Children in remote and regional schools will soon be visited by astronomers bearing gifts in a quest to kindle interest in the cosmos.

The scientists – drawn from the ranks of the ARC Centre of Excellence for All Sky Astrophysics in 3D (ASTRO 3D) and the Australian National University – will donate a powerful telescope and high-tech accessories to each school so classes can continue to explore the Universe long after the astronomers have left.

Playing detective on a galactic scale: huge new dataset will solve multiple Milky Way mysteries

Australian-led GALAH project releases chemical information for 600,000 stars.

How do stars destroy lithium? Was a drastic change in the shape of the Milky Way caused by the sudden arrival of millions of stellar stowaways?

These are just a couple of the astronomical questions likely to be answered following the release today of ‘GALAH DR3’, the largest set of stellar chemical data ever compiled.

The data, comprising more than 500 GB of information gleaned from more than 30 million individual measurements, was gathered by astronomers including Sven Buder, Sarah Martell and Sanjib Sharma from Australia’s ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) using the Anglo Australian Telescope (AAT) at the Australian Astronomical Observatory at Siding Spring in rural New South Wales.

Blinded by the light no more: simulations show NASA’s James Webb Telescope will reveal hidden galaxies

Australian researchers find ways to overcome the blinding glare of quasars

NASA’s James Webb Space Telescope will uncover galaxies never before seen by humanity, Australian-led research reveals.

The telescope, due to launch in late 2021, is the largest, most powerful and complex space telescope ever built.

Two new studies led by Madeline Marshall from Australia’s University of Melbourne and the ARC Centre of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) find that the Webb will be able to reveal galaxies currently masked by powerful lights called quasars.

Can you see the stars?

Who has the darkest skies?

Tell us what you can see on the longest night, help us map Australia’s light pollution, and set a world record

Scientists are asking all Australians to step outside on the longest night of the year to help them measure light pollution around the country.

“We’re expecting thousands of people to join us on Australia’s longest night, Sunday 21 June, to help researchers create a map of Australia’s darkest skies, and learn about light pollution and its effect on people, animals, and astronomy,” says Marnie Ogg, CEO and founder of the Australasian Dark Sky Alliance.

Hungry galaxies grow fat on the flesh of their neighbours

Modelling shows big galaxies get bigger by merging with smaller ones

Galaxies grow large by eating their smaller neighbours, new research reveals.

Exactly how massive galaxies attain their size is poorly understood, not least because they swell over billions of years. But now a combination of observation and modelling from researchers led by Dr Anshu Gupta from Australia’s ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) has provided a vital clue.

Star-quake vibrations lead to new estimate for Milky Way age

Data gathered by NASA’s now defunct Kepler telescope provides a solution to an astronomical mystery.

Star-quakes recorded by NASA’s Kepler space telescope have helped answer a long-standing question about the age of the “thick disc” of the Milky Way.

In a paper published in the journal Monthly Notices of the Royal Astronomical Society, a team of 38 scientists led by researchers from Australia’s ARC Centre of Excellence for All Sky Astrophysics in Three Dimensions (ASTRO-3D) use data from the now-defunct probe to calculate that the disc is about 10 billion years old.

Anaemic star carries the mark of its ancient ancestor

A newly discovered ancient star containing a record-low amount of iron carries evidence of a class of even older stars, long hypothesised but assumed to have vanished.

In a paper published in the journal Monthly Notices of the Royal Astronomical Society: Letters, researchers led by Dr Thomas Nordlander of the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) confirm the existence of an ultra-metal-poor red giant star, located in the halo of the Milky Way, on the other side of the Galaxy about 35,000 light-years from Earth.
