The goal of the project is to create a deep, multi-epoch, multi-colour digital survey of the entire southern sky. This will facilitate a broad range of exciting science, including discovering the oldest stars in the Galaxy, finding new dwarf galaxies in orbit around the Milky Way, and measuring the effects of Dark Energy on the Universe through nearby supernovae.</p>  <p class="pad10">On this site you can <a href="/about-skymapper/">read about SkyMapper</a> and its <a href="/surveys">surveys</a>, browse the latest <a href="/data-release/">data releases</a> and query <a href="/how-to-access/">images and catalogues</a> using simple forms or Virtual Observatory web services.
