A protoplanetary disc has formed around the young star HL Tau

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.
