On May 9, 2016, Mercury passed directly between the sun and Earth. This event – which happens about 13 times each century – is called a transit. NASA’s Solar Dynamics Observatory, or SDO, studies the sun 24/7 and captured the entire seven-and-a-half-hour event. This composite image of Mercury’s journey across the sun was created with visible-light images from the Helioseismic and Magnetic Imager on SDO.

Less than once per decade, Mercury passes between the Earth and the sun in a rare astronomical event known as a planetary transit. The 2016 Mercury transit occurred on May 9th, between roughly 7:12 a.m. and 2:42 p.m. EDT.
