An Eclipse

sunvenusuv3A rare solar eclipse occurred last year. Usually it’s the Moon that eclipses the Sun. Last year, the planet Venus took its turn. The black dot in the picture is Venus crossing in front of the Sun. In this case, the Sun was imaged in three colors of ultraviolet light by the Earth-orbiting Solar Dynamics Observatory.  The dark region on the right of the Sun’s face is a large coronal hole.

As I said, these eclipses are rare. The next Venusian solar eclipse will occur in 2117.
