Journal ArticleDOI
Extrasolar planets: Water world larger than Earth.
TL;DR: The hunt for Earth-like worlds has taken a major step forward with the discovery of a planet only 2.7 times larger than Earth whose mass and size are just as theorists would expect for a water-rich super-Earth.
Journal ArticleDOI
HAT-P-7: A Retrograde or Polar Orbit, and a Third Body
Joshua N. Winn,John Asher Johnson,Simon Albrecht,Andrew W. Howard,Geoffrey W. Marcy,Ian J. M. Crossfield,Matthew J. Holman +6 more
TL;DR: In this article, the authors show that the exoplanet HAT-P-7b has an extremely tilted orbit, with a true angle of at least 86 degrees with respect to its parent star's equatorial plane, and a strong possibility of retrograde motion.
Journal ArticleDOI
Area Coverage of Expanding E.T. Signals in the Galaxy: SETI and Drake’s N
TL;DR: In this article, the authors developed a simple model of the galaxy that includes both the birthrate and detectable lifetime of civilizations to compute the possibility of a SETI detection at the Earth.
Journal ArticleDOI

TL;DR: The radial velocity-discovered exoplanet HD 97658b was recently announced to transit, with a derived planetary radius of 2.93 \pm 0.28 R_{Earth}, corresponding to the reported 3\sigma lower limit.
