The_Sun.jpgPartial Eclipse57 visiteCaption NASA:"On Monday, March 19, 2007, shortly before the Equinox, locations in Asia and the Arctic were favoured by the New Moon's shadow during a partial Solar Eclipse. Although the view from Goa, India, found the eclipsed Sun near the horizon, photographer Joerg Schoppmeyer was still able to capture this lovely image, combining celestial with terrestrial silhouettes.
The next eclipse season will begin in late August this year, featuring a total Lunar Eclipse on August 28, and another partial solar eclipse on September 11. Compared to the March 19th eclipse, the September 11th eclipse will be seen on the other side of our fair planet, from parts of South America and Antarctica".

FL-Anticrepuscolar Rays.jpgInfinite60 visiteCaption NASA originale:"(...) Pictured above are anticrepuscular rays.
To understand them, start by picturing common crepuscular rays that are seen any time that Sunlight pours though scattered clouds. Now although Sunlight indeed travels along straight lines, the projections of these lines onto the spherical sky are great circles. Therefore, the crepuscular rays from a setting (or rising) Sun will appear to re-converge on the other side of the sky.
At the anti-solar point 180° around from the Sun, they are referred to as anticrepuscular rays (...)".

M 31 and Hale Bopp.jpgTemporary Sky...57 visiteDa "NASA - Picture of the Day" del 13 Agosto 2006:"The Moon almost ruined this photograph. During late March and early April 1997, Comet Hale-Bopp passed nearly in front of the Andromeda Galaxy.
Here the Great Comet of 1997 and the Great Galaxy in Andromeda were photographed together on 1997 March 24th. The problem was the brightness of the Moon. The Moon was full that night and so bright that long exposures meant to capture the tails of Hale-Bopp and the disk of M31 would capture instead only moonlight reflected off the Earth's atmosphere. By the time the Moon would set, this opportunity would be gone. That's why this picture was taken during a total lunar eclipse".

Skylab-1973.jpgThe "unforgettable" Skylab...80 visiteDa "NASA - Picture of the Day", del 29 Aprile 2006:"Skylab was an orbiting laboratory launched by NASA in May 1973. Skylab, pictured above, was visited 3 times by NASA Astronauts who sometimes stayed as long as two and a half months. Many scientific tests were performed on Skylab, including astronomical observations in ultraviolet and X-ray light. Some of these observations yielded valuable information about Comet Kohoutek, our Sun and about the mysterious X-ray Background Radiation that (apparently) comes from all over the sky.
Skylab fell back to Earth on July, 11, 1979".

ALANBEAN-FANTASY.jpg"Buddies" forever95 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.

ZO-Westlake3Planets061905.jpgMercury, Venus and Saturn in the Western Sky66 visiteDa "NASA - Picture of the Day" del 24 Giugno 2005:" This weekend three planets will grace the Western Sky, forming a lovely trio easily visible shortly after sunset. Saturday evening in particular will find Saturn, Venus and Mercury all within a 2° circle (about the size of your thumb held at arm's length) above the Western Horizon. Recorded last Sunday, June 19, this image shows the same 3 planets arrayed along the ecliptic plane above a Colorado Rocky Mountain skyline. Venus is easiest to pick out of the twilight, the brightest celestial beacon below picture center, with Saturn above and to the left of Venus and Mercury closest to the horizon, right of prominent Pinnacle Peak. By Saturday, the wandering planets will draw even closer together (...)".
