Paranal Observatory nights. [3] The concept of noctcaelador tackles the aesthetic perception of the night sky. [4]Depending on local sky cloud cover, pollution, humidity, and light pollution levels, the stars visible to the unaided naked eye appear as hundreds, thousands or tens of thousands of white pinpoints of light in an otherwise near black sky together with some faint nebulae or clouds ...
A preliminary description of the three areas of this diagram was made in 2003 by Eric F. Bell et al. from the COMBO-17 survey [1] that clarified the bimodal distribution of red and blue galaxies as seen in the analysis of Sloan Digital Sky Survey data [2] and even in de Vaucouleurs's 1961 analyses of galaxy morphology.
The first star in the list, Godzilla [1] — an LBV in the distant Sunburst galaxy — is probably the brightest star ever observed, although it is believed to be undergoing a temporary episode of increased luminosity that has lasted at least seven years, in a similar manner to the Great Eruption of Eta Carinae that was witnessed in the 19th ...
A brightest cluster galaxy (BCG) is defined as the brightest galaxy in a cluster of galaxies. BCGs include the most massive galaxies in the universe . They are generally elliptical galaxies which lie close to the geometric and kinematical center of their host galaxy cluster , hence at the bottom of the cluster potential well .
Gliese 667 Cc (also known as GJ 667 Cc, HR 6426 Cc, or HD 156384 Cc) [2] is an exoplanet orbiting within the habitable zone of the red dwarf star Gliese 667 C, which is a member of the Gliese 667 triple star system, approximately 23.62 light-years (7.24 parsecs; 223.5 trillion kilometres) away in the constellation of Scorpius.
Magnified image of the AMOLED screen on the Nexus One smartphone using the RGBG system of the PenTile matrix family. AMOLED (active-matrix organic light-emitting diode; / ˈ æ m oʊ ˌ l ɛ d /) is a type of OLED display device technology.
This galaxy cluster is at the coordinates RA 00h 44m 05.20s | Dec −20° 33’ 59.70" which is located in the Cetus constellation. Gioiello is unique compared to other clusters in that it still has many stars forming within its galaxies. This gives astronomers a new perspective on the state of younger galaxy clusters and the way that they behave.
