'Supermoon' Lights Up Sky, Biggest In Nearly Two Decades

NASA/Bill Ingalls(NEW YORK) -- Did last night's rare "supermoon" live up to its hype? If the commentary online is any indication, those who had clear skies were not disappointed with the brilliant full moon that lit up the sky.

On Twitter, Facebook and Flickr, skywatchers around the world posted pictures and reactions to the biggest full moon in nearly decades.

During the so-called "supermoon," the moon wasn't just at its closest approach to Earth in its elliptical orbit, it was closer than it has been in 18 years.

After the sun set for East Coasters, #supermoon started trending on Twitter, as people started tweeting about the event. Many even uploaded snapshots of their supermoon views to the photo-sharing website Flickr.

"It's a bird- it's a plane- no, it's Supermoon!," said one Facebook user.

"the supermoon was super beautiful last night," posted another.

Full moons come in different sizes because of the elliptical shape of the moon's orbit -- one side of the ellipse is about 31,000 miles closer to Earth than the other. When the moon is closest to Earth (at its perigee), it is 14 percent larger and 30 percent brighter than when it's farthest from the planet (at its apogee).

For weeks, Saturday's so-called "supermoon" sparked interest online, with astrologers and amateur astronomers speculating that the extra-large full moon could lead to unusual weather. After Japan's earthquake, some even wondered if the supermoon contributed to the event.

Scientists emphasize that there is no connection between the moon's position and extreme weather or natural disasters here on Earth.

Super Full Moon to Grace Skies Saturday

Gaye Gerard/Getty Images(WASHINGTON) -- When you step outside Saturday night, don't forget to take a good look up at the sky. Assuming clouds don't get in the way, you'll get to gaze at the biggest full moon in nearly two decades.

During what some sky watchers are calling the "supermoon," the moon won't just be at its closest approach to Earth in its elliptical orbit, it will be closer than it has been in 18 years.

"It's going to be big and really bright," said NASA astronomer Dave Williams. "It should be noticeably brighter than a normal full moon."

Full moons come in different sizes because of the elliptical shape of the moon's orbit -- one side of the ellipse is about 31,000 miles closer to Earth than the other.

For weeks, the rare full moon has sparked interest online, with astrologers and amateur astronomers speculating that the "supermoon" could lead to unusual weather. After Japan's earthquake, some even wondered if the supermoon contributed to the event.

In a post earlier this month, AccuWeather blogger Mark Paquette said the phrase "supermoon" originated on the website of astrologer Richard Nolle and spread to astronomers online. According to Nolle's definition, a new or full moon at 90 percent or more of its perigee (or closest approach to Earth) qualifies as a "supermoon." Saturday's full moon won't just be a supermoon but an extreme supermoon, he said, because the moon will be almost precisely at its closest distance to Earth.

According to "new age" forecasts, he said, the supermoon brings strong earthquakes, storms or unusual climate patterns. Scientists emphasize that there is no connection between the moon's position and extreme weather or natural disasters (like Japan's earthquake) here on Earth.
