Each year, the Earth runs through a broad river of dust surrounding Comet Halley – giving birth to the spectacular Eta Aquariid meteor shower.

Penguins will have the best seat in the house as a total solar eclipse passes over Antarctica on December 4. Australia and New Zealand will experience a minor partial eclipse, but not a noticeable one.

A partial lunar eclipse during moonrise will let viewers in most Australian capitals see the Moon partly shrouded in Earth’s shadow, while the “Moon illusion” makes it look larger than life.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?

Sonar scans of the Indian Ocean floor south of Christmas Island have revealed a Tolkeinesque landscape of towering peaks, ashen uplands and ominous volcanic craters.

Ophiojura, discovered living on a seamount deep in the Pacific Ocean, is the last known survivor of a unique group of animals that diverged from its closest relatives way back in the Jurassic period.
Ancient climate change doomed the monk seals that lived in Australian waters millions of years ago.
After more than 300 years of effort, scientists have documented fewer than one-third of Australia’s species. The remaining 70% are unknown, and essentially invisible, to science.
There are too many little-understood species for scientists to study them all. A new approach helps decide which ones to tackle first.

Of the three probes to reach Mars this month, only two will land. But they will add to our growing knowledge of the red planet, and the search for evidence of life.
A poor start for meteor showers in 2021 but things get better with a possible spectacular surprise later in the year. Here’s your guide on when and where to look to catch nature’s fireworks.

We recorded the largest number of bigfin squids ever seen in one area. Before this, this rather elongated creature had only been spotted a dozen times across the globe.

This newly discovered ancient monk seal is challenging previous theories about how and where monachine seals evolved. It’s the biggest breakthrough in seal evolution research in about 70 years.

Meteor telah dapat dilihat sejak dahulu kala. Meteor terdiri dari potongan puing-puing, biasanya tidak lebih besar dari butiran debu atau pasir, yang terus-menerus menabrak atmosfer bumi. Ketika puing-puing…

Our new research has more than doubled the known fossil record of seals in Australia.
“I arrived in Perth and bought a foam mattress for the back of my car – my bed for half of the trip. I stocked up on tinned food, and I headed north in search of these tiny eight-legged gems.”
Aerial baiting has been Australia’s foremost weapon against pest species for the past 74 years. But at what cost?

A big year ahead for some of the meteor showers this year. Here’s your 2020 guide on when and where to look to catch nature’s fireworks.
