EMU is a wide-field radio continuum survey planned for the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. Beginning in 2013 EMU will map the entire Southern Sky, extending as far North as +30 degrees declination, down to 10 microJy rms covering 1100-1400 MHz. EMU will cover roughly the same fraction (75%) of the sky as NVSS , but will be 45 times more sensitive, and will have an angular resolution (10 arcsec) five times better. There will be approximately 70 million radio sources detected and catalogued, including star forming galaxies out to z=1, powerful starbursts to z>1, and AGNs to the edge of the Universe. EMU will overlap with upcoming optical and infrared surveys (i.e. SkyMapper, WISE ) making EMU a resource for all astronomers. EMU is an open collaboration of 180 members from 14 countries. This presentation will describe the key science drivers of the survey, outline the data release process, highlight some of the science currently being completed to help EMU achieve its science goals, and provide an update on current progress.
