AuroraBorealis-Alaska.jpgAurora over Alaska86 visiteCaption NASA:"Higher than the highest mountain, higher than the highest airplane, lies the realm of the aurora. Aurora rarely reach below 60 Km, and can range up to 1000. Aurora light results from solar shockwave causing energetic electrons and protons to striking molecules in the Earth's atmosphere. Frequently, when viewed from space, a complete aurora will appear as a circle around one of the Earth's magnetic poles. The above digitally enhanced photograph was taken in 2005 January shows a spectacular aurora borealis above the frozen landscape of Bear Lake, Alaska, USA.
The above image was voted Wikipedia Commons Picture of the Year for 2006".

Earth_Eclipse.jpgThe "Diamond Ring"...from the Moon!99 visiteUno splendido montaggio che ci mostra una ipotetica veduta dalla Luna di un Eclisse Totale di Sole. Bellissima ricostruzione, davvero, ma...c' un errore davvero grande in questa "Scena di fantasia": durante una eclissi totale di Sole (ed anche nel momento in cui si forma l'Anello di Diamante - come in questa immagine) la superficie della Luna si troverebbe immersa nella pi totale oscurit e quindi risulterebbe ai nostri occhi solo appena distinguibile, in forma di vaghe e quasi indefinibili ombre scure, con le stelle ben visibili nel cielo.
Ma va bene lo stesso...
Caption NASA:"Parts of Saturday's (March 3) lunar eclipse will be widely visible. For example, skywatchers in Europe, Africa, and western Asia will be able to see the entire spectacle of the Moon gliding through Earth's shadow, but in eastern North America the Moon will rise already in its total eclipse phase. Of course if you traveled to the Moon's near side, you could see the same event as a solar eclipse, with the disk of our fair planet Earth completely blocking out the Sun. For a moon-based observer's view, graphic artist Hana Gartstein (Haifa, Israel) offers this composite illustration. In the cropped version of her picture, an Apollo 17 image of Earth is surrounded with a red-tinted haze as sunlight streams through the planet's dusty atmosphere. Earth's night side remains faintly visible, still illuminated by the dark, reddened Moon, but the disk of the Earth would appear almost four times the size of the Sun's disk, so the faint corona surrounding the Sun would be largely obscured. At the upper left, the Sun itself is just emerging from behind the Earth's limb".MareKromium

ZZ-ZZ-ZZ-Venus_and_the_Moon.jpgCrescent Venus and crescent Moon from Budapest87 visiteDa "NASA - Picture of the Day" del 30 Ottobre 2006:"There's something behind these clouds. Those faint graceful arcs, upon inspection, are actually far, far in the distance. They are the Earth's Moon and the planet Venus.
Both the Moon and Venus are bright enough to be seen during the day, and both are quite capable of showing a crescent phase. To see Venus, which appears quite small, in a crescent phase requires binoculars or a telescope.
In the above dramatic daytime image taken from Budapest, Hungary, the Moon and Venus shared a similar crescent phase a few minutes before the Moon eclipsed the larger but more distant world.
About an hour later, Venus reappeared".

Moon and Pleiades.jpgOld Moon...85 visiteDa "NASA - Picture of the Day" del 29 Giugno 2006:"An old crescent Moon shares the Eastern Sky over Menton, France, with the Sister Stars of the Pleiades cluster in this early morning skyscape recorded just last Friday, June 23rd. (Bright Venus was also near the Eastern horizon, but is not pictured here.) Astronomical images of the well-known Pleiades often show the cluster's alluring blue reflection nebulae, but they are washed out here by the bright moonlight. Still, while the crescent Moon is overexposed, surface features can be seen on the dim lunar night side illuminated by earthshine - light from sunlit planet Earth. Of course, you can spot a young crescent Moon in the early evening sky tonight.
Having left the Pleiades behind, a lovely lunar crescent now appears in the West, lining up with planets Mars, Saturn and Mercury along the Solar System's Ecliptic Plane".

Moon from Hawaii.jpgHaleakala's Moon101 visiteDa "NASA - Picture of the Day" del 10 Giugno 2006:"A waxing crescent Moon shines over the caldera of dormant volcano Haleakala and observatory domes in this dramatic view from above the clouds.
Looking West from Maui, Hawaii on May 31st, the scene also records the lights of Honolulu on the horizon. Near the strongly overexposed crescent, is bright planet Saturn, but included in the skyscape are planet Mars and the Gemini stars Castor and Pollux.
Of course, skywatchers also found star cluster M 44, The Beehive Cluster, in this early evening sky, wedged between Saturn and the Moon. In fact, as it closes with Saturn, Mars will pass in front of the Beehive on June 15, so just keep looking West".
