September 2010: The next great space telescope takes shape
This month's issue of Astronomy magazine takes an in-depth look at the James Webb Space Telescope, reveals the background and inner workings of the Galaxy Zoo project, announces the 35 selections for the magazine's first annual Star Products, and more.

|WAUKESHA, Wis. — It's hard to imagine any scientific instrument more successful than the Hubble Space Telescope, with its beautiful photos, legions of fans, and underdog-turned-hero success story, but then again NASA's in the business of meeting difficult expectations. Its latest effort will begin in late 2014 or early 2015: the James Webb Space Telescope.|
In "The next great space telescope takes shape," Francis Reddy, a senior science writer at NASA's Goddard Space Flight Center, explains the need for a next generation space telescope (Webb's original name) and exactly what it'll look at. "Webb's mission is as simple as its design is state of the art: to show us what Hubble cannot," Reddy writes.
Designed to see in infrared light, Webb will go farther than Hubble, which mostly observes visible light. Hubble's successor will study early galaxies, exploding stars, and the dusty regions of stellar and planetary birth, among other objects. "These represent only a few of the scientific questions that the James Webb Space Telescope will address," writes Reddy. The future, unlike Webb's targets, looks bright.
Pick up the September issue of Astronomy, on newsstands August 3, to learn the history behind the James Webb Space Telescope and what astronomers expect of its mission.
"Welcome to the Galaxy Zoo"
Professional astronomers aren't the only ones making contributions to the science of astronomy, as University of Alabama astronomer William Keel makes clear in "Welcome to the Galaxy Zoo." The Internet-based Galaxy Zoo, with its lively community of "Zooites" and benevolent "Zookeepers," makes it possible for almost anyone to begin classifying galaxy shapes within minutes of logging on. With 11 scientific papers and a mysterious object (Hanny's Voorwerp, a cloud of gas near galaxy IC2497) to its credit, Galaxy Zoo is quickly becoming an astronomical powerhouse.
"Astronomy's first annual Star Products"
Phil Harrington and the rest of Astronomy's staff worked hard to decide which of the latest telescopes, binoculars, and other astronomy gear to include in this list of the 35 best. You can't go wrong with any one of them, but why stop at just one?
