The Allen Telescope Array, planned for completion in the next few years, promises a robust and novel use of off-the-shelf radio dishes. Deployed in northern California, this dish array is one intriguing technology that Dr. Jilll Tarter, director of SETI Research at the SETI Institute, describes when she outlines her version of: what is 'the best job in the world'?

Dave DeBoer, Project Engineer for the Allen Telescope Array, discusses what the unique telescope will offer. The development of the Allen Telescope Array is marked by many innovations crafted with the express purpose of building a world-class state-of-the-art astronomical facility at a fraction of the price of existing radio telescopes.

Few modern scientific adventures can rival what is currently the task of those discovering new planets. While most of the hundred or so new worlds found so far have been found using the planet's inferred influence on its parent star's gravitational wobble, a few have been discovered as the planet eclipses its own star. Called the transit method, this technique has tallied at least one candidate which can be observed with all manners of small and large telescopes, ranging from amateur reflectors to the orbitting Hubble Space Telescope.

One simplified view of what serves as a SETI criterion for artificiality is this: Narrow-band signals in the radio, and brief photon bursts in the optical. Finding a laser-pulse sent towards earth is part of an ongoing investigation at the Lick Observatory, University of California Santa Cruz, to search for optical flashes.

Some planets are magnetically active or large enough to pump out significant radio signals. Whether this proves to be enough for detection of other worlds depends on the size of the detection array.

A sky survey by Anglo-Australian astronomers has put forward a new calculation for the number of stars in the visible universe. Their estimate is larger than the number of sand grains on Earth.

Most passengers on a Boeing-747 spend their flight looking down at the farms, mountains and roads. A specially-equipped infrared telescope is now slated to take a similar flight, but spend its first-class trip looking to the skies.

When the Allen Telescope Array comes online in a few years, its thousand-fold better radio search capabilities would soon exhaust previously cataloged stars with potentially habitable planets. So Margaret Turnbull and Jill Tarter have a new list, called HabCat: A Catalog of Nearby Habitable Stellar Systems.
