The Story of Light: Surveying the Cosmos

**SOLD OUT** Sunday 4 June 2017, 2–3.30pm Powerhouse Museum Book Tickets

How do astronomers explore the Universe?

Astrophysicists use extremely sensitive telescopes and instruments to collect the light emitted by stars, gas and galaxies. The analysis of this data provides the information needed to unlock the mysteries of the Cosmos.

However, this is not an easy task. Over the last two decades large international collaborations have been formed with the aim to map the skies, catalogue celestial objects, extract their properties and perform statistical analyses. These large astronomical surveys are now providing major advances in our understanding of the Cosmos at all scales, from searching for planets around other stars to detecting gravitational waves.

Australia is at the forefront of these collaborations thanks to the unique instruments at the Anglo-Australian Telescope (AAT) and the development of radio-interferometers as the Australian SKA Pathfinder (ASKAP).

In this event, five professional astrophysicists will discuss how astronomers map the Cosmos using the big data collected with optical and radio telescopes by large astronomical surveys. Hear about the exciting challenges in detecting planets around other stars, learn about how these studies allow us to understand the formation and evolution of galaxies, including our Milky Way, how we study dark matter and dark energy and, in summary, how astronomers search the skies to understand our position in the Cosmos. The panel will happily answer any questions about the Universe, so bring yours along.
