SCOPE

Today you are going to contribute to real scientific research, classifying stars. You are going to look at the spectra generated by stars, and figure out their spectral type (what the star looks like and what it is made out of). Each star will be classified by 10 people (you may be one of them). The results of all 10 people will be averaged, and the star can be classified.

You will need to create an account, and classify 6 stars today. Click here to register.
