New Laser Technology Could Find First Earth-like Planets
Earth-like planet
CfA astronomers are developing a new device that may be the first to spot Earth-like planets, like the hypothetical world with two moons shown in this artist's concept. The "astro-comb" uses a laser to provide an ultrasensitive way of measuring a distant star's wobbling motion, which is induced by an orbiting planet.
