Once again, don’t trust the output of any #AI assistant without verification. This is not the HR 8799 exoplanet system, it’s the YSES 1 exoplanet system.

"Merger of two massive black holes is one for the record books"
@JenLucPiquant reports on our LIGO Virgo KAGRA discovery of #GW231123
This morning's noctilucent cloud.
02:42 to 03:08, Fife in eastern #Scotland.
💥💥 Double detonation!
For the first time, astronomers have obtained visual evidence that a star met its end by blasting twice.
This was done by studying the centuries-old remains of supernova SNR 0509-67.5 with our Very Large Telescope. Led by the Univ. of South Wales, this shows some of the most important explosions in the Universe in a new light.
What happened exactly? Keep reading.

Fascinating: ESA is now preparing the Comet Interceptor mission
The spacecraft will be launched in 2029 into a parking orbit, lying in wait for a suitable target – a pristine comet from the Oort Cloud, or, unlikely but highly appealing, an interstellar object.

ESA tracks rare interstellar comet
Astronomers have confirmed the discovery of a rare celestial visitor: a comet from beyond our Solar System. Named 3I/ATLAS, this newly identified interstellar object is only the third of its kind ever observed, after 1I/ʻOumuamua in 2017 and 2I/Borisov in 2019.

This is my second migration on Mastodon, so I think an Introduction might be in order. I'm moving in to this account (that had lived independently, to test some of Mathstodon features) after astrodon.social is being sunset. Hope that Astrodon as a concept still lives!
I currently work in Systems Engineering for radio telescopes (in particular, the ALMA radio interferometer). I’ve also worked in software development and management for the SKAO observatory, and for the archive department at ESO. Of course, I'm also very interested in math (specially that having to do with system theory), so I'll try to get a bit stronger there.
Glad to see you all around!

Chaos, panic, total devastation: #asteroids in films are devastating, and only an unlikely, heroic mission can save humanity.
But what would happen if an #asteroid hurtled towards us for real?
On the occasion of #AsteroidDay, tune in to Chasing Starlight to find out:

One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!
We’re looking forward to chatting with all of you about #astronomy
