| This artist's concept shows the huge, scorching-hot "Einstein's planet," formally known as Kepler-76b, orbiting its host star, which has been tidally distorted into a slight football shape (exaggerated here for effect). The planet was detected when astronomers spotted brightness changes in the star induced by the planet due to relativistic effects. CREDIT: David A. Aguilar (CfA) |
Einstein's special relativity has proven more useful than ever, as scientists have now used it to discover an alien planet around another star.
The newfound world — nicknamed "Einstein's planet" by the astronomers who discovered it — is the latest of more than 800 planets known to exist beyond our solar system, and the first to be found through this method.
The planet, officially known as Kepler-76b, is 25 percent larger than Jupiter and weighs about twice as much, putting it in a class known as "hot Jupiters." The world orbits a star located about 2,000 light-years from Earth in the constellation Cygnus.
Note: I reproduced the text verbatim, but I think that General Theory - i.e., gravitational lensing - is probably how the planet was discovered, and it is not a new or unique method. RG
