Humans have been predicting eclipses for thousands of years
The coastal town of Exmouth in Western Australia is due to experience one of the most spectacular astronomical phenomena on April 20 2023 – a total solar eclipse. Eclipses have entranced us for millennia. But it turns out calculating exactly when and where we can watch an eclipse in its full glory can be surprisingly hard. Watching the Sun and the Moon Being so dominant in the sky, the Sun and the Moon were the most captivating celestial bodies for ancient cultures to observe.

THE CONVERSATION: Some black holes are anything but black – and we’ve found more than 75,000 of the brightest ones
Because of this, it’s impossible to directly image black holes, making them mysterious and quite perplexing. But our new research has road-tested a way to spot some of the most voracious black holes of all, making it easier to find them buried deep in the hearts of distant galaxies. Despite the name, not all black holes are black. While black holes come in many different sizes, the biggest ones are at the centres of galaxies, and are still growing in size.
Some Black Holes Are Anything But Black-and Scientists Found 75,000 of the Brightest Ones
When the most massive stars die, they collapse to form some of the densest objects known in the universe: black holes. They are the “darkest” objects in the cosmos, as not even light can escape their incredibly strong gravity. Because of this, it’s impossible to directly image black holes, making them mysterious and quite perplexing.

How can astronomers reduce carbon emissions and be more environmental
Astronomers know all too well how precious and unique the environment of our planet is. Yet the size of our carbon footprint might surprise you. Our study, released today in Nature Astronomy, estimated the field produces 25,000 tonnes of carbon dioxide-equivalent emissions per year in Australia. With fewer than 700 active researchers nationwide (including PhD students), this translates to 37 tonnes per astronomer per year.
Astronomers create 40% more carbon emissions than the average Australian. Here's how they can be more environmentally friendly
