Sharpless 249 and the Jellyfish Nebula

Explanation: Normally faint and elusive, the Jellyfish Nebula is caught in this alluring telescopic field of view. Floating in the interstellar sea, the nebula is anchored right and left by two bright stars, Mu and Eta Geminorum, at the foot of the celestial twins. The Jellyfish Nebula itself is right of center, seen as a brighter arcing ridge of emission with dangling tentacles. In fact, this cosmic jellyfish is part of bubble-shaped supernova remnant IC 443, the expanding debris cloud from a massive star that exploded. Light from the explosion first reached planet Earth over 30,000 years ago. Like its cousin in astrophysical waters the Crab Nebula supernova remnant, the Jellyfish Nebula is known to harbor a neutron star, the ultradense remnant of the collapsed stellar core. An emission nebula cataloged as Sharpless 249 fills the field at the upper left. The Jellyfish Nebula is about 5,000 light-years away. At that distance, this image would be about 300 light-years across.

There have been exactly two innovations in web browsers in the last 16 years:

1. "Show Reader Automatically" in 2010;
2. "Hide Distracting Items" in 2024.

Everything else has either been a waste of goddamned time, or actively malicious. Mostly the latter.

Fantastic! #TotallyNormalComputing

Booting #MacOS9 Installer from USB, and without even touching #OpenFirmware. I really like the community for this kind of service!

'Mac OS 9.2.2 "boot kit" for booting your G3/G4 from an USB stick' by that-ben on Macintosh Repository just works out of the box! On a #powerpc #G3 #ibook with USB1.

And it was kinda fast to boot and install too. My #Powerbook got some company now!.
