SunriseovertheParthenon.jpgDawn over the Land of Gods67 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

Triple_Sunrise.jpgTriple Sunrise67 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

TheGreyIllusion.JPGThe "Same Color Illusion"67 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

Venus.jpgDaytime Venus66 visiteDa "NASA - Picture of the Day" del giorno 9 Aprile 2009:"This remarkable picture of a slender crescent Venus was made during daylight hours on March 26, 2009.
Venus was then very near Inferior Conjunction, its closest approach to a point on a line directly between Earth and the Sun. So, daylight was a good time to carefully record the telescopic view when both Venus and Sun were high in the daytime sky.
Near Inferior Conjunction, Venus is closest to us and at its largest apparent size, but Venus is also strongly backlit by Sunlight, presenting its night side partially outlined by a narrow crescent.
What makes the image remarkable are the faint arcs extending beyond the sunlit crescent around to the night side of Venus, due to sunlight filtering through the Planet's dense Atmosphere.
Astronomer Eddie Guscott reports from his site in Essex, England, that the faint extensions came and went as the Earth's atmospheric blurring changed. His image was constructed from 85 of the sharpest frames chosen from thousands taken with a webcam and telescope".MareKromium

Aurora_Borealis~0.jpgAuroral Corona66 visiteCaption NASA, da "NASA - Picture of the Day" del giorno 28 Luglio 2009:"Few Auroras show this level of detail. Above, a standard digital camera captured a particularly active and colorful Auroral Corona that occurred last week above Alberta, Canada. With a shape reminiscent of a flower, the spectacular Aurora had an unusually high degree of detail. The vivid green and purple auroral colors are caused by high Atmospheric Oxygen and Hydrogen reacting to a burst of incoming electrons. Many photogenic Auroras have been triggered from a Solar Wind Stream that recently passed the Earth. The Auroras were unexpected because the initiating Sun has been unusually quiet lately".MareKromium
