Umbra Fugax-1.jpgUmbra Fugax98 visiteSiamo al termine della spettacolare eclissi totale del 29 Marzo 2006 e l'ombra della Luna sta gi 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 - gi 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 cos: 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".

Sun Pillars.jpgLight Pillars' Parade88 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".

ALANBEAN-FANTASY.jpg"Buddies" forever114 visitePete Conrad, Dick Gordon and I were assigned by head astronaut Deke Slayton as the backup crew for Apollo 9. This was super news because this meant we would fly three missions subsequent and make one of the first Moon landings.
The most experienced astronaut was designated commander, in charge of all aspects of the mission including flying the lunar module. Prudent thinking suggested that the next most experienced crew member be assigned to take care of the command module since it had a heat shield and was our only way back home. This left the least experienced to accompany the commander. Pete Conrad had flown two Gemini flights, the second with Dick Gordon as his crew mate. I had not flown at all.
During training, Pete and I frequently practiced our lunar surface activities such as emplacing experiments, gathering rock samples, or making observations. We were excited. We were going to have the ultimative adventure someone in our profession could experience. But while we did, Dick Gordon would be orbiting 60 miles above us. We often fantasized Dick joining us on the Moon for all the fun, but we could never really find a way. But now I'm an artist and in my paintings I can have it my way. Now, at last, our best friend has come the last 60 miles.
One last story. Dick was the more experienced astronaut, yet I got the prize assignment. In the three years of training preceding our mission, he never once said: "It's not fair, I wish I could walk on the Moon too." I do not have his unwavering discipline or strength of character.

Moon and Companions~2.jpgHappy New Year from the Moon and Venus86 visiteDa "NASA - Picture of the Day" del 4 Gennaio 2006:"Fading sunlight, a young crescent Moon, and brilliant Venus shared the Western Sky in this view of 2005's final sunset from the top of Mount Haleakala, on Maui, Hawaii. Also known as the Sacred House of the Sun, Haleakala, is Maui's dormant volcano.
At 10.000 feet, the Summit is an ideal site for astronomical observatories, and this scene also features the silhouette of the Northern Hemisphere Faulkes Telescope. It can be of particular interest to students the fact that the Faulkes Telescope (a 2-meter diameter instrument, dedicated to astronomy education), can be remotely operated over the internet.
The Project is a joint effort between the Dill Faulkes Educational Trust and the University of Hawaii - Institute for Astronomy (...)".

PossibleImpacts.jpgIs "Something" going on?231 visiteUna piccola "provocazione", basata su dati oggettivi, che gi rimbalza nella mente di tantissimi Ricercatori ed Appassionati: sta succedendo qualcosa nel nostro Sistema Solare?
Un impatto certo (e recentissimo) su Giove; un possibile impatto su Venere; un Evento Ignoto su Marte (eruzione? Impatto?) ed un altro Evento Ignoto del quale - forse - parleremo in futuro.
Tutti eventi recenti, tutti eventi "imprevisti", tutti eventi - in s - molto violenti e potenzialmente sconvolgenti - se rivolti verso il nostro Pianeta.
La domanda semplice: sempre stato cos (solo che non ce ne accorgevamo, perch non avevamo i mezzi adeguati per "spiare" gli Eventi che occorrono nei recessi dei nostri Cieli), oppure qualcosa sta cambiando (o gi cambiata) negli Equilibri del Sistema Solare?
Se avete idee od opinioni, scrivete!MareKromium
