Hum Posted May 14, 2012 Share Posted May 14, 2012 Just two weeks after the huge "supermoon" wowed skywatchers around the world, the heavens will offer up another observing treat ? a solar eclipse on May 20 that should be visible from much of western North America. The May 20 event is what's known as an annular solar eclipse, in which the moon blocks out most of the sun but leaves a ring of light visible around its circumference. It should be quite a spectacular sight for favorably placed ? and appropriately careful ?skywatchers throughout Asia, the Pacific region and parts of North America. As the moon revolves around Earth, it passes between our planet and the sun once every 29.5 days. Most of the time,the moon zips either above or below the sun, and no eclipse occurs. source Link to comment Share on other sites More sharing options...

DocM Posted May 14, 2012 Share Posted May 14, 2012 Beause the vast majority of astronomic & spacecraft imagers (ex: Hubble, Voyager, Galileo etc.) are B&W as they give higher resolution than color imagers and are more sensitive in low light. They also have a greater dynamic range - meaning more shades, which lets you see deeper into shadows and bright areas in the same shot. To get color they take 3 B&W images, each with a color filter, then combine them in software. Sometimes this is done simultaneously with 3 different filtered imagers and a B&W. That or they use false color, assigning a different color to each shade of grey. Link to comment Share on other sites More sharing options...
