Pan-STARRS is a distributed aperture approach to wide-field optical
and near-IR imaging. It employs 1.8m telescopes with a very large
field of view with 1.4 Gpixel CCD detectors. The first telescope,
PS1, has been fully operational for over a year, and has completed one
scan of the sky in the g, r, i, z and y pass-bands. In this talk
I will briefly describe the system, the design of the surveys, and
the performance that has been obtained to date with PS1. I
will then show some of the early science results that have been obtained.
These include full maps of the sky North of declination -30 at one-micron
mapping of galactic dust from stellar reddening; microlensing in M31
detection of hundreds of supernovae for dark-energy and supernova physics
studies, along with large samples of variability selected AGN and QSOs
galaxy counts; detection of clusters of galaxies, both from optical
photometry alone and from optical confirmation of low-significance
X-ray detections and, last, but not least, detection of large numbers
of near earth objects, including some of the most hazardous objects
currently known. I will conclude with forecasts for the depth of the
surveys that will be generated in the next few years.
