Astrophysics is the attempt to understand the physical processes at work in the Universe. It deals with questions such as, how do stars and galaxies form and evolve, and how are the components of a galaxy related to each other?

Stars, galaxies and gas clouds emit not only visible light but also radio waves, gamma rays, X-rays, and infrared radiation. Radio astronomers collect and process radio waves to make pictures of objects in space.

Six radio telescopes across Australia and New Zealand have joined forces to act as one giant telescope, linking up over a distance of 5500 km for the first time.

Following an extensive search and selection process, a senior researcher and university executive, Dr Philip Diamond, has been appointed Chief of CSIRO’s Astronomy and Space Science Division.

The HI Parkes All-Sky Survey (HIPASS) project gave us the first ever view of the Local Universe unobscured by galactic foreground stars and dust and mapped out the whole sky out to distances of about 150 megaparsecs.

An international team led by CSIRO astronomers is mapping the hydrogen gas in the Milky Way in unprecedented detail. This will help them learn more about how our galaxy formed.

CSIRO astronomers, using the Australia Telescope, have the skills to observe and understand cosmic objects ranging from forming stars to distant galaxies.

The 26th of February 2010 marks the 50th anniversary of CSIRO's partnership with NASA in solar system exploration. Learn more about our historic collaboration in this video. (7:08)

CSIRO’s Dr Naomi McClure-Griffiths has been dubbed the 'galactic octopus wrestler' after discovering a new spiral arm of the Milky Way and in this video podcast, she describes how it feels to uncover the secrets of the Galaxy. (3:10)

As a member of the project team working on the Square Kilometre Array, Mr Aaron Chippendale is bringing us a step closer to learning the secrets of life, the universe and everything.

Dr Dick Manchester is a CSIRO Federation Fellow, leading a team of astronomers that use radio telescopes to study pulsars, providing new insights into gravity and space.

In this Double Helix Science Club activity you'll learn how to make your own black hole clock and about different ways to keep time.
