  • Lunacy: Finding New Moons?
    The technology required to find a planet outside our solar system boggles the imagination: the star itself is typically a billion times brighter than the planet, which gets lost in its host's glare. But with more than one hundred such planets now logged, can a

  • Automated Telescope Grids, Instant Messages
    Connecting robotic telescopes together on an automated network may offer astronomers instant alerts of stellar events. Examples like new planet detection, supernovae, or near-Earth asteroids are just a few of the options that may be coming to a nearby mobile phone.

  • Dyson’s Long Shot
    Renowned physicist Freeman Dyson, famous for his designs of grand energy collectors called Dyson's Sphere, has put down a public bet: life will first be discovered elsewhere not on a planet or moon, but someplace other than what we could recognize as terrestrial turf.

  • Cause for Optimism: Part III
    The NASA exobiology branch sponsored a public forum in Palo Alto, CA, on Tuesday, August 26, 2003, entitled, "The Drake Equation Revisited." The forum addressed the questions of estimating the probabilities for finding intelligent life in the universe. This is the third in the series

  • Habitability: Betting on 37 Gem
    What star meets the current best guesses for habitability? This fascinating question is part of an ongoing research survey, in preparation for NASA's Terrestrial Planet Finder mission. The answer, according to the largest such classification so far attempted, is the 37th brightest star in

  • BOINC At Home
    The most powerful computing network ever assembled is about to enter a new design phase. Drawing on the vast unused idle times of more than four and half million home computers, SETI@home gets 15 TeraFLOPs and costs $500K so far, compared to a typical

  • Discovering New Worlds
    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

  • Brown Dwarf Detectives
    Studying the chemical fingerprints, or spectra, from fifty brown dwarf stars has revealed not only features of why such failed stars (about the size of Jupiter) are hard to find, but also some guesses as to why they may outnumber the visible stars in our

  • Infrared Telescope Powers Up
    The Infrared Space Telescope has snapped it first image and transmitted the 'aliveness' test back to Earth. This sun-circling observatory will help astronomers probe the primordial universe, since most of the remnants of that epoch are now more available in infrared.

  • Alpha and Omega: Part II
    How did the universe begin and how will it end? And perhaps, more importantly, how can we know? Science magazine writer, Charles Seife, has taken up this compelling question in his new book, Alpha and Omega. He discusses the findings of cosmologists in Part II
