Last night’s #auroras lit up skies across the world — and our community captured it all! Join us at 12:30 p.m. CST (18:30 UTC) as we share some breathtaking photos. We'll explain what caused this geomagnetic storm and whether the auroras might return tonight. Join us!

In 1826, Mary Shelly published her dystopian vision of the 21st century! I think she probably was a time traveler! #timetraveltuesday #reading #scifi #books #booksky

I loved this brilliant dystopian novel by @jmoodyburnbrush.bsky.social! It continues the story of memory manipulation in a divided society, as the characters face secrets while struggling for change! There’s even a little romance that works due to the truth of the emotions! #reading #books #booksky

We are pleased to announce our discovery of #GW241011 and #GW241110
Both come from binary black holes where one black hole is much larger than the other. The larger black holes have large spin. Could these black holes have formed in a previous merger?

Two #blackhole mergers, GW241011 & GW241110, detected a month apart in 2024 are helping scientists learn how black holes form, spin & evolve. Researchers from OzGrav & ANU, incl. PhD student Aswathi P Subhash & CI Dr Ling (Lilli) Sun contributed key analysis.

Writing update: I’ve finished a round of line editing, with some clunkiness reduced, some descriptions improved & some typos fixed while introducing new ones! 🙃🙂😵💫 It’s off to beta readers soon. I hope they like kidnapping, quantum teleportation, & time travel! #writing #wip #scifi #books #writersky

50 million light-years away, galaxy NGC 1097 & its tiny companion NGC 1097A are locked in a galactic embrace.
The bright knots around NGC 1097’s centre are thought to be large bubbles of glowing hydrogen gas about 750–2500 light-years across.
