Revolutionary ALMA image reveals planetary genesis
ALMA, the Atacama Large Millimeter/submillimeter Array, revealed remarkable details of a solar system that is forming. The images of HL Tauri were the sharpest ever made at submillimetre wavelengths. They show how forming planets are vacuuming up dust and gas in a protoplanetary disc.
