Using the SPHERE instrument, we have recently discovered a planetary mass companion in the gap of the transition disk around PDS 70 using the SPHERE instrument. PDS70 b is unambiguosly detected throughout the entire near-infrared spectral range and at multiple epochs, implying the presence of a ~5-10 Mjup object on a 22 au wide, disk coplanar orbit. I will present new ALMA band 7 observations of the dust continuum and CO emission and discuss the disk morphology seen in the sub-millimetre regime in the context of PDS 70 b.
