Hmmm...

Time to see how well I can replicate either the #Chromevox and/or #Talkback keyboard experience with the #jieshuo screen reader's 'Hotkey Scheme' feature. The default has 'waaaaaaaay' too many conflicts in my view (particularly if using web browsers that support keyboard shortcuts).

And since people are able to share said keyboard layouts, anyone thought of creating a #WindowEyes or #SuperNova/#Hal layout?

Our new guide introduces you to all the elements of Thunderbird's main window, in its Classic layout AND the new Supernova layout.

Let's get you familiar with the terminology, and help you navigate Thunderbird like a pro!

We're experiencing some issues with site build system and trying to get 115 into your hands. It wouldn't be a major release without some hiccups! Thanks for your patience folks.

@thunderbird I've already gotten my hands on #Thunderbird 115 #Supernova and I can tell you: it's worth the wait 💙! The team has done a terrific job of making frontend and backend improvements while maintaining and even extending customizability 👏!

Mind you that the #Cardbook add-on hasn't been updated yet to be compatible with this release. You can use the built-in contacts manager however. Maybe now is the perfect time to back-up your contacts (export to .vcf files) and TB profile?

Beteigeuze: Gewaltige Supernova doch viel näher als angenommen?

Laut einer neuen Studie dürfte Beteigeuze in wenigen Jahrzehnten und maximal Jahrhunderten explodieren. An der Interpretation gibt es aber bereits Kritik.

After many years of using @thunderbird, hoping and waiting for a redesign (those two lines in the messages column in vertical view!), I finally made peace with @EvolutionGnome... on the very same day the launching of #supernova was announced 🤷‍♂️ And now, who do you love more, mum or dad?

Doubts aside, what a blessing to have those two such fantastic #email clients available on #Linux.

Dust or bust! ... or, rather, Bust and Dust!!

New observations & findings from #JWST of 2 Type II supernovae. See link below to learn why space dust is important.

My Favorite #Firework ...

On July 4 "{i}n 1054, Chinese astronomers took notice of a 'guest star' that was, for nearly a month, visible in the daytime sky. The 'guest star' they observed was actually a #supernova explosion, which gave rise to the #Crab #Nebula, a six-light-year-wide remnant of the violent event." The nebula was discovered by English astronomer John Bevis in 1731.

Happy birthday to the Crab Nebula supernova remnant. Light from this exploding star was first seen on Earth on 4 July 1054.

The AAVSO light curve of #supernova #2023ixf to date shows the fireball continuing to redden (i.e., it's getting fainter at blue wavelengths more quickly than in the red). There's still some subtype uncertainty; how this proceeds will determine if it's a IIP or a IIL. #astronomy

Quick FYI 🏁 🏎️

Prior to #GoDaddy killing my #POP #Email client access on June 2 as part of #Microsoft's mandate to force users onto its #Exchange protocol, I switched from #Outlook 2016 to #Thunderbird 114 Beta (which still connects w/ #POP3 + #OAuth2 - unsure if it's a glitch, but it works)

Thunderbird 114 Beta Portable (it's the version I'm using)

Since Thunderbird team is moving towards its new #Supernova #UI for Thunderbird 115, there's a mixture of old & new menus

18 days after it exploded on May 19, supernova SN2023ixf in the Pinwheel Galaxy M101 seems to be dimming a bit, as all Type II SNe do, gradually over a period of several months.

Note that an increase in magnitude by 1 implies a decrease in luminosity by a factor of 2.512.
Pre-explosion mag was ~24.
See this thread https://fosstodon.org/@AkaSci/110402301121258093 for more info on SN2023ixf.

Here is some data on the change in brightness of a few past supernovae.

Luminosity of a Type II SN rises for 1-3 weeks and then declines over months.
Type II-L SNe have a steady decline rate, while Type II-P supernova exhibit an intermediate plateau period with a reduced decline rate.
The average decay rate of 0.008 mag per day is much lower than that of Type Ia SNe.

WRITER FUEL: NASA's James Webb Space Telescope has snapped a picture of WR 124, a rare Wolf-Mayet star 30 times the size of our sun, ejecting a luminous cloud of cosmic dust as it starts to go supernova.
