New formula for Earth?

Planet Earth

Current theories claim Earth's composition should be the same as the composition of chondritic meteoroids. Dr Ian Campbell and Professor Hugh O'Neill from the Australian National University discuss evidence against a chondritic Earth in their paper in Nature.

Square Kilometre Array decision delayed

With only two contenders: South Africa and Australia/New Zealand to be the hosts for the world’s biggest telescope, competition between the countries is tight for this mammoth research project. Members will meet in Amsterdam on 4 April to further discuss the bid. CSIRO’s new ASKAP antennas

Refining Earth’s Clock: 700, 000 years younger?

New research has revealed that some events in Earth's history happened more recently than previously thought. Scientists from the British Geological Survey and the Massachusetts Institute of Technology, publishing recently in the journal Science, have refined the data used to determine how much time has passed since a mineral or rock was formed.

Time Travellers take us to the beginning

Australia- Time Travellers Guide

Dr Richard Smith presents Australia: The Time Traveller’s Guide. If you haven’t caught episode 1 of this series, it isn’t too late. Starring the Australian continent, on the ABC you can catch up through iView or buy the series. Numerous GSA members have contributed in their field of expertise.

Time Traveller’s interactive website

If the series isn’t enough, there is also a website where you can explore deep time, download wallpapers, explore animated creatures, take quizzes and much more!

This is a fun tool to engage young and not so young minds in the geosciences.
