it’s been 30 years, but it’s back! the supermoon lunar eclipse is happening {9/27/15}…

The first “supermoon” lunar eclipse in more than three decades will grace Earth’s skies this month, as will a partial solar eclipse that most of the world will miss.

The supermoon total lunar eclipse, which occurs on Sept. 27, features a full moon that looks significantly larger and brighter than usual. It will be the first supermoon eclipse since 1982, and the last until 2033, NASA officials said in a newly released video.

A partial solar eclipse will take place two weeks before this special supermoon, on Sept. 13, but the earlier event will be visible only to skywatchers in southern Africa (as well as penguins, leopard seals and the other wildlife of Antarctica).

Supermoons” occur because the moon’s orbit around Earth is elliptical rather than circular. While the moon’s average distance from our planet is about 239,000 miles (384,600 kilometers), the natural satelite roams as far away as 252,000 miles (405,600 km) at “apogee” and gets as close as 226,000 miles (363,700 km) at “perigee.”

A supermoon is a full moon that occurs at, or very near, perigee and appears abnormally big in the sky as a result. In fact, supermoons appear about 14 percent larger and 30 brighter than apogee full moons, which are also known as “minimoons.”

Supermoon eclipses are special; they’ve occurred just five times since 1900 (in 1910, 1928, 1946, 1964 and 1982), NASA officials said in the new video. “Normal” lunar eclipses are much more common. In fact, an observer at any particular location around the globe can expect to see a total lunar eclipse about once every 2.5 years on average.

Lunar and solar eclipses are both caused by alignments of the moon, Earth and sun. In the case of a lunar eclipse, the Earth is the middle of this line and the moon passes into the planet’s shadow. But the moon doesn’t go completely dark during total eclipses; rather, it often turns a reddish hue because it’s hit by sunlight bent by Earth’s atmosphere. For this reason, total lunar eclipses are often referred to as “blood moons.”

With a solar eclipse, the moon is in the middle of the Earth-moon-sun line and blots out all or part of the solar disk from an Earth observer’s perspective.

If you live in southern Africa or plan to travel to the region to view the Sept. 13 partial solar eclipse, a word of warning: NEVER look at the sun without proper eye protection, even during an eclipse; serious and permanent eye damage can result.
