The discovery of a piece of geyserite found in hot springs environment has changed our thinking our thinking about the origins of life on earth - and has implications for the search for life on Mars.

If there ever was life on Mars it may still be there, writes Malcolm Walter. And if we can demonstrate an independent origin of life, the consequences will be profound.


One of the best ways to find out the challenges of living on Mars is to simulate living on another planet here on Earth, writes Jonathan Clarke.


As part of National Science Week, a panel of leading scientists including Paul Davies and UNSW's Martin Van Kranendonk will address some of space exploration's biggest questions at the Sydney Opera House.


Life on the land could have started millions of years earlier on Earth than first thought. This could change the way we think about life developing elsewhere in the universe, writes Tara Djokic.


Fossils discovered by UNSW scientists in ancient hot spring deposits in the Pilbara have pushed back by 580 million years the earliest known evidence for microbial life on land.
