Abstract
The advent of ALMA has shown us that many proto-planetary disks have gaps and asymmetries. It is thought that these gaps may be caused by newly forming protoplanets but direct evidence has been missing. Here we present the first ever direct imaging observation of a multiple proto-planetary system. We use the narrow-field mode on the MUSE integral field unit to show that the star PDS 70 has two accreting proto-planets as shown by their Ha emission. The two planets appear to be in a 2-1 resonance which might explain the cavity observed in the disk around PDS 70. We also show that MUSE is an order of magnitude more efficient at this than SPHERE or MagAO and this is opening up an exciting future path for observations of forming exo-planets.
