We introduce LEGUS, a Hubble Space Telescope program which will provide
a critical missing piece in our efforts to solve the star formation
puzzle: a robust characterization of the links between star formation on
two fundamental scales, those of individual young stars, stellar
clusters and associations over parsec scales, and of galaxy disks over
kiloparsec scales. As a 154-orbit Treasury survey, LEGUS has begun
obtaining NUV,U,B,V,I imaging of 50 star-forming galaxies, at distances
of 4-12 Mpc. The dataset is guaranteed to have exceptional legacy value,
as the targets have been carefully selected to uniformly sample a full
range of global galaxy properties, as well as have the largest suites of
multi-wavelength ancillary data available. The high-resolution HST NUV
and U imaging are key for deriving accurate recent (<50 Myr) star
formation histories from resolved massive stars, along with the ages and
masses for complete samples of star clusters and associations in each
galaxy. We present an overview of the sample, the observations, and
provide a first look at the science that the LEGUS team is pursuing. A
companion poster presents the status of the program, and a more detailed
description of the extensive data products being developed which will
seed community science, and provide a foundation for studies of star
formation with ALMA and JWST.
