FaithFullMoon090409_westlake.jpgObscuring the Moon...56 visiteCaption NASA:"October's bright Full Moon is also known as the "Harvest Moon".
Traditionally, the Harvest Moon is the Full Moon closest to the Autumnal Equinox. But in this snapshot, the Full Moon could be called the "Old Faith-Full Moon".
Taken on September 4, 2009, the picture combines the regularly occurring lunar phase with Old Faithful Geyser in Yellowstone National Park, named for its dependable eruptions.
Shining on the well-known geyser's towering pillar from behind, the moonlight creates an eerie halo surrounding convoluted shapes.
Faithfully, the Full Moon itself is bright enough to be seen through the dense swirling steam near the top".MareKromium

TheGreyIllusion.JPGThe "Same Color Illusion"56 visiteDa "NASA - Picture of the Day" del giorno 4 Ottobre 2009:"Are square A and B of the same color?
They are.
The above illusion, called the "Same Color Illusion", illustrates that purely human observations in science may be ambiguous or inaccurate. Even such a seemingly direct perception as relative color. Similar illusions exist on the sky, such as the size of the Moon near the Horizon, or the apparent shapes of astronomical objects. The advent of automated, reproducible, measuring devices such as CCDs have made science in general and astronomy in particular less prone to, but not free of, human-biased illusions".MareKromium

Earth.pngMother Earth56 visiteDalla Rubrica "NASA - Picture of the Day", del giorno 23 Novembre 2009:"Goodbye Earth!
Earlier this month, ESA's interplanetary Rosetta Spacecraft zoomed past the Earth on its way back across the Solar System.
Pictured above, Earth showed a bright crescent phase featuring the South Pole to the passing rocket ship. Launched from Earth in 2004, Rosetta used the gravity of the Earth to help propel it out past Mars and toward a 2014 rendezvous with Comet Churyumov-Gerasimenko.
Last year, the Robot Spacecraft passed asteroid 2867 Steins, and next year it is scheduled to pass enigmatic asteroid 21 Lutetia. If all goes well, Rosetta will release a probe that will land on the 15-Km diameter comet in 2014". MareKromium

Eyjafjallajökull-Fulle.jpgNight over Eyjafjallajökull (credits: Marco Fulle - Stromboli Online) 56 visiteWhy did the recent volcanic eruption in Iceland create so much ash? Although the large ash plume was not unparalleled in its abundance, its location was particularly noticeable because it drifted across such well populated areas.
The Eyjafjallajökull Volcano in southern Iceland began erupting on March 20, with a second eruption starting under the center of a small glacier on April 14, 2010. Neither eruption was unusually powerful. The second eruption, however, melted a large amount of glacial ice which then cooled and fragmented lava into gritty glass particles that were carried up with the rising Volcanic Plume.
Pictured above, lightning bolts illuminate ash pouring out of the Eyjafjallajökull Volcano.MareKromium
