5 things learned at the symposium

When I made my way to the symposium I made it there just in time to catch one poster because all the others were being taken down. However it was John's so I learned a lot
1. Over the summer John worked with a professor studying Differential Photometry ( Studying light from different asteroids.)
2. John told me he learned that you can view asteroids with astronomy not just the stars.
3. Also you can see changes in the universe through studying the light things give off
4. When studying the asteroids 10 Hygiea and 9 Metis, they used a CCD camera in Australia to make their observations.( I assume they used it through online usage)
5. The rotation periods of 10 Hygiea and 9 Metis were 26.9 hours and 5.6 hours respectively, they discovered this by using a method called Fourier transforms.
They also observed signal noise, which they measure through the amount of light that the asteroid gives off per rotation.
Also I got a nice little picture of our wonderful classmate John
