I enjoy astronomy, always have. This is a new age for astronomy fans. The web, coupled with outrageously powerful modern instruments is truly opening the cosmos up to everybody with an Internet connection. I present:

Alien Art's Astronomy Links
A favorite of mine is the Current Solar Images Page at SDAC. This site shows current images of the Sun updated daily. Seriously, you can see images of the sun from the last day or so. Lately, with the upcoming maximum in the Sun Spot Cycle, interest with solar phenomenon is high. Don't get excited, the sun isn't doing anything it hasn't before, we just didn't have the same information back then. The images below are updated every day. Really they are.
Yonokoh soft x-ray image
You might think that the Sun doesn't change much. It shines every day pretty much the same. Well, a lot of action takes place there. It is a very dynamic pulsing entity. At left is the latest image of the Sun from the Yohkoh Soft X-ray telescope. This image shows what's going on in the Sun's atmosphere, where temperatures are much hotter than the surface. The surface is black (cooler) and particles in the atmosphere are heated so hot that they emit radiation in the X-ray band.
Extreme Ultraviolet
At left is the latest image from the Extreme ultraviolet Imaging Telescope imaging excited Iron atoms. Click on either image at left to go to the Solar Data Analysis Page at the Goddard Space Center. There, you will find additional current images of the Sun at different wavelengths, along with larger images. News just announced that huge rivers of plasma have been found beneath the Sun's surface.
