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.
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

Sky survey provides clues to how they change over time.
The direction in which a galaxy spins depends on its mass, researchers have found.
A team of astrophysicists analysed 1418 galaxies and found that small ones are likely to spin on a different axis to large ones. The rotation was measured in relation to each galaxy’s closest “cosmic filament” – the largest structures in the universe.
Filaments are massive thread-like formations, comprising huge amounts of matter – including galaxies, gas and, modelling implies, dark matter. They can be 500 million light years long but just 20 million light years wide. At their largest scale, the filaments divide the universe into a vast gravitationally linked lattice interspersed with enormous dark matter voids.
Researchers hunt for a 12-billion-year-old signal that marks the end of the post Big Bang “dark age”.

across the Universe for 12 billion years, bringing them nearer to understanding
the life and death of the very earliest stars.

soon to be published in the Astrophysical Journal, a team led by Dr Nichole Barry from Australia’s University of Melbourne and
the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO
3D) reports a 10-fold improvement on data gathered by the Murchison Widefield
Array (MWA) – a collection of 4096 dipole antennas
set in the remote hinterland of Western Australia.
Australian-led astronomers find the most iron-poor star in the Galaxy, hinting at the nature of the first stars in the Universe.
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.
