ALMA imaging of the transitional disc DoAr 44

This ALMA image combines a view of the dust around the young star DoAr 44 (orange) with a view of the gaseous material (blue). The smaller hole in the inner gas is a telltale sign of the presence of a young planet clearing the disc.

The bar at the bottom of the image indicates the diameter of the orbit of Neptune in the Solar System (60 AU).
