Эллиптическая галактика NGC 4636 . Астрономы, используя рентгеновскую обсерваторию Chandra, исследовали распределение скрытой массы у эллиптической галактики NGC 4636. Галактика удалена от нас на расстояние около 50 млн. световых лет и расположена в созвездии Дева . ... Так в NGC 4636 от 50% до 80% массы присутствует в виде темной материи, в радиусе около 35000 световых лет - это больше, чем расстояние от ядра Нашей галактики и до Земли. ...

November 1-4, 1993 . ... On Nov 2 (b), strong evolution of the chain takes place during the LDE/CME event occurred in AR 7613 (see Figure 2 for details): new chain fragments are developed from the regions 1 and 2 eastward and westward respectively. (d)-(e) - Comparing the Nobeyama radio heliograms with the Yohkoh/SXT images, one can see that during three days the long-living chain between sources 1 and 2 coincides with a sharp SE boundary of the large coronal hole. ...
... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...
... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...
