The popular early-morning radio program “Overnight America,” hosted by Jon Grayson, which runs from 1 a.m. to 6 a.m. Eastern time, has recently expanded from five stations to 25. It originally aired on stations in St. Louis, Missouri; Minneapolis/St. Paul, Minnesota; Orlando, Florida; Roanoke, Virginia; and Pittsburgh, Pennsylvania.

Newly added markets include Memphis and Nashville, Tennessee; Detroit, Michigan; Tulsa, Oklahoma; Jackson, Mississippi; Denver and Grand Junction, Colorado; Worcester/Boston, Massachusetts; Phoenix, Arizona; Anchorage, Alaska; and Los Angeles, California.

Astronomy magazine has been a proud partner of this program since April 2008. At the beginning of each month, Grayson chats with Senior Editor Michael E. Bakich for two segments. The first addresses what’s up in the sky and answers basic questions such as, “Which bright planets are easy to spot?” “Will there be any meteor showers or eclipses?” and “What’s the right telescope for me?”

The second segment focuses more on the science end of astronomy. Anything currently in the news — and there’s always something — is fair game. Grayson finishes by asking Bakich to talk about what’s in the current issue of Astronomy magazine.

“Jon is the greatest interviewer I’ve worked with,” says Bakich. “He really knows what he’s talking about when we chat astronomy. And he’s genuinely interested in the subject, which really comes across to his many listeners.”

If you live within broadcast range of a station that carries “Overnight America,” tune in. You’ll learn all about astronomy and a lot more.
