Submission + - Previously Unseen Stage of Planet Formation Observed (

SchrodingerZ writes: "Seen from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile; scientists have detected a gas giant planet focusing material from a gas cloud towards a main star. The star, HD 142527, is a young 2 million years old, and is 450 light-years from Earth. The system has 'A disk of spinning dust and gas left over from its formation... and from this material, planets are being created'. The planetesimals, are drawing material from the dust cloud inward, effectively fueling the expansion of the parent star, currently twice the size of our own Sun. 'Theoretical simulations have predicted such bridges between outer and inner portions of disks surrounding stars, but none have been directly observed until now.' Simon Casassus, lead scientist at the University of Chile, stated that 'Currently, the only mechanism known to produce such gap-crossing dense molecular flows, with residual carbon monoxide gas more diffusely spread out inside the gap, is planetary formation.' While the planets currently are not visible, their presence is very noticeable, more examination of the dust cloud is needed to precisely pinpoint the planet(s)."
