First, a reminder that the MIDTERM IS NEXT THURSDAY. This means that there is NO HOMEWORK due next week. We will review for the midterm in class on Tuesday, so come prepared with any lingering questions that you want answered before the exam.
Also, check out some new astronomy results that were announced at the Signposts of Planets Conference at NASA Goddard (the conference I’m at right now) yesterday.
