Annular solar eclipse observed by Hinode (w/ Video)

January 10, 2011 By Janet Anderson

On January 4, the Hinode satellite captured these breathtaking images of an annular solar eclipse.

An annular eclipse occurs when the , slightly more distant from Earth than on average, moves directly between Earth and the sun, thus appearing slightly smaller to observers’ eyes; the effect is a bright ring, or annulus of sunlight, around the silhouette of the moon. Hinode, a Japanese mission in partnership with NASA, NAOJ, STFC, ESA, and NSC, currently in Earth orbit, is studying the Sun to improve our understanding of the mechanisms that power the solar atmosphere and drive solar eruptions.
