Announcements

posted 6/14

Our first class meeting will be on Tuesday, September 5 at 9:55 am. Expect to get a reading assignment (that may include a short worked problem or two) about a week before the first class meeting.




Assignments

posted 6/14

An assignment to help you prepare for the first class meeting will be posted here about a week before classes start.

Do what you can to see the solar eclipse on August 21. It will be partial in Philadelphia but the path of totality stretches from Oregon to South Carolina.




Upcoming Events

Astro 16 students are members of the Department of Physics and Astronomy, and are encouraged to participate in department activities beyond the classroom. This includes attending regular talks – colloquia given by visiting scientists. Check the department colloquium schedule to see the list of talks (to be posted by the beginning of the semester). You'll find titles and descriptions of the talks, which are generally on Fridays at lunchtime.

You can also attend, and help out with, the monthly telescope open houses at the Peter van de Kamp Observatory, on the roof of the Science Center. This activity is optional, but fun. Bringing your friends is a good way to show them what all the astronomy excitement is about!
