NASA Media Telecon to Announce Latest Kepler Discoveries, 26 Feb.

"NASA will host a news teleconference at 1 p.m. EST (18:00 UTC), Wednesday, Feb. 26, to announce new discoveries made by its planet-hunting mission, the Kepler Space Telescope."

Kepler Has Discovered 715 New Extrasolar Planets

"NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system. Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets, which are planets outside our solar system."

Looking For Other Earths

Looking for a Mirror, NY Times

"The challenges to photographing a mirror Earth are daunting, but not insurmountable. A small rocky planet is a dim mote of dust lost in the glare from a thermonuclear fireball we call a star. For every photon of planetary light that goes into making a picture, 10 billion stellar photons must first be filtered out; remarkably, researchers have already devised several ways to do this. All that the planet-hunters really need to find the mirror Earths is a big mirror, high above the Earth's blurring atmosphere -- a space telescope large enough to gather the faint light of Goldilocks worlds around a sizable sample of stars."
