Noah Petro, a scientist at NASA's Goddard Space Flight Center, said not every place on the globe was lucky enough to catch a glimpse of the celestial event. North America and most of the Pacific region were unable to see it. /VCG Photo

Astronomy lovers used telescopes or went to nearby observatories to watch the eclipse. The next lunar eclipse of such length is due in 2123. /VCG Photo
