We image with unprecedented spatial resolution and sensitivity disk featuresthat could be potential signs of planet-disk interaction. Two companioncandidates have been claimed in the disk around the young Herbig Ae/Be starHD100546. Thus, this object serves as an excellent target for our investigationof the natal environment of giant planets. We exploit the power of extremeadaptive optics operating in conjunction with the new high-contrast imagerSPHERE to image HD100546 in scattered light. We obtain the first polarizedlight observations of this source in the visible (with resolution as fine as 2AU) and new H and K band total intensity images that we analyze with thePynpoint package. The disk shows a complex azimuthal morphology, where multiplescattering of photons most likely plays an important role. High brightnesscontrasts and arm-like structures are ubiquitous in the disk. A double-wingstructure (partly due to ADI processing) resembles a morphology newly observedin inclined disks. Given the cavity size in the visible (11 AU), the COemission associated to the planet candidate 'c' might arise from within thecircumstellar disk. We find an extended emission in the K band at the expectedlocation of 'b'. The surrounding large-scale region is the brightest inscattered light. There is no sign of any disk gap associated to 'b'.
