Weather seems to be a common feature of planets with atmosphers, but the concept of rain on a star is a bit odd. If you have a star with a cool enough atmosphere - a brown drawf for example - you could have metalic condensation.
A cold front will come through this afternoon with temperatures falling to 1520. Expect strong iron rain and dangerous lightning.

The Sloan Digital Sky Survey will create the largest map in history by carefully taking very high resolution images of about a quarter of the sky. It will represent an incredibly rich tool for astronomy, astrophysics and cosmology. Technically it will cover 10,000 square degrees of the Northern sky to a 0.5 arc second resolution in five optical bands.
The wonderful thing is that the data, after a year with the SDSS consortium members, is published. By 2007 the entire survey will be generally available. Currently the first year's data is available.
The project has a website that comes with descriptions, papers, tools and projects for kids. This could be a serious tool for amateur astrophysics (we have amateur astronomy - why not astrophysics)
The tools page will get you going ... it seems wrong to look at anything else this morning. This link goes into my bookmark list (now up to 11).
