Gamma ray bursts are the most explosive events in the Universe. Astronomers last year witnessed the brightest ever seen and have analysed the results, with a Sydney team providing important evidence. https://youtu.be/nwZSO6ULI2o Animation of a gamma ray burst forming.

Integrated Sustainability Analysis (ISA) group and the Sydney Institute for Astronomy (SIfA) have won the Innovation Award for the OAASIS project at the 2023 Anti-Slavery Freedom Awards. Slavery is far from an issue of the past, with nearly 50 million people across the world living in conditions of modern slavery

Alpha Centauri tantalisingly close to look for extra-terrestrial life Led by Professor Peter Tuthill, the TOLIMAN mission to search for planets capable of hosting life around Alpha Centauri has taken a step forward, engaging EnduroSat to take our technology into orbit. TOLIMAN Mission Leader Professor Peter Tuthill is from the

“Galactic cannibalism is how our universe grows” An international team of scientists led by a University of Sydney astrophysicist has discovered evidence the Andromeda galaxy is a cannibal growing through colossal intermittent feasts. The research, which is available on the pre-print server arXiv and will be published in the Monthly

In July, a puzzling new image of a distant extreme star system surrounded by surreal concentric geometric rungs had even astronomers scratching their heads. The picture, which looks like a kind of “cosmic thumbprint”, came from the James Webb Space Telescope, NASA’s newest flagship observatory. The internet immediately lit up

A study creates the first map of our galaxy’s ancient dead stars In the first map of the ‘galactic underworld’, a study from the University of Sydney has revealed a graveyard that stretches three times the height of the Milky Way. It has also indicated where the dead stars lie.

With the rapid development of stellar spectroscopy in the past decade, many stellar spectroscopic surveys, for example LAMOST, GALAH and APOGEE, combined with the astrometric information of Gaia have played a pivotal role in explaining the chemo-dynamic evolution of the Milky Way. By extracting the elemental abundances and ages of
