The modern-day space race has led to thousands of satellites being scattered through Earth’s outer orbits. If left unchallenged, these companies risk overpopulating an already crowded space environment – potentially pushing dark skies to extinction.

Mention the superb lyrebird, and you’ll probably hear comments on their uncanny mimicry of human sounds, their presence on the 10 cent coin, and their stunning tail. Far less known – but equally, if not more, impressive – is the Albert’s lyrebird.

Within half a century, Australia’s blue-grey mouse had seemingly disappeared, leaving behind only three scientific specimens. But is the mouse extinct, or just extremely hard to find?

The world has its best chance yet to reduce greenhouse gas emissions quickly, but hard and fast cuts are needed across all sectors and nations to hold warming to safe levels, the global authority on climate change says.

Humanity still has time to arrest catastrophic global warming – and has the tools to do so quickly and cheaply, the Intergovernmental Panel on Climate Change (IPCC) has found.

As coal-fired climate change makes bushfires in Australia worse, governments are ramping up hazard-reduction burning. But new research shows the practice can actually make forests more flammable.

After the devastating floods, it’s hard to imagine only two years earlier many hard-hit communities suffered extreme heat, drought and unprecedented bushfires. Yet a report, released today, shows Australia’s environment has recovered dramatically since then.

Foxes kill about 300 million native mammals, birds and reptiles each year, and can be found across 80% of mainland Australia, our devastating new research published today reveals.

At any one time, Earth’s atmosphere holds only about a week’s worth of rain. But rainfall and floods have devastated Australia’s eastern regions for weeks and more heavy rain is forecast. So where’s all this water coming from?
