... 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. ...

One of the insteresting results of Chandra and XMM-Newton observatories is the discovery of sharp structures in the X-ray surface brightness of galaxy clusters. These structures (a.k.a. cold fronts) are likely associated with the contacted discontinuities formed when a hot gas flows over a colder gravitationally bound gas cloud. ...

. Созвездие Щит . Созвездие (лат. Scutum, сокр. лат. Sct) расположено на Млечном Пути между Орлом и хвостом Змеи. Оно введено Яном Гевелием в честь польского короля Яна Собеского III и первоначально называлось Щит Собеского. Кульминирует в полночь 1 июля. В созвездии Щита обратите внимание на два ярких рассеянных звездных скопления NGC 6705 (Wild Dusk Cluster) и M26.

Ранее астрономы считали, что этот огромный и относительно тусклый остаток сверхновой, которая вспыхнула примерно 5000-8000 лет назад, находится на расстоянии около 2500 световых лет от Земли, однако исследования, которые выполнили космический телескоп 'Хаббл', показали, что туманность находится гораздо ближе - на расстоянии всего 1470 световых лет. ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

. F IGURE . 10. Dependence of cluster metallicity on (a) Galactocentric distance and (b) distance from the Galactic plane. The filled and open circles correspond to the young and old halos, respectively, and the straight lines are the corresponding rms regressions. The small square shows the old-halo cluster excluded from computations based on a 3 criterion. discussion in the text | privious figure | next figure .
