Planet formation has been a rapidly growing research area in astrophysics. Over the last two years, our (1) high angular resolution observations at millimeter-centimeter wavelengths on a few selected protoplanetary disks (PPDs), and (2) the spatially unresolved surveys of the spectral energy distributions towards a large sample of PPDs, have depicted a new picture for the formation of Earth-like planets that have low water and carbon abundances, and the ice giants that are rich in water and organics. I will elaborate on our observations and how they lead us to our present hypothesis, which is largely in contrast to the common knowledge.
