I'm an astrophysicist working at the Harvard-Smithsonian Center for Astrophysics as part of the Chandra X-Ray Center, which operates the Chandra X-ray Observatory spacecraft. You can contact me at firstname.lastname@example.org or email@example.com.
In addition to my day job I carry out research into the history of the space program and write an email-distributed newsletter, Jonathan's Space Report . From 1993 to 2010 I wrote a monthly column for Sky and Telescope Magazine which I still recommend as a great source of astronomy info. I've also appeared on TV around the world pontificating on the latest goings-on in space and have now ventured into the podcastosphere. You can see me chat with Neil Tyson at the WGBH Forum, and some TV here, and on some CfA items
