Today students continued working in their research groups. Research topics include pulsars/ supernova remnants, black holes, the Sun, the habitable zone of the Milky Way galaxy, gravitational lenses/ quasars, and dark matter. Student astrobiology presentations by Danya, Will, Caitlin, and Indy followed. After lunch Dr. Mercedes Lopez- Morales of the Carnegie Institute in Washington, presented a soon- to- be- published paper about substellar companions to white dwarfs. Students continued to finalize their research plans. The dedicated few played soccor in the rain (which was one of the reasons for my blurry pictures). Dr. Mel Blake gave a presentation about light pollution and we observed the International Space Station streak across the sky.
