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.

Orbits of ancient stars prompt rethink on Milky Way evolution

Australian telescopes and European satellite combine to reveal unexpected motions among the Galaxy’s rarest objects

Theories on how the Milky Way formed are set to be rewritten following discoveries about the behaviour of some of its oldest stars.

An investigation into the orbits of the Galaxy’s metal-poor stars – assumed to be among the most ancient in existence – has found that some of them travel in previously unpredicted patterns.

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.

Elements of surprise: neutron stars contribute little, but something’s making gold, research finds

Colliding neutron stars were touted as the main source of some of the heaviest elements in the Periodic Table. Now, not so much

Neutron star collisions do not create the quantity of chemical elements previously assumed, a new analysis of galaxy evolution finds.

The research also reveals that current models can’t explain the amount of gold in the cosmos – creating an astronomical mystery.

The work has produced a new-look Periodic Table, showing the stellar origins of naturally occurring elements from carbon to uranium.

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.

Astronomers see ‘cosmic ring of fire’, 11 billion years ago

Unusual galaxy set to prompt rethink on how structures in the Universe form

Full paper, Full video, and images available. Details below.

Astronomers have captured an image of a super-rare type of galaxy – described as a “cosmic ring of fire” – as it existed 11 billion years ago.

The galaxy, which has roughly the mass of the Milky Way, is circular with a hole in the middle, rather like a titanic doughnut. Its discovery, announced in the journal Nature Astronomy, is set to shake up theories about the earliest formation of galactic structures and how they evolve.

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.

Canberra astronomer becomes first Australian to win major US science award in 133 years

Lisa Kewley has transformed our understanding of the early years of the Universe, the development of galaxies, and what happens when they collide.

For her pioneering investigations across theory, modelling and observation, she will receive the US National Academy of Science’s biennial James Craig Watson Medal in Washington DC.

“At school I thought physics would be too hard.  But I had a wonderful physics teacher whose love for astronomy was contagious!” says Lisa.

Hire more LGBTQ and disabled astronomers or risk falling behind, review finds

Analysis finds gender equity among star scientists improving, but big challenges remain.

Ensuring research opportunities for indigenous, disabled and LGBTQ astronomers is essential if Australian research is to succeed in the new era of “mega-telescopes”, a major analysis has found.

In a paper published in the journal Nature Astronomy, Professor Lisa Kewley, director of the ARC Centre of Excellence in All Sky Astrophysics (ASTRO 3D), finds that encouraging astronomers from marginalised communities will increase the chances of significant research discoveries.

“Studies show that increased diversity up to the highest levels of organisations, and effective diversity management, leads to organisations outperforming their competition in innovation, productivity and profit because more ideas are produced,” she says.
