Einstein's work leads to alien planet 2,000 light-years from Earth being discovered

One of Albert Einstein's stranger ideas has led to the identification of a new planet twice as heavy as Jupiter, orbiting a star some 2,000 light-years from Earth.

‘This is the first time that this aspect of Einstein's theory of relativity has been used to discover a planet,’ said Tsevi Mazeh, of Tel Aviv University.

The discovery made use of the beaming effect which occurs when light from the parent star brightens as its planet tugs closer to Earth, and dims as the planet pulls it away.
