Novel use of satellite data helping to keep tabs on our water

Understanding human impact on the water cycle is a tricky business - one clue is to be found in evapotranspiration. Novel use of satellite data is helping us measure something we can't see.

Fifty years ago Jocelyn Bell discovered pulsars and changed our view of the universe

In mid 1967, PhD student Jocelyn Bell at Cambridge University was helping to build a telescope. She went on to discover a little bit of "scruff" - the first evidence of a pulsar.

Putting satellite data into the hands of farmers

There's a high-tech tool increasingly available to farmers from Australia to Africa - remote sensing data from satellites. And they don't even have to leave the paddock.

Spotting algal blooms from space

In a world first, a satellite-based algal bloom alert system has been developed for inland water bodies - a giant leap forward from individually testing each dam, river or lake across the countryside, and allowing for a much quicker response.

Collecting satellite data Australia wants: a new direction for Earth observation

Australia will be able to guide the Earth observation satellite "NovaSAR" as it passes over our region - giving us a new level of control over the data we need to solve local problems.

NASA begins study of the Great Barrier Reef

It can be seen from space - the largest structure made of living organisms on Earth. Now the US space agency - NASA - is here to help scientists explore the link between changing conditions and coral health on the Great Barrier Reef.
