Link -- Ask an Astrophysicist
I like this link, the "Ask an Astrophysicist" service of the Imagine the Universe! web site.
The web site specializes in cosmic-ray, gamma-ray, and X-ray astrophysics, and other satellite based astronomical observations. Their research subjects are often exotic, like black holes, quasars and dark matter.
