The first of four lunar eclipses known as the "blood moons" will take place on Tuesday and those living in the U.S. are in for a treat.
"The most unique thing about the 2014-2015 tetrad is that all of them are visible for all or parts of the USA," said NASA expert Fred Espenak on Nasa.gov. A tetrad is a series of four consecutive total eclipses that take place at six month intervals.
Tuesday's eclipse starts at 2 a.m. EST, according to NASA, when the edge of the moon will enter the core of the earth's shadow. Total eclipse will occur at around 3 a.m. for those on the East Coast and at around midnight for those in the west. The event will last about 78 minutes, according to NASA.
A total eclipse takes place when the earth casts a shadow on a full moon. The sunlight on the earth's surface shows up on its shadow and gives the moon a red, coppery glow.
Three more total eclipses are expected on Oct. 8, 2014, April 4, 2015 and Sept. 28, 2015.
