From BBC news, http://www.bbc.com/news/science-environment-29932609# "The clearest ever image of planets forming around an infant star has been taken by the Alma radio telescope. In a vast disc of dust and gas, dark rings are clearly visible: gaps in the cloud, swept clear by brand new planets in orbit. The sun-like star at the centre, HL Tau, is less than a million years old and is 450 light years from Earth in the constellation Taurus. The image was made possible by Alma's new high-resolution capabilities. Because the process of planet formation takes place in the midst of such a huge dust cloud, it can't be observed using visible light." Is science cool or what!
