According to Charbonneau, the eight telescopes surveyed red dwarf stars looking for periodic faintness, a signal that a planet has crossed in front of its star, blocking out a small portion of the star's light...
Harvard researchers have discovered a "super-Earth" orbiting a red dwarf star 40 light-years from Earth with telescopes no larger than those used by amateur stargazers...
...team believes that the planet—named GJ1214b after the red dwarf star it orbits and 6.5 times the Earth's size—is primarily composed of water and ice but, at roughly 400 degrees Fahrenheit, is too hot to sustain life...
Harvard astronomy professor David Charbonneau and his colleagues discovered the super-Earth using the MEarth (pronounced "mirth") Project, an array of eight robotic telescopes that have monitored 2,000 red dwarf stars since...
...like stars - that is, large and hot - on the assumption that if you're looking for life, you should look in a place that is as similar to our solar system as possible. Charbonneau, however, focused on about 2,000 small, dim, red stars known as M-dwarfs, nearby Earth. M-dwarfs are much more numerous than Sun-like stars; of the 300 stars closest to Earth, says Charbonneau, 220 or so are M-dwarfs. They're also much cooler than Sun-like stars, so their habitable zones are close-in. A planet in the Goldilocks position around...
