I’m snatching moments to write this from Chile, sitting on the floor of the airport, or bouncing up winding mountain roads in a van. I’m here as an Astronomy in Chile Educator Ambassador, with eight other ambassadors.

On February 11 of this year, when scientists announced that they had detected gravitational waves, I was among the thousands of people who were so excited we couldn’t sit still. This news was literally Earth-shaking! Gravitational waves are ripples in space-time, and they’re created by events like the collision of massive objects, such as black holes. So of course, being an astronomy educator, I took the first opportunity to talk about this news with visitors at the Museum. The day after the announcement, I set up our black holes Discovery Station, which uses a rubber sheet to demonstrate how space-time gets warped by massive objects. I created my own “gravitational waves” by tapping on the rubber sheet to make it vibrate, like ripples on a pond.

One of the many threads in our Explore the Universe gallery is the changing role of women in astronomy over the past two centuries. In the present gallery, opened in September 2001, we examine how the role of women as astronomers has changed over time from assisting family members to leaders of research teams.

It’s a tall order to sum up the past year at the National Air and Space Museum in a simple list. We’ve hosted astronauts and record breakers, we’ve moved and conserved dozens of artifacts as we transformed the Boeing Milestones of Flight Hall (and discovered some incredible things in the process), and held programs that illuminated the impact of aviation and spaceflight on our everyday lives. Where would I even start? I propose a compromise: I’ll summarize ten of my favorite events of this past year, then I’m relying on you to suggest yours. Did you have an experience at the Museum this past year that should be on our list? We’re asking you to share your favorite Air and Space moments in the comments.

One of the most common questions we get at the Phoebe Waterman Haas Public Observatory is about what kind of telescope to buy, whether for a gift or for personal use. In the height of the holiday shopping, we’re here to help answer that question.
