SunDogs.jpgSuomi's Sundogs66 visiteWhat's happened to the Sun? Sometimes it looks like the Sun is being viewed through a large lens. In the above case, however, there are actually millions of lenses: ice crystals. As water freezes in the upper atmosphere, small, flat, six-sided, ice crystals might be formed. As these crystals flutter to the ground, much time is spent with their faces flat, parallel to the ground. An observer may pass through the same plane as many of the falling ice crystals near sunrise or sunset. During this alignment, each crystal can act like a miniature lens, refracting sunlight into our view and creating phenomena like parhelia, the technical term for sundogs. The above image was taken during early 2006 February near Helsinki, Finland with a quickly deployed cellular camera phone. Visible in the image center is the Sun, while two bright sundogs glow prominently from both the left and the right. Also visible is the 22° halo also created by sunlight reflecting off of atmospheric ice crystals.

Sun_Pillar.jpgA light "Sun-pillar" from somewhere in USA90 visiteCaption originale NASA. "Have you ever seen a sun pillar? When the air is cold and the Sun is rising or setting, falling ice crystals can reflect sunlight and create an unusual "column of light". Ice sometimes forms flat, stop-sign shaped crystals as it falls from high-level clouds; air resistance causes these crystals to lie nearly flat much of the time as they flutter to the ground. Then sunlight reflects off crystals that are properly aligned, creating the so-called "Sun-pillar" effect".

Sun_Pillar_in_blue_and_violet.jpgSun Pillar from Lake Tahoe - Nevada State Park (USA)115 visiteCaption originale NASA: "Sometimes the unknown is beautiful. In 2000 February near Lake Tahoe, Nevada, two amateur photographers noticed an unusual red column of light rise mysteriously from a setting sun. During the next few minutes, they were able to capture the pillar and a photogenic sunset on film. Pictured above, the red column is seen above a serene Lake Tahoe and snow-capped mountains across from Lake Tahoe-Nevada State Park. The mysterious column, they learned later, is a Sun Pillar, a phenomenon where sunlight reflects off of distant falling ice crystals".

Sun___clouds.jpgThe eclipse is real, but this picture is just a fake!59 visiteDa "NASA - Picture of the Day" del giorno 11 Aprile 2005:" (...) The above image composite was taken with a handheld digital camera. After a day of rain in Mt. Holly, North Carolina, USA, a partially eclipsed Sun momentarily peaked through a cloudy sky. After taking a sequence of images, the best eclipse shot was digitally combined with a less good eclipse shot that featured a passing airplane".
Nota: è deprimente vedere come gli Amici della NASA dìano spazio e valore ad un semplice "falso" ("digital combination of different images" significa solo "FABBRICARE UN FALSO").
Stiamo esagerando? Pensate: le fotografie, sino a qualche anno fa, rappresentavano un "istante cristallizzato" del mondo reale. Ora - così come avviene in questo specifico frame - ciò che viene "cristallizzato" è un evento che, nel mondo reale, NON E' MAI accaduto!
L'uso di jargon tecnologico potrà impressionare gli sprovveduti, ma la verità è che il confine fra 'Realtà ' e 'Ricostruzione Simulata della Realtà ' si è fatto sottilissimo...

Sundogs.jpgThe "Sundogs", again135 visiteCaption NASA originale da "NASA - Picture of the Day" del 23 Agosto 1999 :"What if you woke up one morning and saw more than one Sun in the sky? Most probably, you would be seeing Sundogs, extra-images of the Sun created by falling ice-crystals in the Earth's atmosphere. As water freezes in the atmosphere, small, flat, six-sided, ice crystals might be formed. As these crystals flutter to the ground, much time is spent with their faces flat, parallel to the ground. An observer may pass through the same plane as many of the falling ice crystals near sunrise or sunset. During this alignment, each crystal can act like a miniature lens, refracting sunlight into our view and creating parhelia, the technical term for sundogs. Sundogs were photographed here in a cloudy sky above the Very Large Array of radio telescopes. A bright Sundog is visible on the far right, and a dim one on the far left. Ice-crystals can create other strange illusions of the Sun and Moon including halos and pillars".

Sundogs1.jpgThe "Dogs of the Sun"141 visiteI "Cani del Sole", un evento naturale decisamente curioso e, purtroppo, piuttosto raro dalle nostre parti (diciamo purtroppo poichè si tratta di un fenomeno alquanto suggestivo). Secondo i Navajo, l'apparizione dei due (apparenti) Soli Minori (i "cani", appunto) accanto al Sole Maggiore, costituiva di regola un presagio favorevole e, per i guerrieri/cacciatori, il verificarsi di questa "apparizione" costituiva l'annuncio di una stagione di caccia (o anche di una semplice "battuta", magari) particolarmente favorevole. I "Cani del Sole" e la relativa leggenda vennero anche - incidentalmente - ripresi nel film (ormai entrato nella Storia del Cinema) "The Deer Hunter", con R. de Niro.

Sunrise.jpgCrepuscular Rays Over Utah60 visiteDa "NASA - Picture of the Day", del 31 Agosto 2005:"What could cause such rays of dark? Dark sky rays were caught in spectacular fashion earlier this month above Utah, USA. The cause is something surprisingly familiar: shadows. Clouds near the horizon can block sunlight from reflecting off air, making columns outward from the Sun appear unusually dark. Cloud shadows can be thought of the complement of the more commonly highlighted crepuscular rays, also visible above, where sunlight pours though cloud holes. Sometimes, on the opposite side of the sky, anticrepuscular rays can also be seen".

SunriseovertheParthenon.jpgDawn over the Land of Gods55 visiteDa "NASA - Picture of the Day", del giorno 21 Giugno 2009:"Today, the Sun will stay in the sky longer than any other day of the year, as seen from the Northern Hemisphere of Earth. Named the Summer Solstice, today's maximum daylight is indicative of the high amount of sunlight this time of year that is primarily responsible for the heat of the Summer season. At the North Pole and for all places above the arctic circle, there will be no night -- the entire day today will be lit by sunlight. The situation is reversed in Earth's Southern Hemisphere, where today has the least sunlight of any day. Today's solstice is commemorated above by a well-planned picture of our five billion year old Sun rising behind the 2500 year old Parthenon in Greece. Trees and birds occupy the foreground, while a modern crane is shown restoring parts of this historic symbol of a cultural civilization".MareKromium

Suns.jpgTwo Suns in the Sunset...246 visiteIn my rear view mirror, the Sun is going down
Sinking, behind bridges in the road...
And I think of all the good things
That we have left undone,
And I suffer premonitions,
Confirm suspicions,
Of the holocaust to come...
The rusty wire that holds the cork
That keeps the anger in,
Gives way,
And suddenly, it's day again!
The Sun is in the East,
Even though the day is done,
Two Suns in the sunset...
Hmmmmmmmmm....
Could be the Human Race is run?!?
Like the moment when your brakes lock
And you slide toward the big truck,
And stretch the frozen moments with your fear...
And you'll never hear their voices!
And you'll never see their faces!
You have no recourse to the law anymore!...
And as the windshield melts,
And my tears evaporate...
Leaving only charcoal to defend,
Finally I understand
The feelings of the few:
Ashes and Diamonds,
Foe and Friend,
We were all equal in the end...
(Pink Floyd - "Two Suns in the Sunset")MareKromium
