ESOcast SD show

Summary: ALMA has uncovered convincing evidence that three young planets are in orbit around the infant star HD 163296. Using a new planet-finding technique, astronomers have identified three discrete disturbances in the young star’s gas-filled disc: the strongest evidence yet that newly formed planets are in orbit there. These are considered the first planets discovered with ALMA.
