New technique helps NASA’s James Webb Space Telescope Astronomers have turned a cluster of galaxies into a gargantuan magnifying lens, using it to study another galaxy, 10.7 billion light years away, in unprecedented detail.
Galaxies with extended disks maintain productivity, research reveals Image, video, GIFs Paper details, authors and affiliations More about ASTRO 3D Media release below Massive galaxies with extra-large extended “puffy” disks produced stars for longer than their more compact cousins, new modelling reveals. In a paper published in the Astrophysical Journal, researchers led by Dr Anshu…
Completion of Australian-led astronomy project sheds light on the evolution of the Universe Image, video, GIFs Paper details, authors and affiliations More about ASTRO 3D Media release below The complex mechanics determining how galaxies spin, grow, cluster and die have been revealed following the release of all the data gathered during a massive seven-year Australian-led…
Australian telescopes and European satellite combine to reveal unexpected motions among the Galaxy’s rarest objects Image Additional Information Media release below 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 –…
Australian-led GALAH project releases chemical information for 600,000 stars. Image Additional Information Media release below 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…
Full paper available here, read on for media release, photos, captions and background information. 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….
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…
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…
