New Planets

  • Planets Need Heavy-Metal
    Astronomers have previously estimated that around five percent of stars may have planets, but a survey by Berkeley planet finders has refined this classification. If a star is rich in metals, particularly iron and other heavy metals, then it stands a remarkable one-in-five chance of

  • Interview with Neville Woolf: Part II
    This is the second of a two-part interview with Neville Woolf, a Professor of Astronomy at the University of Arizona. Woolf is the principal investigator of one of the lead teams recently awarded a five-year grant by the NASA Astrobiology Institute (NAI) to conduct astrobiology-related

  • Ancient Planet Discovered
    Using the Hubble Space Telescope, astronomers have identified the oldest and most distant known planet orbiting two burned-out stars. Its sky location in the constellation Scorpius places the planet as the M4 globular cluster. The discovered world is also the only planet found to orbit

  • Rock, Scissors, Paper and Water
    A recent European conference discussed what a new class of planetary search candidates called 'waterworlds' might require: foremost after water itself, for life to originate elsewhere on a distant world depends on a rocky core and organic pulp.

  • Similar Solar System at 90 Light Years
    Astronomers have found the first sun-like star with a giant gas planet in an orbit similar to Jupiter's. At a distance of 90 light-years, the similar solar system to ours means that this gas giant could attract most of the dangerous impact debris.

  • Twins Combine Planetary Light
    Debuting the first discoveries from the world's largest optical telescope, researchers have used the Keck Interferometer to combine light from two telescopes. Astronomers can see the growing gap between a star and its planets as they begin to accrete.

  • Inference and Red Corn
    Mathematical astronomer, Simon Newcomb, describes the limits of life on Earth and endeavors to ask the right questions about what might be required to discover life elsewhere.

  • Celestial Birthing Grounds: Wild Places
    A University of Florida sky survey has doubled the number of planet forming disks in a cluster of young stars, and suggests that planets may pop up within the first 3 million years of a star's life.

  • Eureka, The New World
    Planet-finding scientist, Geoff Marcy, describes just how it feels to find a new world. The UC Berkeley researcher describes the challenges and thrills of modern sky searches.

  • Hot New Eclipsing World Discovered
    Planet finding scientists have logged more than a hundred discoveries of new 'worlds' since the middle 1990s, but only two probable candidates have been found from changes in the parent star's brightness. Akin to a distant eclipse, this method is called a transit search.

  • New Planet Found, Big Dog Constellation
    A new planet has been found orbitting a Sun-like star in the southern constellation, Canis Major. The planet is about twice the size of Jupiter, and orbits so close that its annual 'season' is over in just two and half days.

  • First Light on New Planet Finder
    Atop a Chilean mountain- in the driest place on Earth- a new telescope promises to seek out distant stars that harbor planets. 'First light' showed that a star's velocity can be detected with the astonishing accuracy equivalent to the speed of a pedestrian's walk (within

  • Poof! How to Evaporate a Planet
    Astronomers using NASA's Hubble Space Telescope have observed for the first time the atmosphere of a planet beyond our solar system evaporating into space.

  • 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.
