The pull of gravity on a distant star can now be measured more accurately, shedding light on other worlds, say astronomers. The method makes it possible to study even the faintest of stars. "Our technique can tell you how big and bright is the star, and if a planet around it is the right size and temperature to have water oceans, and maybe life," said Prof Jaymie Matthews.
