The day Earth came to life
The September 2009 Astronomy magazine analyzes the puzzling existence of organic matter’s self-replicating system on Earth, reveals the winners of the 2009 Astroimaging Contest, explores the possible origins of our galaxy’s hyperfast stars, and more. It also debuts a new department, “Deep-sky Showcase,” which highlights great observing targets through photos and sketches.
Watch a video: Editor David J. Eicher previews the September issue.

Do you have a star party observing list? This summer, be sure to include Comet 22P/Kopff. The season’s top comet crosses the southern sky late at night and will show up best from a dark site. As it ambles across Aquarius the Water-bearer east of Jupiter, this periodic visitor to the inner solar system should glow around 9th magnitude.
Comet 22P/Kopff is now on its 16th return since German astronomer August Kopff discovered it in 1906. During the past century, this comet has been pretty dependable. Each time it approaches closest to the Sun, it spews out a similar amount of gas and dust. |

Each week, Astronomy magazine Senior Editor Michael Bakich, a master at explaining how to observe, posts a podcast about three objects or events you can see in the sky.
