During last night’s total eclipse of the moon, Earth’s shadow brushed the moon’s face. The eclipse is over, but, just like you or me, Earth still casts a shadow.

A solar eclipse happens at the new moon – when the moon passes between the sun and Earth. A lunar eclipse happens when the Earth, sun and moon align in space, with Earth in the middle. Why aren’t there eclipses at every full and new moon?
During a lunar eclipse, you’ll see the Earth’s shadow creeping across the moon’s face.

According to the definition of supermoon coined by Richard Nolle 30 years ago, the year 2015 has a total of six supermoons. They are the new moons of January, February and March and the full moons of August, September and October. The September 28, 2015 full moon – which will feature a total eclipse – will be the closest supermoon of 2015.
