With this year’s version, we’re delivering much more than just another yearly release. Supernova represents a modernized overhaul of the software – both visually and technically – while retaining the familiarity and flexibility you expect.
It's your first step into the future of Thunderbird.
A new Type II core-collapse Supernova SN 2023ixf was detected yesterday in the Pinwheel Galaxy (aka Messier 101, M101 and NGC 5457).
At 21 million light-years distance and only 14.9 mag, it is too far and too faint to stand out in the night sky, unlike some other supernovae observed by humans over the past few thousand years.
However, it is of great interest to the astrophysics community.

A bright supernova just popped off in nearby galaxy M101! Not naked-eye bright, but should be visible through a decent amateur telescope.
M101 is about 21 million light years away, so this signal has been on its way to Earth for a looong time. https://www.wis-tns.org/object/2023ixf/discovery-cert#Supernova#M101#Astrodon
I have been using @thunderbird for the longest time now since I ever needed email. To be honest I've used it when I needed to then left, but something always brought me back to #Thunderbird.
Recently I found out about the #ThunderCast#podcast and it's great to hear from this open source team and the time and energy to keep it modern. Just updated to the #SuperNova 115 version and it's awesome!
The podcast is where I learned Thuderbird has addons too!
There are better pictures of NGC4216, a Galaxy you can find in Virgo’s Constellation. My idea, however, to capture it was two-folded: to capture it “as it appears to be” from my rooftop in Mexico City, but mostly to capture and understand the supernova explosion that happened there a few weeks ago and that you can find (WOW!) in my photograph.
A new #JWST view of the remnant of Supernova 1987A.
SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. Located 168,000 light-years away in the Large Magellanic Cloud, it was the nearest supernova to explode in the era of modern telescopes.
Preliminary report of the discovery of a probable nova in M31 (the Andromeda Galaxy) on 2023 May 28.063 UT by astronomers using the 0.65-m telescope at Ondrejov, Czech Republic.
The object designated PNV J00421981+4107048 is located at R.A. = 0h42m19s.81, Decl. = +41o07'04".8, which is 276.7" west and 543.7" south of the center of M31. Mag 18.1 in R.
M31, at 2.5 million light-years distance, is the closest major galaxy to the Milky Way.
I finally managed to process my own image of the #SN2023ixf supernova in #M101.
Crazy to think this event actually happend some 21 million years ago, but we can still observe it changing brightness in mere days.
Observations of the #supernova#SN2023ixf "were the earliest-ever measurements of polarized light from a supernova, showing more clearly the evolving shape of a stellar explosion".
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.
We want you to have a great experience on Thunderbird, and that means fonts that are the perfect size and density for you. Find out how to go from "too small" or "too big" to just right in our latest blog post - and dig in to the technical details behind any trickier issues in the linked KB article.
Thunderbird has come a long way and it's now an actually decent email client on #Linux with full calendar support. Previously I used Evolution, but that was really stuck in the past. This is good.
Now I need to check if the @protonmail plugin works in Linux and I'm set!

Archaeologists have discovered a 2,400-year-old stone map of the night sky in Italy. The map shows 29 stars carved on a circular stone, including Orion, Scorpius and Pleiades. The map is very accurate, except for one mysterious star that might have been a supernova or a black hole. 🌠🌠🌠
I don't talk about astronomy nearly enough, so let's change that!
One of the most groundbreaking developments in astronomy has been the absolutely mind-blowing work the James Webb Space Telescope has been putting out in a fraction of the time it took the old Hubble Space Telescope to produce similar work. Here are a couple of recent images I find particularly remarkable.
S1 LMC N79 – Dorado
Honestly, this image is just beautiful to look at. It’s even more breathtaking when you consider that this is just one cloud within this star-forming region of the Large Magellanic Cloud, which itself is an irregular galaxy located about 163,000 light-years from Earth. If you live in the Southern Hemisphere and find yourself a suitably dark place, you can gaze up and see this whole other galaxy as a milky blotch in the night sky.
A gravitationally lensed supernova in MRG-M0138 – Cetus
It's pretty wild seeing the immense force of gravity contained within these galactic clusters warp distant points of light in these visually striking ways. Each arc is a galaxy far beyond the cluster itself that allow us to peer further back in time. Sometimes these warped images mirror themselves on the complete opposite side of the cluster, like ripples on a pond. In the case of this distant supernova, the light emanating from that cataclysmic event is being reflected in such a way that it's reappearing further down the length of the arc, making it seem as though there are two supernovae happening when in fact they are the same.
