"About 10 years ago, I started taking improv comedy classes when I lived back in Atlanta. It really teaches you how to go with the flow, to be present in a situation, to be ready for things to go wrong, and to be able to jump in and save a conversation or help somebody who is struggling to find the right words. These are things we do in our everyday lives that we can also do on stage, and I love that aspect of it. "I started using the tools of comedy to rewrite popular songs – such as from the musical Hamilton – to be about space. I love making people laugh and smile and think there’s something really special about finding things funny or amusing in a respectful way. It is a different level of connection than, ‘Oh, that's interesting.’ It ignites a different emotional response in you, and I think there’s a place for that in science communication as well. "Often in popular culture, there’s a bit of a stigma around people who enjoy learning about space and science; that it’s only for nerds. But if you insert it into a genre that you wouldn't normally find it in, like music or comedy, then suddenly you’re connecting with people on a different level. They might not go out and read a textbook, but they might come away from a song or a comedy show thinking, ‘Huh, I thought I was just going to this event for entertainment, but I actually learned something.’ That’s cool! It’s like you’re seasoning it or putting a little sugar in it. "Something improv comedy taught me is: When you start to let go and not take yourself too seriously and embrace the spontaneity of a situation, that’s really freeing, and people respond well to that."

A supermoon rises behind the Washington Monument, Sunday, June 23, 2013, in Washington. This year the Supermoon is up to 13.5% larger and 30% brighter than a typical Full Moon is. This is a result of the Moon reaching its perigee - the closest that it gets to the Earth during the course of its orbit. During perigee on 23 June the Moon was about 221,824 miles away, as compared to the 252,581 miles away that it is at its furthest distance from the Earth (apogee). Photo Credit: (NASA/Bill Ingalls)
