The past decades have revealed that planets are incredibly common, and
incredibly diverse. The origins of planets and their compositions are
intimately linked to the chemical environments within which planets
assemble, i.e. to the chemistry of planet-forming disks. The arrival of
ALMA has provided observational access to disk chemistry, revealing
disk
snowlines, abundant organic molecules, and curious chemical gradients
and sub-structures across the planet and comet forming zones. The most
recent development is the execution of the ALMA Large Program MAPS
(Molecules with ALMA on Planet-forming Scales), which has enabled us to
zoom in on disk chemical structures at scales of 10-30 au. In parallel
to these observational developments, astrochemistry models and
laboratory experiments are providing new clues on what chemistry is
likely to occur in different disk environments. I will present
highlights from the MAPS program, as well as some recent laboratory
astrochemistry discoveries. I will discuss how these new observational
and laboratory data are affecting our understanding of the chemistry of
planet formation, the chemical habitability of mature planetary
systems,
and the history of our own Solar System.
