  • Solar System Snapshot
    Astronomers have captured the first infrared pictures of an entire solar system. So far, only three planets have been spotted - and they orbit a star that is only fifty percent larger than our sun.

  • Seeing a Distant Planet
    Astronomers have captured the first visible-light photograph of an extrasolar planet. The planet is about the size of Jupiter, and scientists believe that the system in which it resides could harbor more worlds.

  • Two Belts Cinch System
    Astronomers have discovered two asteroid belts and an icy outer ring around a nearby star. Scientists believe that the system might resemble our own solar system at the time of life's origin on Earth.

  • Cutting Life Short
    Imagine a solar system where a life-bearing planet is slowly pulled in closer to its star. If life could survive the ensuing climate change, it would provide a clear example of the Gaia hypothesis in action.

  • Get Them While They’re Hot
    Astronomers have determined that young, rocky planets stay hot longer than previously believed. The heat generated by these planets could make them easier to spot around distant stars.

  • Patterns in the Dust
    Astronomers may have discovered a new method for detecting planets as small as Mars orbiting distant stars. The method would open a new avenue in the search for habitable planets in the universe.

  • The Little Bang
    New research shows that a distant exploding star could have triggered the formation of our solar system. The study is helping astrobiologists understand the conditions in which habitable planets might form.

  • When Worlds Collide
    Astronomers have discovered that two terrestrial planets orbiting a distant star have recently suffered a violent collision. The new observation is unlike anything seen before, and sheds light on how interactions between planets can affect habitability.

  • Our Mixed-Up Solar System
    Chemical studies of the comet Wild 2 are challenging views about the history and evolution of the solar system. Such studies could yield important clues about the early formation of the planets.

  • Immigrant Sun
    New simulations show that stars like the sun can migrate great distances over time. The study may challenge the idea that galaxies have 'habitable zones' that are more suited for life than other areas.

  • Photo of an Extrasolar Planet
    Astronomers have released the first picture of a potential extrasolar planet that orbits a sun-like star. The newly-imaged planet may alter our understanding of planetary formation.
