Associate Editor Daniel Pendick answers the “Ask Astro” question: How do X-ray telescopes work? 

Columnist and Contributing Editor Phil Harrington recommends a few more binocular targets in and around Coma Berenices in All around Coma Berenices.

And for those of you who enjoyed our new department “Astro Confidential,” we’ve included a few thoughts from Lisa Randall, David Helfand, Matt Mountain, and Ann Hornschemeier that didn’t fit in the magazine in Astro Confidential: Extending the conversations.

Of course, we’ve also posted “Bob Berman’s Strange Universe,” “Glenn Chaple’s Observing Basics,” “Phil Harrington’s Binocular Universe,” and “Stephen James O’Meara’s Secret Sky” columns for the April issue, in addition to “The Sky this Month” and “Ask Astro.”
