Longest Eclipse

On July 22 2009 the longest and brightest solar eclipse of the 21st century lasted for 6 minutes, 39 seconds. The shadow from the eclipse was only visible on the ground in certain regions across the Pacific and Indian oceans for a very brief period of time.

A mathematician from the Czech Republic and some of his colleagues were able to capture and composite 31 photographs from that day's events. The wispy lines visible around the moon are actually the sun’s corona.

Another solar eclipse of that magnitude is not expected until 2132.
