Rare Planetary Lunar Occultation (PLO) in December

Those of you who follow popular science news in the papers may be aware that a few years ago Mars was remarkably close to the earth in a once in a lifetime event. Here's an e-mail explaining it from back then: *Two moons on 27 August* 27th Aug the Whole World is waiting for...* Planet Mars will be the brightest in the night sky starting August. It will look as large as the full moon to the naked eye. This will cultivate on Aug. 27 when Mars comes within 34.65M miles of earth. Be sure to watch the sky on Aug. 27 12:30 am. It will look like the earth has 2 moons. The next time Mars may come this close is in 2287. Share this with your friends as NO ONE ALIVE TODAY will ever see it again.

He studied Nuclear Winter and the conditions on Venus. And, more than anyone else, he kindled the love of science. In 1980 PBS released Cosmos - a personal journey discovering the universe with science. I'm not sure when exactly I saw it - but I think it was on an old black and white TV (that's right kids - they didn't always come in colour 3D) in the back room of our old rental house in outback New South Wales. Each Sunday I'd wait eagerly for the next episode and marvel at the wonders of space and the Earth. Tonight I took a break from my hardcore podcast catchup...
