On the Road with David Levy

Longtime Sky &Telescope contributor David H. Levy is most famous for his co-discovery in 1993 of the Comet Shoemaker-Levy, which collided with Jupiter in 1994. But he began his comet search long before then, in December of 1965, and has discovered or co-discovered 22 comets since then. That only begins to describe his observing experience — he has also observed 77 eclipses, from total solar eclipses to penumbral lunar eclipses. As he blogged for S&T, he dispensed advice on how to observe and (even better) discover comets.

He also reported on another strong passion: astronomy outreach, covering several sky-watching events associated with 2009’s International Year of Astronomy, and other ongoing activities such as University of Arizona’s Astronomy Camp.

Coming Home

Sky & Telescope contributing editor David H. Levy heads back to his alma mater in Nova Scotia, Canada, to teach, remember, and reflect.

During the 2004 Geminid meteor shower, Alan Dyer caught a bright fireball with a tripod-mounted digital camera. He used a wide-field, 16-mm lens for a 1-minute exposure at f/2.8 with an ISO setting of 800. Expect to shoot a lot of frames before you get this lucky. Click image for larger view.
