StairWaytoHaeven.jpgStairway to Haeven...65 visite"...Ciò che mi muove, in questa Vita, è la curiosità.
La curiosità di "vedere che cosa c'è oltre".
Oltre questa Terra, questo Mare, questo Cielo...Oltre questo Oggi ed oltre il Domani che verrà.
Oltre le nostre idee, le nostre paure, le nostre ipotesi e le nostre convinzioni.
Ti faccio un esempio: se, un giorno, mi capitasse di imbattermi in una scala che, poggiata sulla terra nuda, si alza verso l'Infinito, non credo che mi porrei troppe domande sulla sua Origine ed i suoi Scopi.
Penso che la guarderei, per qualche istante, e poi inizierei a salire, così, un gradino dopo l'altro, senza guardare giù...
Così: tanto per vedere sino a che punto sarei capace di arrivare, prima di sentire un brivido scorrere lungo la schiena ed il collo, e quindi rendermi conto che il mio Tempo, al pari del mio Cammino, è finito..."

PIA09956.jpgCosmic "Merger"71 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

The_Sun.jpgPartial Eclipse82 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".

FL-Anticrepuscolar Rays.jpgInfinite79 visiteCaption NASA originale:"(...) Pictured above are anticrepuscular rays.
To understand them, start by picturing common crepuscular rays that are seen any time that Sunlight pours though scattered clouds. Now although Sunlight indeed travels along straight lines, the projections of these lines onto the spherical sky are great circles. Therefore, the crepuscular rays from a setting (or rising) Sun will appear to re-converge on the other side of the sky.
At the anti-solar point 180° around from the Sun, they are referred to as anticrepuscular rays (...)".

Sun Pillars.jpgLight Pillars' Parade84 visiteDa "NASA - Picture of the Day" del 5 Marzo 2006:"How can an aurora appear so near the ground? Pictured above are not aurora but nearby light pillars, a local phenomenon that can appear as a distant one. In most places on Earth, a lucky viewer can see a Sun-pillar, a column of light appearing to extend up from the Sun caused by flat fluttering ice-crystals reflecting sunlight from the upper atmosphere. Usually these ice ice crystals evaporate before reaching the ground. During freezing temperatures, however, flat fluttering ice crystals may form near the ground in a form of light snow, sometimes known as a crystal fog. These ice crystals may then reflect ground lights in columns not unlike a Sun-pillar. In the above picture, the colorful lights causing the light pillars surround a ice-skating ring in Fairbanks, Alaska".
