ikenbot: Moon, Venus, & The Sun “The Moon and Venus displayed very similar phases yesterday (23 May) almost looking like twins, one heading for the Sun, the other having just performed a remarkable transit wich resulted in the annular eclipse 2 days ago. The Moon (30’) is still 2 arc minutes smaller than the Sun (32’). The sizes of the 3 bodies are correct but of course not their relative positions. Everything is shot in daylight so I have enhanced the contrast for the Moon and Venus.” — Peter Rosén

cwnl: Sunrise, Moonrise by Robert Pölzl For many Europeans, the Sun and New Moon rose together on January 4th of 2011 in a partial solar eclipse. Arriving close on the heels of the new year, it was the first of a series of four(!) partial solar eclipses that were due in 2011. This composite image documents the graceful celestial event in colorful morning skies over Graz, Austria.

geologise: Saturday’s Lunar Eclipse Will Include ‘Impossible’ Sight(Photo by Images In The Backcountry on Flickr) This year’s second total lunar eclipse on Saturday (Dec. 10) will offer a rare chance to see a strange celestial sight traditionally thought impossible. For most places in the United States and Canada, there will be a chance to observe an unusual effect, one that celestial geometry seems to dictate can’t happen. The little-used name for this effect is a “selenelion” (or “selenehelion”) and occurs when both the sun and the eclipsed moon can be seen at the same time. But wait!  How is this possible? When we have a lunar eclipse, the sun, Earth and moon are in a geometrically straight line in space, with the Earth in the middle. So if the sun is above the horizon, the moon must be below the horizon and completely out of sight (or vice versa). And indeed, during a lunar eclipse, the sun and moon are exactly 180 degrees apart in the sky; so in a perfect alignment like this (a “syzygy”) such an observation would seem impossible.  But it is atmospheric refraction that makes a selenelion possible. Atmospheric refraction causes astronomical objects to appear higher in the sky than they are in reality. Read the full article from SPACE.com omg friends in the US go see this for me sdjfjsdk
