The birth of stars and planets: new views from ALMA and JWST

Thousands of planets have been discovered around stars other than our Sun. But how and where are these exo-planets born, and why are they so different from those in our own solar system? Which ingredients are available to build them? Thanks to powerful new telescopes, astronomers can now zoom in to planetary construction sites and study their composition. Water and a surprisingly rich variety of organic materials are found near forming stars, including simple sugars, ethers and alcohols. This lecture will present an overview of recent results from ALMA and JWST on protostars and protoplanetary disks, with implications for the material (e.g., C/O) out of which planets are built.
