  • The Velocity of Planets
    Researchers have developed a new technique to detect small, extrasolar planets that are more Earth-like than the majority of planets discovered thus far. They call it the "astro-comb", and it could help astrobiologists in the search for distant, habitable worlds.

  • Exoplanets Exposed to the Core
    Astronomers have determined that giant exoplanets orbiting close to their stars could lose so much of their mass that only their cores remain. The smallest exoplanet discovered so far, which is less than twice the size of Earth, may be an example of this phenomenon.

  • Double Discovery: Super-Earth and Ocean World
    Researchers have made two amazing discoveries regarding the Gliese 581 system. The star is orbited by the lightest exoplanet ever found, less than twice the mass of the Earth. One of the other planets in this system, a super-Earth, orbits within the star´s
