Big_Dipper-1.jpgThe "Big Dipper"...again!59 visiteCaption NASA:"Why would the dome of a telescopic observatory appear translucent red? As one of the telescopes of the Etscorn Observatory of New Mexico Tech waited to inspect small portions of the night sky, playful observers decided to make this unusual image. Tricks needed to create this seemingly impossible shot included opening the observatory dome slightly, using a red light to illuminate the inside of the dome, spinning the dome, and using a long exposure. The open slit in the dome then allowed the camera to incrementally image the inside of the observatory, including the telescope. A fortuitous break in the clouds allowed the stars of the Big Dipper asterism to shine through". MareKromium

SOL050-2N130812340EFF1000P1901L0M1-2.jpgAnother "Silver Anomaly" (2) - Sol 50 (extra-detail mgnf)522 visiteLa forma dell'oggetto è affusolata e (apparentemente) liscia, del tutto priva di asperità e di angoli vivi; il colore è argenteo (metallico) e l'oggettiva "alienità" di questo dettaglio in rapporto al paesaggio circostante è ovvia.
L'oggetto, inoltre, potrebbe trovarsi in loco da (relativamente) poco tempo.

PIA09956.jpgCosmic "Merger"62 visiteThis artist's concept shows what the night sky might look like from a hypothetical planet around a star tossed out of an ongoing four-way collision between big galaxies (yellow blobs). NASA's SST spotted this "quadruple merger" of galaxies within a larger cluster of galaxies located nearly 5 BLY away.
Though the galaxies appear intact, gravitational disturbances have caused them to stretch and twist, flinging billions of stars into space -- nearly three times as many stars as are in our Milky Way galaxy. The tossed stars are visible in the large plume emanating from the central, largest galaxy. If any of these stars have planets, their night skies would be filled with the monstrous merger, along with other galaxies in the cluster (smaller, bluish blobs).
This cosmic smash-up is the largest known merger between galaxies of a similar size. While three of the galaxies are about the size of our Milky Way galaxy, the fourth (center of image) is three times as big.
All four of the galaxies, as well as most other galaxies in the huge cluster, are blob-shaped ellipticals instead of spirals like the Milky Way.
Ultimately, in about one hundred million years or so, the four galaxies will unite into one. About half of the stars kicked out during the merger will fall back and join the new galaxy, making it one of the biggest galaxies in the universe.MareKromium

North_Polar_Features-Dunes-MGS-06.jpgNorth Polar Dunes (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)61 visiteCaption NASA originale:"This MGS-MOC image shows dunes in the North Polar Region of Mars. In this scene, the dunes and the plain on which the dunes reside, are at least in part covered by a bright CO2 frost. Dark spots indicate areas where the frost has begun to change, either by subliming away to expose dark sand, changing to a coarser particle size, or both. The winds responsible for the formation of these dunes blew from the South-West toward the North-East.
