ASTRO 3D has worked with Science & Medicine at ANU to include its popular Smartphone Spectroscope activity in the 2024 STEM Boxes initiative for schools for NationalScienceWeek. Check out Ella Wang demonstrating how spectroscopy works. 🏳️‍🌈💫 youtu.be/V7tKLrTmzCQ?si…

Interesting new result from our Maximilian Häberle, Nadine Neumayer and colleagues: in a needle-in-a-haystack process using mostly archival data, they found fast-moving stars indicating the presence of an intermediate-mass black hole in omega Centauri mpia.de/news/science/2…

Are you ready for GALAH Data Release 4? 1st October!

GALAH DR4 is now public! 10 years of observations, 995 nights (incl. rainy/snowy/cloudy ones), 32 elements (incl. nitrogen), 0.92 Mio. stars, 1.09 Mio. spectra, thanks to an amazing group of observers, engineers, and astronomers. Paper: arxiv.org/abs/2409.19858 with links to data.

It is time to pick the newest "Astro Plot of the Week"! Pick one: - Plot from Buder et al. (arxiv.org/abs/2409.19858) - Plot from Schouws et al. (arxiv.org/abs/2409.20549) Poll (below) is open for two days - vote!

Thanks so much Astro Plot of the Week and those who voted - but also how exciting are these amazing results coming out of JWST? Well done Sander Schouws, 🇺🇦 Rychard Bouwens #IStandWithUkraine, and team.

The GALAH DR4 data release is out! ONE MILLION STARS! Here's our modified element table (including our data for 30 elements) - figure by Sven Buder. The other figures show theoretical time dependencies from Kobayashi, Karakas & Lugaro 2020. GALAH Survey Sydney Institute for Astronomy (SIfA)
