Fantasy APOD.jpgThe Universe is "on sight"!116 visiteDa "NASA - Picture of the Day" del 16 Giugno 2006:"The first APOD appeared 11 years ago today, on 1995, June 16. Although garnering only 14 page views on that day, we are proud to estimate that APOD has now served over 400 million space-related images over the last 11 years. That early beginning, along with a nearly unchanging format, has allowed APOD to be a consistent and familiar site on a web frequently filled with change. Many people don't know, though, that APOD is now translated daily into many major languages. We again thank our readers and NASA for their continued support, but ask that any potentially congratulatory e-mail go to the folks who created the great pictures - many times with considerable effort - that APOD has been fortunate enough to feature over the past year. Many can be contacted by following links found in the credit line under the image. Some of these images are featured in the above spectacular collage of a fantasy sky above Mars submitted by an enthusiastic APOD reader skilled in digital image manipulation. How many APOD images can you identify?".

Glory.jpgGlory never fades...116 visiteIf you tried to enter this hall of fog, you would find it dissipates around you. The hall is actually an the mountain from which this picture was taken.
Known as "The Glory", the phenomenon is frequently seen from airplanes. The ring's center is not visible, but if it were, the shadow of the observer would appear. This shadow would likely change as clouds passed, creating a faux moving giant known as the Brocken Spectre.
Pictured above, several concentric rings of the glory appear to create a hall for this mountain king. The cause of The Glory has only been understood recently and is relatively complex. Briefly, small droplets of water reflect, refract, and diffract Sunlight backwards towards the Sun. The phenomenon has a counterpart in astronomy, where looking out from planet Earth in the direction opposite the Sun yields a bright spot called "The Gegenschein".MareKromium

ALANBEAN-FANTASY.jpg"Buddies" forever114 visitePete Conrad, Dick Gordon and I were assigned by head astronaut Deke Slayton as the backup crew for Apollo 9. This was super news because this meant we would fly three missions subsequent and make one of the first Moon landings.
The most experienced astronaut was designated commander, in charge of all aspects of the mission including flying the lunar module. Prudent thinking suggested that the next most experienced crew member be assigned to take care of the command module since it had a heat shield and was our only way back home. This left the least experienced to accompany the commander. Pete Conrad had flown two Gemini flights, the second with Dick Gordon as his crew mate. I had not flown at all.
During training, Pete and I frequently practiced our lunar surface activities such as emplacing experiments, gathering rock samples, or making observations. We were excited. We were going to have the ultimative adventure someone in our profession could experience. But while we did, Dick Gordon would be orbiting 60 miles above us. We often fantasized Dick joining us on the Moon for all the fun, but we could never really find a way. But now I'm an artist and in my paintings I can have it my way. Now, at last, our best friend has come the last 60 miles.
One last story. Dick was the more experienced astronaut, yet I got the prize assignment. In the three years of training preceding our mission, he never once said: "It's not fair, I wish I could walk on the Moon too." I do not have his unwavering discipline or strength of character.

Iridescent_Cloud.jpgIridescent Cloud114 visiteCaption NASA:"Why would a cloud appear to be different colors? A relatively rare phenomenon known as "Iridescent Clouds" can show unusual colors vividly or a whole spectrum of colors simultaneously. These clouds are formed of small water droplets of nearly uniform size. When the Sun is in the right position and mostly hidden by thick clouds, these thinner clouds significantly diffract sunlight in a nearly coherent manner, with different colors being deflected by different amounts. Therefore, different colors will come to the observer from slightly different directions. Many clouds start with uniform regions that could show iridescence but quickly become too thick, too mixed, or too far from the Sun to exhibit striking colors.
This iridescent cloud was photographed above Boulder, Colorado last week".MareKromium
