Astronomers have discovered enormous outflows of charged particles from the centre of our galaxy, moving at supersonic speeds.
Ants and termites could be pressed into service as tiny gold miners, say researchers, who have found them excreting miniature nuggets in their mounds.
Astronomers have snapped a supersonic jet of material blasting over two million light years from the centre of a distant galaxy.
Australian scientists have come up with a new theory to explain the eerie phenomenon known as ball lightning.
Astronomers have identified the first known 'middleweight' black hole, after spotting outbursts of super-hot gas with CSIRO's Australia Telescope Compact Array.
There's more atomic hydrogen in space than thought - but still not enough to solve the dark matter problem.
Dry places are getting drier and wet ones wetter, say scientists, as the global rainfall and evaporation cycle accelerates.
Galaxies are running out of the basic building blocks of stars. The universe is forming fewer stars than it used to, and an Australian research team says the reason is a shortage of molecular hydrogen.
Scientists are turning to the Australian and US navies to help protect them from Somali pirates in the western Indian ocean.
Using a CSIRO radio telescope, astronomers have caught an enormous cloud of cosmic gas and dust in the process of collapsing in on itself. They hope the discovery could help establish how massive stars form.
