Perseid-2.jpgShooting Star (2) - detail mgnf84 visiteOsservate questo ingrandimento della Perseide immortalata dal nostro Amico Jimmy Westlake e poi provate a riguardare il (presunto) bolide che Cassini potrebbe aver fotografato nello Spazio di Saturno: noterete con semplicità che le caratteristiche delle due "strisciate di luce" (streaks) sono MOLTO simili.
Peccato che la NASA si affanni a dare credito solo ad alcuni personaggi e ad alcune (sempre più discutibili o insulse) "scoperte" (come il presunto colorito "rosato" di Iperione), senza mai prendere atto che anche in Italia esistono Ricercatori attenti e competenti i quali, di tanto in tanto, sono i primi a notare l'esistenza di qualcosa di veramente raro...
Peccato.

ALANBEAN-CORETUBE.jpgCore-Tube117 visiteDalla Galleria Pittorica dell'Astronauta Alan Laverne Bean: un Omaggio alla Luna ed a quei pochi che ebbero il coraggio, la fortuna ed il privilegio di camminarci sopra.
Ma lasciamo che sia "Alan" a raccontarci questa storia: la "Sua Storia"...
"...When my book, "Apollo, An Eyewitness Account", was published in October of 1998, I felt an overall sense of satisfaction. I was, in fact, preserving some of my special memories of the Apollo Program. This was the reason I resigned from NASA to become an artist.
I was moving right along but I noticed my goals for the future were even more ambitious. I wanted to paint the Moon more beautifully than I had done so far, as colorful as it could be painted, and still look like the Moon to me, a worthy but elusive goal.
I stopped painting commissions and began painting several series of studies to explore and develop new color techniques and combinations. This intense and dedicated effort consumed me for the better part of a year with the resulting changes first coming to full fruition in this painting.
Sometimes when I look at this painting I wonder if the changes were all that much. I question if anyone other than me can see them or even care? I don't know. Was it worth the time? I hope so...".

Aurora Borealis~0.jpgAurora Borealis over North Dakota81 visiteDa "NASA - Picture of the Day" del 20 Novembre 2005:"This aurora was a bit of a surprise. For starters, on this Friday morning in August 2002, no intense auroral activity was expected at all. Possibly more surprising, however, the aurora appeared to show an usual structure of green rays from some locations. In the above image, captured from North Dakota, USA, a picket fence of green rays stretches toward the horizon. Mirroring the green rays is a red band, somewhat rare in its own right. Lights from the cities of Bismarck and Mandan are visible near the horizon. Large sunspot groups indicate that activity from an active Sun is relatively likely, possibly causing other streams of energetic particles to cascade onto the Earth and so causing more auroras".

Moonrise.jpgThe "Moon Illusion"...From Cape Sounion213 visiteDa "NASA - Picture of the Day" del 23 Giugno 2005:"The Moon was full this month on June 22nd, only a day after the northern hemisphere's summer solstice. Since this solstice marked the northernmost point of the Sun's annual motion through planet Earth's sky, the full Moon rising near the ecliptic plane opposite the Sun was at its farthest south for the year. Only a month earlier, on May 23rd, astronomer Anthony Ayiomamitis recorded this picture of another southerly full Moon rising above Cape Sounion, Greece. The twenty-four hundred year old Temple of Poseidon lies in the foreground, also visible to sailors on the Aegean Sea. In this well-planned, single exposure, a long telephoto lens makes the Moon loom large, but even without optical aid casual skygazers often find the full Moon looking astonishingly large when seen near the horizon.
That powerful visual effect is known as the Moon Illusion".

Sun_Pillar_in_blue_and_violet.jpgSun Pillar from Lake Tahoe - Nevada State Park (USA)127 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_Pillar.jpgA light "Sun-pillar" from somewhere in USA100 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".
