Is NASA going to launch a telescope that can detect earth size planets?
They did, called the Kepler Mission. It uses a NASA space telescope designed to discover Earth-like planets orbiting other stars. Orbiting the sun for at least 3.5 years, Kepler will continuously monitor the brightness of over 100,000 stars in a fixed field of view. The data collected will be analyzed to detect periodic fluctuations that indicate the presence of transiting exoplanets. So it isn’t using the wobble of the stars, but the change in brightness due to orbiting planets. http://www.nasa.
