What is a solar eclipse?
Discover how the Sun, Moon and Earth form one of the most spectacular astronomical events you may ever see, by turning day into night.
Transit of Venus 2004
Watch a video replay (no audio) of a webcast recorded from Canberra, Australia, which shows the transit of Venus across the face of the Sun in June 2004. (14:00)
Transits of Mercury and Venus
Discover why the planets Mercury and Venus are the only two planets to transit the Sun, when viewed from the Earth, and why transits of Venus are rare.
Super-fast chips boost telescope’s power
Recent changes to CSIRO’s Australia Telescope have made one of the world’s most advanced radio telescopes even more powerful.
CSIRO has boosted the power of its Australia Telescope through chips made of an advanced semiconductor material, indium phosphide.
Studying cosmic objects
CSIRO astronomers, using the Australia Telescope, have the skills to observe and understand cosmic objects ranging from forming stars to distant galaxies.
CSIRO astronomers have the skills to study objects ranging from individual stars to the distant Universe.
Discover how to split white light into a rainbow of colours.
Build a solar viewer
Discover how you can build a solar viewer that will allow you to safely view an image of the Sun.
Searching for new galaxies
An Australian-led team of astronomers has found faint galaxies previously hidden behind the dust and gas of our own Galaxy.
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.
Searching for gravity waves
The Parkes Pulsar Timing Array project may give the first direct detection of gravity waves from space.
Australian researchers are working with international colleagues to detect gravity waves from space using pulsar timing observations at the Parkes radio telescope.
Summer scholarships in space

Undertake a research project with a research scientist or outreach specialist at CSIRO Astronomy and Space Science.
Australia’s isolation creates better scientists
Federation Fellow Ron Ekers believes Australia’s isolation creates better scientists.Former CSIRO scientist and current President of International Astronomers Union, Professor Ron Ekers argues that multi-culturalism makes science more fertile and Australians working overseas are our link to the global science community.
Radio astronomy: seeing the invisible universe
Radio astronomers collect and process radio waves to make pictures of objects in space.
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.
