: от только что рождающихся, до самых древних звезд с возрастами как у шаровых скоплений из гало нашей Галактики. Таким образом для близких галактик (в настоящее время до расстояний 4 Мпк) можно моделировать историю образования в них звезд (star formation history - SFH), начиная с эпохи первой вспышки SF и до недавнего прошлого. ... 1.2 Изучение звездообразования . ...
. F IGURE . 3. Relations between the metallicity and other GC parameters. The open triangles are thick-disk clusters; open circles, old halo clusters; filled circles, young-halo clusters; filled triangles, corona clusters; and crosses, metal-poor clusters with unknown (B–R)/(B+V+R) . Only clusters with R<60 kpc are shown in (c). A sharp jump near [Fe/H]=-1.0 is seen in all plots. discussion in the text | previous figure | next figure .
Large sunspots were occasionally seen far in the past without any instruments, when the sun was dimmed by thick haze, but not much was remembered of those observations. ... Sunspot Cycle (1850 - 1975) . One who was greatly influenced by Schwabe's discovery was an English gentleman of independent means, Richard Christopher Carrington , who devoted himself to the study of sunspots. ... Carrington had seen a flare, of the rare variety that is visible in white light (only about 50 are known). ...

The term "astronaut" derives from the Greek words meaning "space sailor," and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond. Since the inception of NASA's human space flight program, we have also maintained the term "astronaut" as the title for those selected to join the NASA corps of astronauts who make "space sailing" their career profession. ...
... Далее при достижении определенной температуры в центре звезды загорается гелий, а водород продолжает гореть в слоевом источнике и т.д. Уравнения использованные в этой программе достаточно очевидны: во первых это уравнение генерации энергии в ядерном синтезе около центра звезды, во вторых перенос энергии к поверхности излучением и конвекцией, уравнение гидростатического равновесия (в котором газовое давление и давление излучением уравновешиваются гравитацией) и уравнение сохранения массы. ...

... Bad Astronomy . ... Bitesize Astronomy . ... Keep Bad Astronomy close to your heart, and help make me filthy rich. ... Sometimes whole galaxies can be hidden away from us, yet so close we could practically stub our toes on them. ... Now look around: you can clearly see people a few meters away, fuzzily see them 10 meters away, and only barely see them 50 meters away. ... We have detectors that can see colors of light our eyes cannot, like ultraviolet, infrared (also known as IR) and radio waves. ...
