The unprecedented imaging capabilities provided by ALMA and modern near-infrared high-contrast cameras have served as the foundation of a new and rapidly expanding field of research posed to unveil the origin of planetary systems. The outstanding discoveries obtained in the current decade have demonstrated that the outer regions of protoplanetary disks (>10 au) are much more interesting than expected. The direct imaging of newborn wide separation planets and the myriad of structures discovered in the dust and gas emission expose the complexity of the planet formation process. These unexpected findings urge for the construction of telescopes capable of imaging the terrestrial planet formation region (<10 au), where the vast majority of planets are expected to form. We argue that achieving sub-au imaging capabilities at wavelength between 1 mm and 1 cm should be a top priority for astronomy in the next decade. At these wavelengths the dust emission is optically thin, enabling us to peer through the densest disk regions and image planetary systems in formation. At the same time, we urge to intensify efforts aimed at developing sub-au resolution high-contrast planet detection techniques in the thermal infrared with the ELTs and infrared long-baseline interferometry. These capabilities are required to directly image newborn planets and measure their physical properties.< Leer menos
