Two planets discovered
WASHINGTON: In a solar system thousands of light years away, a star about half the size of our sun is being orbited by two planets that seem like smaller versions of Jupiter and Saturn, astronomers report.
The simultaneous discovery of two planets is rare and this was the first time researchers had the opportunity to do so using a technique called gravitational microlensing.
“You could call it luck, but I think it might just mean that these systems are common throughout our galaxy,” said Scott Gaudi of Ohio State University, lead author of the report in Friday’s issue of the journal Science.
The star and its planets were observed when they passed in front of a more distant star in 2006. A lensing effect magnified the light of the distant star 500 times, the researchers explained. — AP
