SkyMapper's Southern Survey is led by the Research School of Astronomy and Astrophysics at the Australian National University, in collaboration with seven Australian universities and the Australian Astronomical Observatory. 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.

On this site you can read about SkyMapper and its surveys, browse the latest data releases and query images and catalogues using simple forms or Virtual Observatory web services. Before downloading or publishing data we ask that you review the policies section to familiarise yourself with the authorship and protected science policies. As part of SkyMapper's status as a National Facility, Australian astronomers will typically enjoy exclusive access to each data release for 12-18 months. International astonomers are welcome to use the data after such time, or collaborate with Australian colleagues. Please contact us for more information.

Upcoming ASVO Downtime | 24 Nov 2020

The SkyMapper node of the All-Sky Virtual Observatory will be offline from 5pm on 26 November (AEDT) for a period of up to 5 days. This is due to urgent maintenance on the file storage systems at the National Computational Infrastructure.

In particular, we anticipate the image cutout service (including postage stamps displayed in the Object Viewer) will be unavailable during that time. Cone search and catalogue queries may still work, but the full functionality of those services is not certain.

We apologise for any inconvenience.
