High on the Antarctic Plateau, in one of the coldest places on Earth, a group of telescopes are peering through stellar dust clouds into the heart of our galaxy.
The cold helps counteract interference from the telescopes and surrounding equipment, which can hinder our ability to see relatively
‘cool’ objects in space, such as asteroids, young stars, and interstellar gas.
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.

Macquarie University astronomer Dr Stuart Ryder is in New Zealand to hitch a ride on a NASA jet and take a closer look at how stars are born in one of the most active stellar nurseries ever seen.
“We’re looking at a molecular cloud called BYF73, which is collapsing in on itself at extremely high speeds and forming massive stars,” says Stuart, who is an Adjunct Fellow with the Department of Physics and Astronomy at Macquarie University.

The pocket-sized CubeSats set out to study the thermosphere, the layer of Earth’s atmosphere between 90 and 600 kilometres above the ground that carries signals from GPS and other satellites.

But the new Australian National Concurrent Design Facility (ANCDF), housed at UNSW’s Canberra campus, speeds things up so a mission can be planned in weeks rather than months.
Harnessing the expertise, design processes and software of the French Space Agency CNES (Centre National d’Etudes Spatiales), the UNSW team has created Australia’s first concurrent design facility.
The ANCDF allows engineers and scientists—both professionals and students—to design different parts of a mission in parallel rather than one after the other, which is the traditional approach.
The first accurate 3D map of our galaxy reveals its true shape: warped and twisted.
Astronomers from Macquarie University and the Chinese Academy of Sciences have used 1339 ‘standard’ stars to map the real shape of our home galaxy in a paper published in Nature Astronomy today.
They found the Milky Way’s disc of stars becomes increasingly ‘warped’ and twisted the further away the stars are from the galaxy’s centre.
