If we can see a star oscillating towards and away from us, we can infer that an unseen planet is tugging on its parent star as it orbits. We will learn just how hard it is to precisely measure the speeds of stars to the precision of 9 cm/s (0.2 mph!) necessary for finding these Earth-like planets. Next-generation ... more
