The transformational imaging capabilities offered by the Atacama Large Millimeter Array (ALMA) and the
Karl Jansky Very Large Array (VLA), as well as high-contrast near-infrared cameras, are opening an
unprecedented window on the planet formation region in nearby young stellar objects. This enables us to
investigate how gas-rich disks around young stars evolve and form planetary systems. This is a key step to
understand the origins of our Solar System and the puzzling diversity in the demographics of known
exoplanetary systems. I will summarize the current understanding of the planet formation process and present
the most recent results from observations that spatially resolve the planet formation region in nearby disks.
I will discuss the constraints on the initial conditions for planet formation, such as the radial distribution of the
circumstellar material and the properties of the circumstellar dust, which inform about the location and time
scale for the formation of planets. I will then present ALMA, VLA, and CARMA observations that reveal spiral
structures and asymmetries in the disk structure possibly caused by the interaction with planetary systems in
the act of forming. I will conclude by presenting future plans that combine the ALMA capabilities with those of
present and future high-contrast near-infrared cameras to study the formation and evolution of
planetary systems on spatial scales of a few AUs.
