Umbriel . Uranus II . Umbriel [UM-bree-ul] is the darkest satellite of Uranus. It is about the same size as Ariel and has about the same density. The surface appears to be old with large craters and does not change much from one location to another. Near the top is a puzzling bright ring called the fluorescent cheerio . ... Dark regions are represented as red and bright regions are represented as blue. The two white regions are bright ejecta from two fresh craters. ...

Астрономия и Космос Небесные тела Планеты и их спутники . Видимым парадом планет называется планетная конфигурация, когда пять ярких планет Солнечной системы (Меркурий, Венера, Марс, Юпитер и Сатурн) в своем движении по небосводу подходят друг к другу на близкое расстояние и становятся видны в одно время в небольшом секторе (10 - 40 градусов) неба. ... Из выше описанного видно, что парад планет можно наблюдать, либо вечером, либо утром. ... Не пропустите ОСЕННИЙ ПАРАД планет 2002 года! ...

For many years, CCDs had much higher quantum efficiency in the Red than in the blue because the devices were physically thick (200-300 microns of material). In the blue, the absorption depth for photons in silicon is only about 2000 angstroms (1/2 their wavelength) and typically the electrodes are insulated by poly-silicate gates which are around 5000 angstroms thick. ... In what follows, we offer several examples and images taken with wide field CCD systems. Page 3 . ...

... Einstein data for SNR are available as images on magnetic tape or diskette and as tables of counting rates. ... In seven cases, with coverage from 35% to 90%, we have calculated an HRI rate for the entire SNR by using the observed IPC data and assuming the ratio of HRI to IPC rates was the same for the observed and the unobserved parts of the remnant. ... Positions of the bright bulge sources and remnants in the galactic plane are known and the rates in table 2 are free of the effects of these. ...

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). ...
