The Moon will became full on February 27th and this full Moon is special because it?s the biggest and brightest of the year. ?Not all full Moons are alike,? says astronomy professor George Lebo. ?Sometimes pollution or volcanic ash shades them with interesting colors. Sometimes haloes form around them — a result of ice crystals in the air. This full Moon is unique in another way. It will be closer to Earth than usual.

?The moon’s orbit around our planet is not a perfect circle,? says Lebo. ?It?s an ellipse.? At one end of the ellipse (called apogee) the Moon is farthest away from Earth, and at the other end (called perigee) the Moon is closest to us.

Wednesday?s full moon was near perigee and appeared 9% wider than normal and shone 20% brighter.

A severe meteor storm expected to peak in November will bombard the world?s satellites with an unusually dense amount of space dust, creating the greatest threat of a meteor impact since 1966, according to NASA scientists.

The Leonid meteor shower occurs annually but this year it is expected to be a storm unlike anything seen in recent decades. The last time the Leonids produced what astronomers call a storm, only a handful of satellites orbited the Earth, so the threat was minimal.

Now there are hundreds of satellites that will be at risk. They provide services ranging from pagers and television to weather forecasts and monitoring for potential nuclear blasts from other nations.

Comets and asteroids have been blamed for bringing life to Earth in the form of bacteria and wiping out the dinosaurs. Now scientists say they may also be responsible for sex.

The origin of sex remains one of biology?s greatest mysteries. Scientists can?t say exactly why we do it. Before sex, life seemed to manage fine with asexual reproduction. Researchers Claus Wilke and Chris Adami of Caltech and NASA?s Jet Propulsion Laboratory have used digital organisms to simulate life before sex and reveal a possible mechanism for the start of sex.
