INTEGRAL and Fermi-GBM detected a short GRB (or a giant magnetar flare) with a localisation that is perfectly consistent with the very close M82 galaxy! This could turn out as a very exciting event...
Sydney Friends! Come along to my next talk on the weird and wonderful Pulsar Planets!

Pass it on!
Outstanding shot of the #Sun rising behind ESO's Extremely Large #Telescope, currently under construction in #Chile. The dome is about 80 m tall; look at the size of those cranes! The ELT will have a 39 m primary mirror — the largest optical-infrared telescope in the world.

ARC are planning a 2-stage process for #DiscoveryProjects #DP25.
“Short” EOI in March, assessed by College of Experts, 30% team/70% project. 5000 expected, 20% success rate, outcomes in April.
Full apps: Same as current process but “streamlined”, 50% funded, outcomes in Nov.
Just catching up on the JWST SN1987A image!
It’s glorious!
In 1987, astronomers around the world witnessed a first in modern times - a nearby supernova.
One of the biggest mysteries to me is why we haven’t seen the neutron star or pulsar that formed during the event.
Wrote about this for #SpaceAustralia … you can read the feature article here: https://www.spaceaustralia.com/feature/did-1987-supernova-produce-pulsar
Also …. hurry up pulsar!
35 years ago, a bright new star appeared in a relatively close southern galaxy. A massive star had died in a spectacular supernova, providing astronomers with the first opportunity in about 400 years to study a relatively nearby event. But to this day, a mystery still remains – what did the supernova leave behind?
Rho Ophiuchi complex and the Dark Horse Nebula.
This was taken with a Nikon D750 and Nikon 50mm prime lens, mounted onto my Celestron astrophotography rig. 20x2.5 min frames.

Note to Mastodon users:
I've switched off cross-posting from Twitter. It wasn't working recently anyway, it seems.
I'll try my best to post to both platforms (Twitter & Masto) independently. I'm revamping my bot so it posts auto-tweets (e.g. outcomes) to both platforms simultaneously. Might be a bumpy ride, but we'll see.
I've grabbed an account on Threads, but there's no auto-posting for that yet, so I'm not active there. And Bluesky … if anyone has an invite, let me know! (Don't think there's auto-posting available there either?)
