I just learned about a really fun and neat way for science-oriented kids to get involved in doing some REAL science. There is an amazing project to categorize galaxies called Galaxy Zoo 2, and they need help.
There have been thousands of faraway galaxies observed by robotic telescopes as part of the Sloan Digital Sky Survey. As it turns out, human beings are much better at looking at these images, and grouping them into categories, than any software that has so far been written.
It is pretty easy to signup for an account, and there is an easy to follow tutorial that even a grownup could understand. Next thing you know, you are working with of a team of deep space astronomers helping unlock secrets of the universe. Cool!
Anyhow, go check it out, and let your inner space explorer run wild. From looking at the message boards, there are a lot of people very into this, and I can see why.
