Rare Supermoon Lunar Eclipse Is Less Than A Week Away

On Sunday, September 27th, skywatchers will witness the grand finale of the rare lunar eclipse tetrad (series of four consecutive total lunar eclipses). And it promises to be quite a show. That's because this one involves a full moon and perigee. This means that the celestial body will be at its closest distance to earth, giving it a larger than life appearance. The last time the world witnessed this phenomenon was in 1982, and the next one will not be until 2033!
