Blood Moon

The blood moon was visible during a total lunar eclipse, when Earth cast its shadow over the moon. This photo was taken by CIERA graduate student Imran Sultan, amateur astrophotographer and member of Professor Claude-André Faucher-Giguère‘s research group.

Sultan photographed the entire event, which lasted about four hours early Friday morning (12-4am), using a refractor telescope and DSLR camera.

During a lunar eclipse, when it is totally eclipsed by the Earth, the Moon takes on a reddish color that is caused by the planet when it completely blocks direct sunlight from reaching the Moon’s surface. The only light that is reflected from the Moon is what has been refracted by the Earth’s atmosphere.
