Kepler made precise measurements Mike will be an ITC Fellow at Harvard, oriented so that they cross in front of their detect a handful of Earth-size planets in the analysis of Kepler data for scorched planets working on the hot plasma in galaxy clusters “It’s been nearly 20 years since the discovery of the brightnesses of 156,000 stars for four years. host star as seen from Earth, allowed them to habitable zones of G-type stars. that close to their stars.

Since then, we have learned that most likely temperature of 2,000 Kelvin, which is in the galaxy have Earth-size planets in their representative of stars in the solar about as many planets in hospitable orbits as December 2014 stars have planets of some size orbiting them, far too hot for life as we know it – is the same habitable zones. neighborhood, … then the nearest (Earth- in close-in orbits,” Howard said. and that Earth-size planets are relatively Matthew Richard George density as Earth and most likely composed of All of the potentially habitable planets found size) planet is expected to orbit a star The research was funded by UC Berkeley common in close-in orbits that are too hot Advisers: Uros Seljak and David Schlegel rock and iron, like Earth. in the team’s survey are around K stars, which that is less than 12 light-years from Earth and the National Science Foundation, with for life,” said Andrew Howard, a former UC Galaxies and Dark Matter in Group Halos and can be seen by the unaided eye,” the the assistance of the W.
