Astronomers See ‘Youngest Planet’

An embryonic planet detected outside our Solar System could be less than 2,000 years old. The ball of dust and gas, which is in the process of turning into a Jupiter-like giant, was detected around the star HL Tau, by a UK team. Research leader Dr Jane Greaves said the planet’s growth may have been kickstarted when another young star passed the system 1,600 years ago
