I am happy to give public presentations at schools, museums, or to interest groups such as astronomy clubs, Boys & Girls clubs, Scouts, etc. that are local to the southern PA / Baltimore / DC area. Please contact me as early as possible if interested. My areas of specialty are:

"Eyes In The Sky: NASA's Ultraviolet and Optical Space Telescopes" -- Telescopes in space have enabled revolutionary science for nearly 40 years: from the International Ultraviolet Explorer (launched in 1978), the Hubble Space Telescope (launched in 1990), FUSE (launched in 1999), GALEX (launched in 2003), and Kepler (launched in 2009). We will take a look at past and current NASA space telescopes, the discoveries they made, and what future space telescope missions have in store for us.

"From Science Fiction To Science Fact: What We Know (And Don't Know) About Alien Planets" -- Artists have created exotic alien worlds for decades, but only in the last 20 years have we begun to learn about the properties of real planets beyond our solar system. I'll review some of the incredible discoveries we've made, show examples of extrasolar planets that are quite similar to their sci-fi counterparts, and highlight a few intriguing questions we still don't have answers to.

"Dancing With The Stars: Amazing Science From Stellar Binaries" -- Binary stars consist of a pair of stars that orbit one another. Their separations can be as far apart as the distance between the Sun and our nearest stellar neighbor, or so close together that their surfaces actually touch one another. By monitoring the "dance" of their orbits around one another, we can learn a great deal about both stars and any planets that may orbit them. I will share some of the incredible discoveries that binary stars have enabled, including "puffy" stars whose radii are larger than we expect for reasons that are still unknown, "heartbeat" stars who get so close to one another they literally "tug" at each others' heart strings, and "Tatooine" planets that live in these binary systems and have not one but two stars in their sky.
