Triple_Sunrise.jpgTriple Sunrise66 visiteDa "NASA - Picture of the Day" del giorno 4 Agosto 2009:"How can the same Sun rise three times? Last month on Friday, 2009 July 10, a spectacular triple sunrise was photographed at about 4:30 am over Gdansk Bay in Gdansk, Poland. Clearly, our Sun rises only once. Some optical effect is creating at least two mirages of the Sun -- but which effect? In the vast majority of similarly reported cases, mirages of the brightest object in the frame can be traced to reflections internal to the camera taking the images. Still, the above image is intriguing because a sincere photographer claims the effect was visible to the unaided eye, and because the photographer took several other frames that show variants of the same effect. Therefore, polite readers are invited to debate whether the above image captures a particularly spectacular example of common reflections inside a standard digital camera, shows one of the most spectacular examples of atmospheric lensing yet recorded, or was caused by something completely different. If the discussion converges, the consensus will be posted here at a later date".MareKromium

Tunguska_Crater_-_Russia.jpgTunguska (Russia)262 visiteCosa succede quando un meteorite fa breccia nell'atmosfera terrestre ma non colpisce il suolo ed esplode invece a mezz'aria? Questo e' esattamente quello che accadde nel 1908 vicino al fiume Podkamennaya Tunguska. Sebbene non sia visibile alcun cratere, l'esplosione ha appiattito circa 80 milioni di alberi su un'area di 2.150 km quadrati di foresta.MareKromium

Umbra Fugax-1.jpgUmbra Fugax90 visiteSiamo al termine della spettacolare eclissi totale del 29 Marzo 2006 e l'ombra della Luna sta già lasciando il posto al Sole. Se osservate il frame a schermo pieno e con una certa attenzione dovreste riuscire a notare che, in alcune zone del cielo - già quasi del tutto libere dalla "notte" - si intravedono ancora dei corpi luminosi puntiformi che, ad una prima e sommaria occhiata, potrebbero sembrare delle stelle molto luminose che stanno per svanire nella luce del giorno. Ma non è così: si tratta, a nostro parere, di un abbastanza consueto e caratteristico photoartifact.
In ogni caso, un frame davvero molto bello.
Caption originale:"During the March 29, 2006 total Solar Eclipse, the Moon's dark central shadow (or "umbra") is vanishing beyond the horizon in this dramatic view of the landscape a few km South-East of Incesu, Anatolia, Turkey. The large, snow covered mountain in the distance is 3.250 mt high volcano Hasan Dag. The foreground is growing brighter as eclipse watchers are just beginning to see rays of sunlight peek around the lunar limb, while the mountains on the horizon, left of Hasan Dag, are still completely shadowed by the Moon. For the watchers along this part of the shadow track, the total phase of the eclipse lasted less than 4', as the umbra raced over them at more than 3000 Km per hour".

Under_The_Stars.jpgOld Faithful...78 visite
Caption NASA:"You don't have to be at Yellowstone to see a sky this beautiful, but it helps. Only at Yellowstone National Park in Wyoming, USA, would you see the picturesque foreground of the famous "Old Faithful Geyser" erupting in front an already picturesque sky. Old Faithful Geyser, visible in the foreground, is seen propelling a stream of hot water over 30 mt up in the air. This happens predictably for a few minutes about every 90 minutes. Also predictable are the brightest orbs that popular the nighttime sky, although those visible at any one time keep changing. Visible far in the background sky of this mid-June image are the plane of our Milky Way Galaxy on the left, and the bright planet Jupiter on the right. Jupiter is the brightest celestial object in the entire image. Old Faithful has been erupting at least since the late 1800s".
Nota: siamo curiosi di vedere quando la NASA "ipotizzerà" (ironizziamo, poichè le evidenze fotografiche in nostro possesso sono già innumerevoli) che alcuni fenomeni attualmente catalogati come "minicicloni" o "Dust Devils" (DD) sono, in realtà (ed in maniera particolare nelle aree presso-polari), dei geysers.
Geysers che, a volte, eruttano fango e ghiaccio e, altre volte - forse - acqua calda ed idrocarburi.
Staremo a vedere...MareKromium
