Okay, not destroys, covers. Well, not really covers, but from here on Earth, sitting inside the shadow of the Moon, that's what it sure looks like. These events are called eclipses, or more precisely, transits and occultations. They occur whenever one object passes in front of another from a 3rd perspective. They're beautiful and exciting, and deliver a tremendous amount of science as well.

It was the search for a theoretical planet beyond Uranus that turned up Neptune, and then again for Pluto. And even now there are some astronomers who think there's a more distant planet out there. Oh, and there are a bunch of pseudoscience cranks trying to freak people out about the end of the world. Don't worry, we'll make time for them too, but first let's start with some real science.

Let's learn about the constellations and other star formations, their history, their connection to the zodiac, and how to find some of them.

I was wondering about an idea for a series of podcasts about famous past and present astonomers / cosmologists and their contirbution.

Certainly one I would suggest would be Carl Sagan. ]]> Astronomy Cast bluegruntfuttock http://www.bautforum.com/astronomy-cast/95444-podcast-subject-suggestion.html
