How galactic winds stopped star formation. Strange radio emissions. Hercules stars and the evolving Milky Way. Find gravitational waves with pulsar timing.
8 July, 202523 September, 2025

National recognition for astronomers from Sydney, Canberra, Melbourne and Perth. The Astronomical Society of Australia (ASA) honours six astronomers at its Annual Scientific Meeting in Adelaide this week. “Our 2025 prize winners are investigating how galaxies form and evolve, and developing new tools to explore the cosmos. They are working with some of the most…

Too much heavy metal stops stars producing
11 January, 202220 September, 2022

Stars evolve according to the elements they manufacture Stars are giant factories that produce most of the elements in the Universe – including the elements in us, and in the Earth’s metal deposits. But what stars produce changes over time. Two new papers published in MNRAS shed light on how the youngest generation of stars…

Spin doctors: Astrophysicists find when galaxies rotate, size matters
16 November, 201919 February, 2020

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…
