Are we alone? University and EnduroSat join up in search for life among the stars
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

A dark stream sheds new light on the life of galaxies
“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

Alien megastructures? Cosmic thumbprint? What’s behind a James Webb telescope photo that had even astronomers stumped
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
Milky Way’s graveyard of dead stars found
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.
Measuring reliable stellar abundances towards crowded regions using MUSE
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
