Solstice over Stonehenge.jpgSolstice on Stonehenge76 visiteDa "NASA - Picture of the Day" del 21 Giugno 2006:"Today the Sun reaches its northernmost point in the planet Earth's sky.
Called a "solstice", the date traditionally marks a change of seasons -- from Spring to Summer in Earth's Northern Hemisphere and from Fall to Winter in Earth's Southern Hemisphere. Pictured above is the 2005 Summer Solstice celebration at Stonehenge in England. The event was rare because Stonehenge was not always open to the public, and because recent Summer Solstices there had been annoyingly cloudy.
In 2005, however, thousands of people gathered at sunrise to see the sun rise through the 4000 year old solar monument.
Due to the precession of the Earth's orbital axis over the millennia, the Sun no longer rises over Stonehenge in an astronomically significant way, although the photographer was able to find a good spot where the rising Sun appeared over one of Stonehenge's massive standing stones".Giu 22, 2006

Fantasy APOD.jpgThe Universe is "on sight"!82 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?".Giu 16, 2006

SunDogs.jpgSuomi's Sundogs66 visiteWhat's happened to the Sun? Sometimes it looks like the Sun is being viewed through a large lens. In the above case, however, there are actually millions of lenses: ice crystals. As water freezes in the upper atmosphere, small, flat, six-sided, ice crystals might be formed. As these crystals flutter to the ground, much time is spent with their faces flat, parallel to the ground. An observer may pass through the same plane as many of the falling ice crystals near sunrise or sunset. During this alignment, each crystal can act like a miniature lens, refracting sunlight into our view and creating phenomena like parhelia, the technical term for sundogs. The above image was taken during early 2006 February near Helsinki, Finland with a quickly deployed cellular camera phone. Visible in the image center is the Sun, while two bright sundogs glow prominently from both the left and the right. Also visible is the 22° halo also created by sunlight reflecting off of atmospheric ice crystals. Giu 13, 2006

Moon from Hawaii.jpgHaleakala's Moon83 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".Giu 10, 2006
