Four giant planets around young star discovered

Scientists have identified a young star with four Jupiter and Saturn-sized planets orbiting it, the first time that so many massive worlds have been detected in such a system. The star, CI Tau, is located about 500 light years away in a highly-productive stellar 'nursery' region of the galaxy, said researchers from the University of Cambridge in the UK.
