On the outskirts of creation, unknown, unseen "structures" are tugging on our universe like cosmic magnets, a controversial new study says.

The presence of the extra-universal matter suggests that our universe is part of something bigger—a multiverse—and that whatever is out there is very different from the universe we know.

My dad sent me this rather cool picture of the Helix Nebula, often called the Eye of God.

Next sunday, the 10th, theres a 1° bunching of Mercury, Jupiter, Mars, and Beta Scorpii low above the east-southeast horizon. Something that won't be seen for another 45 years or such.

Anyone know a good dark spot in and around Boston that I can take the kids that will allow viewing of the low horizon? I'm having trouble finding good local spots.

THE MEANING OF PLANET: What is a planet? For years, astronomers have been debating that question, with the status of tiny Pluto hanging in the balance. Finally, an answer is in the offing. Today, the International Astronomical Union's Planet Definition Committee announced their proposal for a new, official definition of "planet." If the proposal is approved by a vote of IAU astronomers on August 24th, the number of planets in the Solar System would swell from nine to twelve. And, yes, Pluto would be among them.

Here's the full text of the draft decision.

So if it passes the Solar System will have twelve planets: Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto and Charon (a double planet) and 2003 UB313. Hopefully 2003 UB313 will get a better name pretty quickly.

My first thought was "Oooh solar system hijincks always have gaming potential." Yes I know, gaming ideas are always my first thought. Thats not true, but its hard to think sexy thoughts about new planets though if I think about it...oh yeah.

My second thought was this will turn out to be a good spring board for lots of stuff for the boy. Nothing like discussing orbital mechanics with a six year old. And I'm serious there. The boy is fascinated by astronomy and has been discussing Pluto and Neptune's orbit a bunch lately, this should be very interesting to him.

I'm looking for last minute birthday gifts for the boy and I come across this, which uses point and click technology to identify stars and planets and tells you how to find them. Expensive and in some ways takes out some of the fun of learning astronomy but still very very cool and I want one.
