Today we did some interesting things. First the group listened to Professor Hartman discussing everything gamma ray. He explained that strong magnetic fields supply the power to generate gamma rays. I also learned that there are various sources for gamma rays. An interesting act I learned is that gamma rays are full of energy that if there was a mirror, the gamma ray would not be reflected, but it will penetrate the mirror and be absorbed. Today we also classified galaxies using the galaxy zoo. We are participating in a scientific study. We get to add to the database! It's pretty awesome!!! Can't wait to continue tomorrow!!!!'
