Solar_Eclipse_1999-MIR.jpgMacular Degeneration on a Planetary Scale146 visiteCaption NASA, from "NASA - Picture of the Day" del giorno 2 Gennaio 2011:"Here is what the Earth looks like during a Solar Eclipse.
The shadow of the Moon can be seen darkening part of Earth. This shadow moved across the Earth at nearly 2000 Km-per-hour.
Only observers near the center of the dark circle can see a Total Solar Eclipse - others see a Partial Eclipse where only part of the Sun appears blocked by the Moon.
This spectacular picture of the 1999 August 11 Solar Eclipse was one of the last ever taken from the Mir Space Station. The two bright spots that appear on the upper left are thought to be Jupiter and Saturn. Mir was deorbited in a controlled re-entry in 2001".MareKromiumGen 06, 2011

Solar_Green-Flash.jpgA "Green Flash" from the Sun88 visiteDalla Rubrica "NASA - Picture of the Day" del giorno 4 Gennaio 2011:"Many people think it is just a myth. Others think it is true but its cause isn't yet known. Adventurers pride themselves on having seen it.
What is it?
It's a "Green Flash" from the Sun. The truth is the Green Flash does exist and its cause is well understood.
Just as the setting Sun disappears completely from view, a last glimmer appears startlingly green.
The effect is typically visible only from locations with a low, distant horizon, and lasts just a few seconds. A Green Flash is also visible for a rising Sun, but takes better timing to spot.
A dramatic Green Flash, as well as an even more rare Blue Flash, was caught in the above photograph recently observed during a Sunset visible from Teide Observatory at Tenerife, Cannary Islands, Spain.
Obviously, the Sun does not partly turn either green or blue: the effect is caused by different layers of the Earth's Atmosphere, together acting like a prism".MareKromiumGen 05, 2011
