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.

Splitting light

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.
