  • Planet Found Orbiting Red Giant
    A new planet has been discovered in the southern constellation, Canis Major (The Great Dog). The Jupiter-like planet orbits a Red Giant star--more than 400 light-years away and the second most distant planetary system yet.

  • Telescopes for Stardust
    As they reach Earth at faster than bullet speeds, extrasolar meteors hint at distant planet formation. Radar telecopes could trace dust grains back to neighboring solar systems, detailing their journey as grand detective stories for astronomers.

  • What Does ET Look Like from 40 Light Years Away?
    The Terrestrial Planet Finder (TPF) mission will have the technology to look for signs of life in the light reflected or emitted by planets orbiting nearby stars. But nobody knows exactly what signals life would emit. Clues from studies of Earth's early atmosphere are guiding

  • New World of Iron Rain
    Discover the remarkable new planet that has a year that lasts a terrestrial day, and rains down not water, but iron. The discovery is made possible by a planetary detection method--called a transit search--where the parent star dims as the orbitting planets pass across

  • Water Worlds
    Italian astronomers report on a method for water detection on extrasolar planets and cometary clouds, and their shortlist of candidates with promising initial findings from the 32-meter Medicina radio telescope.

  • Gravity’s Telescope
    Using a technique known as "gravitational microlensing", astronomers hope to find planets in Earth-like orbits around stars halfway across the galaxy.

  • Anybody Out There? Part II
    Famed neurologist Oliver Sacks is the author of many books, including "The Man Who Mistook His Wife for a Hat" and "Uncle Tungsten". In this second of a two-part essay on astrobiology, Dr. Sacks muses on the possibility of life on other worlds.

  • Aliens Depend on Time to Grow Brains
    To understand how intelligence develops, we have only one example to study: the development of human intelligence on Earth. Since intelligent life took a long time to develop on Earth, some believe it will take just as long on other worlds.

  • Pop-Up Planets
    New calculations estimate giant planet formation may take only centuries instead of tens of millions of years.

  • Concerted Evolution
    The rapid advances in genetic sequencing have allowed comparisons previously unavailable to those scientists who try to understand how such a complicated structure as DNA might have evolved. But communicating an entire organism compactly in code may require a more ancient art: the music

  • The Sun Also Rises Twice
    The startling effect of twin shadows and dual sunrises would make for double-vision on the first planet found orbiting a closely-coupled binary star system.
