We've decided to introduce a new, intermittent series to the Chandra blog. From time to time, we'll dig into our vast archive of questions submitted by the public and post the answers written by experts at the Chandra X-ray Center. Some of these will be Chandra-specific or at least X-ray astronomy related. Others, well, they'll be somewhat random. Enjoy.
