Congratulations to the winners of the 2011 Nobel Prize in Physics.

Publicly available data from telescopes allowed Monash student Amelia Fraser-McKelvie to research and publish a paper about the missing mass of the universe. Her work is showcased in this episode of The Science Show on ABC's Radio National.

If you don't have your own telescope, you can use NASA's virtual one. The SkyView Virtual Observatory can generate images of any part of the sky at wavelengths in all regimes from Radio to Gamma-Ray.You don't have to be an astronomer to have a go - there is online help for the lay person.
