Supernova #SN2023ixf is the brightest, nearest supernova seen in nearly a decade. Here's a map of our cosmic neighborhood to show what "near" means to a cosmologist. The supernova is in galaxy M1010; the map is about 40 million light years across.

Endlich hat das Wetter ein Einsehen und wir haben die am 19. Mai 2023 entdeckte #Supernova in #Messier 101 fotografieren können. Vielleicht hält das Wetter und wir können am Samstag zu unserem #Beobachtungsabend im #Astronomiemuseum einmal einen Blick riskieren. #Sternwarte #Sonneberg

AAVSO finder chart for the field of #supernova #2023ixf in #M101, plotted with a 1º field of view and a limiting magnitude of 14. Comparison star magnitudes are shown without decimal points, so, e.g., "119" = magnitude +11.9.

The Magnificent Five Images of #SupernovaRefsdal - Time Delay and Magnification Measurements: https://iopscience.iop.org/article/10.3847/1538-4357/ac4ccb -> "We apply four separate techniques to perform a blind measurement of the relative time delays and magnification ratios between the last image SX and the earlier images S1–S4. [...] This corresponds to a 1.5% precision on the time delay and 17% precision for the magnification ratios and includes uncertainties due to millilensing and microlensing."

@supernovae following up: here's the moderation stuff i was working on. shelving it to get back to Feditext. might be useful to others.
• https://github.com/VyrCossont/m1000 implements a webhook listener automod bot in Rust which automatically creates reports when posts or users match on configurable words, regexes, or link domains. should be able to handle another #thegx situation, or a small link-spam campaign. proof of concept, not quite prod-ready, but i'm already running it on my home instance.
• https://github.com/VyrCossont/mastodon/commit/df8be12f1190769aa530590163f9cbf56294dd52 removes the `if local?` check from Mastodon's `status.*` and `account.*` webhooks, allowing `m1000` to moderate remote posts and users.
• https://github.com/VyrCossont/mastodon/commit/528afe989e1aa1e1a1069e2f420c498e78fc9f08 adds a `report.updated` webhook to Mastodon, useful for integration with external ticketing systems.
• https://github.com/VyrCossont/mastodon/commit/0a869f0d31e6ecbf57d25451ab60b52bf35730d8 creates an API for Mastodon's audit log, which currently doesn't have one. this would be useful for admin apps.

@supernovae being the person who contributed those webhooks, i'm in favor, obviously.
my next steps would be:
- patch out the `if local?` checks on them so tools can see incoming remote posts as well as local posts.
- build a basic tool that does keyword, regex, and link domain matching on posts and their accounts to report posts for mod review. this is still reactive tooling with no feedback loop, but we need to be able to handle situations like #thegx, but only when it's that clear-cut should there be an automatic action.
- train mods to reclassify reports as related to spam or specific rule violations before closing them. this lets us start building a training set of closed reports and their resolutions: was this post actually spam?
- connect the tool to a content-based filtering package like rspamd or SpamAssassin so it can start learning. both of these also integrate with existing email spam blocklists, so we'd also get some benefit from email spam campaign link blocklists, etc.… -

@supernovae On #Mastodon, I'd love to be able to follow an account in a #list without needing to also follow them in my "Home" #timeline. On #Twitter I follow thousands of accounts only in #lists and have written about this in https://www.ii.com/twitter-lists-i-follow/ and https://www.ii.com/twitter-lists/. Thanks for asking🐘 😍

All of the above. :):):)
Apart from #TomPeters and maybe @james, most people I know don't Thrive on #Chaos.
(Fun fact: All systems involving humans are #complex, in turn determined by a chaotic attractor defining its future development paths. 😉...I hope I remember this correctly.)

Yes*, absolutely.
As one of my mentors, who had seen the rise of Silicon Valley, used to say:"You have to take #complexity away from the end-user and put it behind the #MMI."
This is possible for access points (apps) to the #Fediverse as well.
*"it can give the appearance of simplicity and expected behaviors "good enough" - so that we can... is "easy".

Op een nieuwe, gedetailleerde foto van de James Webb-ruimtetelescoop is een ster te zien, relatief kort voor explosie in een zogenoemde supernova. Dit fenomeen wordt niet vaak gezien.

Hey, what's your top 3 recommendations for:
1. Aspiring mastodon designers
And if different
2. Aspiring mastodon admins?

Eine Supernova erleuchtete im Jahr 1181 den Himmel und hinterließ einen einzigartigen Überrest. In dessen Zentrum verbirgt sich ein Stern, der die gewaltige Explosion überlebt hat.
Ein beispielloses Sternen-Feuerwerk

#Supernovas are bright.
So bright that when you hold a nuclear bomb directly to your eye - compared to that the sun going Supernova would be a billion times brighter.

@supernovae Ok, think about it THIS way: if you do not know the EXACT words to use in a hashtag, you are going to miss a lot of content. Examples: #CovidIsNotOver ##COVIDisAirborne #LongCovidIsNotAJoke
If we had better search functions we could simply type in the word Covid and see anything vaguely related to Covid.
