Aurora_Borealis_-_03.jpgAurora in the Northern Skies57 visiteUn frame davvero molto bello ma che, a parere del nostro Esperto di Fotografia, è stato "taroccato" nelle colorazioni. In realtà la nostra non è una "conclusione scientifica" quanto, piuttosto, il frutto di una sensazione basata sia sull'esperienza (le Aurorae "rosse" sono rare, quelle "fucsia e rosa"...di fatto inesistenti...), sia sull'incoerenza cromatica dei particolari della fotografia una volta che essa è stata scomposta nei suoi canali principali.
Comunque sia...una bella immagine!MareKromium

The_Sun.jpgPartial Eclipse57 visiteCaption NASA:"On Monday, March 19, 2007, shortly before the Equinox, locations in Asia and the Arctic were favoured by the New Moon's shadow during a partial Solar Eclipse. Although the view from Goa, India, found the eclipsed Sun near the horizon, photographer Joerg Schoppmeyer was still able to capture this lovely image, combining celestial with terrestrial silhouettes.
The next eclipse season will begin in late August this year, featuring a total Lunar Eclipse on August 28, and another partial solar eclipse on September 11. Compared to the March 19th eclipse, the September 11th eclipse will be seen on the other side of our fair planet, from parts of South America and Antarctica".

M-45~0.jpgM 45 and Venus57 visite"...L'Opium agrandit ce qui n'a pas de bornes,
Allonge l'Illimité,
Approfondit le Temps, creuse la Volupté,
Et de plaisirs noirs et mornes
Remplit l'ame au-delà de sa capacité..."

PIA09956.jpgCosmic "Merger"57 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

Big_Dipper-1.jpgThe "Big Dipper"...again!57 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

Puzzle-Cook.jpgOne piece after another...57 visite"...Ed alla fine non restano che ricordi.
Sorrisi, lacrime, sensazioni di caldo e di freddo.
L'ultimo - e più prezioso - patrimonio che non potrò mai lasciare in eredità: la mia Memoria..."

Aurora_Borealis-2.jpgAurora Borealis over Juneau57 visiteCaption NASA:"Some auroras can only be seen with a camera. They are called sub-visual and are too faint to be seen with the unaided eye. The reason is that the human eye only accumulates light for a fraction of a second at a time, while a camera shutter can be left open indefinitely. When photographing an already picturesque scene above Juneau, Alaska, USA, a camera caught green sub-visual aurora near the horizon. Auroras are sparked by energetic particles from the Sun impacting the magnetic environment around the Earth. Resultant energetic particles such as electrons and protons rain down near the Earth's poles and impact the air.
The impacted air molecules temporarily lose electrons, and when oxygen molecules among them reacquire these electrons, they emit green light. Auroras are known to have many shapes and colors". MareKromium
