The Pan-STARRS1 telescope recently completed its four year mission mapping the skies above Maui. Its dataset, scheduled for release in mid-2015 consists of a suite of surveys of the sky with varying depths and cadences. The largest of these (the 3pi Survey) will provide a vast legacy dataset containing accurate g,r,i,z,y photometry and seeing-limited imaging for three quarters of the sky while other, smaller surveys consist of deeper/more frequent observations of specific areas of sky. The most
relevant of these to the UK community is the Medium Deep Survey which covers ten 7 sq.deg. fields each of which have ~500-800 observations per filter over four years. Thus these areas, specifically chosen to match legacy cosmological datasets, provide the ideal locations for identifying supernovae and for using stacked observations to investigate cosmological structure.

This is the largest optical legacy survey to date and offers not only a huge improvement over the optical plate imaging still relied on for much of the sky and with double the area of SDSS with better red-sensitivity but marks the beginning of the era of wide-field time domain astronomy with up to 12 epochs per filter. It provides a stepping stone towards the surveys to be undertaken by LSST.

We will present an outline of the data products available and their use to the UK community as well as presenting science highlights for UK-based Pan-STARRS institutions and beyond. These range from sub-stellar objects identified by trigonometric parallaxes to distant super-luminous supernovae. We will also provide a short workshop detailing how the data products can be accessed and an overview of possible synergies between Pan-STARRS1 and future surveys.
