It’s the gayest week of the year, here in Sydney! 🏳️🌈🏳️⚧️
Lots of fun festival events, culminating in one of the largest queer events across the world — the Sydney Mardi Gras this Saturday.
Have updated my banner to be this gorgeous image from Alex Cherney of CSIRO’s ASKAP in Pride colours.

A unique celestial object, known as ASKAP J1832–0911, is capturing the attention of astronomers.
Discovered 15,000 ly from Earth, this enigmatic object, located in our galaxy, behaves in a way never seen before.

Hear from Joshua, the first author of the latest ASKAP discovery! Interviewed by Dr Kirsten Banks for @ozgrav.bsky.social 🌟🔭🧪
This student just had their first paper published in Nature Astronomy! Joshua Lee and his team discovered a rotating object in space that's spinning oddly slowly.

When we search for radio transients we exclude extended objects
Hence we discard lots of radio galaxies, like the ones in this ASKAP VAST gallery, compiled by PhD student Surabhi Chandra
Each image shows radio emission from a galaxy with a supermassive black hole at the centre

A research team discovered a 160,000-light-year-long bridge of neutral hydrogen gas (HI) connecting two dwarf galaxies, NGC 4532 and DDO 137.
This thanks to the WALLABY project, which utilizes the ASKAP telescope in Australia.

NASA just picked up a cosmic signal from deep space that blinks for 2 minutes every 44. It’s called ASKAP J1932-0911 and it shoots out X-rays and radio waves for up to 5 minutes at a time. Not a pulsar, not a black hole, maybe a dead star pinging us.

Uzaydan Dünyaya sinyal gönderen bir cisim fark edildi.
ASKAP J1832-0911 adı verilen cisim, her 44 dakikada bir, iki dakika boyunca radyo dalgaları ve X ışınları yayıyor.
Aq Akp yetmedi bir de uzaylılarla mı uğraşacağız ?!

We've discovered another long period transient with ASKAP!
Source #15 in this small but growing population.
It repeats every 36 minutes, but despite many observations (see plot) we're not sure what it is.
