Perigree Moon
Last month's full Moon over many viewpoints was particularly radient, and it looked bigger than usual. That's because it was the biggest full Moon of 2008 a perigee Moon, 14% wider and 30% brighter than the smallest full Moons of the year.
It's going to happen again at the beginning of 2009.
On Saturday night, Jan. 10th, another perigee Moon is coming. It's the biggest full Moon of 2009, almost identical to the one that impressed onlookers in Dec. 2008.
Johannes Kepler explained the phenomenon 400 years ago. The Moon's orbit around Earth is not a circle; it is an ellipse, with one side 50,000 km closer to Earth than the other. Astronomers call the point of closest approach "perigee," and that is where the Moon will be this weekend.
Perigee full Moons come along once or twice a year. 2008 ended with one and now 2009 is beginning with another.
Another magic moment happens when the perigee Moon is near the horizon. That is when illusion mixes with reality to produce a truly stunning view. For reasons not fully understood by astronomers or psychologists, low-hanging Moons look unnaturally large when they beam through trees, buildings and other foreground objects. This weekend, the "Moon illusion" will amplify a full Moon that's extra-big to begin with because of the Parigree
At perigee, the Moon is only 360,000 km away!

Orion Nebula
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, by beginners in Astronomy as well as professionals in the field. That's because the Orion Nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers and beginners have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the Orion Nebula.

Harvest Moon
There's been a harvest moon recently, followed by a strange first quarter that puzzled some amateur astronomers but it's perfectly normal for this time of year.
