Incredible scenes show the Sun playing peak-a-boo with a spacecraft as the Moon eclipses the star.

NASA's Solar Dynamics Observatory (SDO) witnessed a rare double eclipse as first the Moon and then the Earth passed between its instruments and the Sun on July 25.

The Moon’s transit, the deepest of the year so far, briefly blocked up to 62% of the solar disc, leaving a sharp shadow.

Just hours later, the Earth followed suit, albeit less dramatically as a spectacle, as it completely obscured the Sun for over ninety minutes.

Double eclipses like this are extremely rare, last seen in 2015 and 2016 from the SDO’s viewpoint.

SDO is about 93 million miles (150 million kilometers) away from the Sun. It orbits the Earth at about 22,245 miles (35,790 kilometers) above the surface, so it stays roughly the same distance from the Sun as the Earth does. This position helps it keep a steady view of the Sun.
