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. The first map of the …
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 millions of stars from the …
Event Horizon Telescope set to reveal ‘exciting results’ about the black hole at the centre of the Milky Way
There’s a monster lurking in the heart of our galaxy, and we may get our first glimpses of it tonight. At 11pm AEST, an international team of scientists will reveal what they’re calling a “groundbreaking” discovery from our galactic centre — and you’ll be able to watch it live. There are rumbles the Event Horizon Telescope …
Playing detective on a galactic scale: huge new dataset will solve multiple Milky Way mysteries
Australian-led GALAH project releases chemical information for 600,000 stars. 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 the release today of ‘GALAH DR3’, …
