Sharpless 249 and the Jellyfish Nebula
Image Credit & Copyright: Katelyn Beecroft

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.

Despite the issues with the companies involved, maybe there is something here that Fediverse platforms can benefit from. Whether it is using the tools directly, or using it for ideas when building something better.

From the site:

Coop provides content review tools and includes the ability to route reviews to the experts, show relevant information for a comprehensive review, and take action. The platform includes built-in integration with the National Center for Missing & Exploited Children’s (NCMEC) API for mandatory reporting of child sexual abuse material (CSAM), ensuring compliance with relevant regulations.

Osprey is an open-source investigation and incident response tool that allows safety teams to understand what is happening on their platforms and take actions at scale. Osprey’s lightweight, user-friendly design makes it especially valuable for platforms of all sizes, from grassroots communities to established platforms that need powerful tools without enterprise-scale infrastructure.

Bluesky is taking from it already:

"We're excited for the implementation and release of Osprey," said Aaron Rodericks, Head of Trust and Safety at Bluesky, which plans to adopt Osprey. "This represents exactly the kind of open collaboration needed to democratize safety tools. By implementing Osprey, we're helping prove that effective safety infrastructure can work for platforms of all sizes, not just those with massive resources."

I just finished Oliver Sacks’ excellent Everything in Its Place. In it, he mentioned as an aside that the Ginkgo biloba tree is hundreds of millions of years old, and its phenotype has been practically frozen since then – a living fossil.

Of course, this is the same tree that grows ぎんなん (Ginkgo nuts), an East Asian delicacy found in many dishes, 茶碗蒸し (Chawanmushi) for example.

Ginkgo has been around so long, it predates the dinosaurs! And we still eat it! How cool is that. This got me thinking – what are the oldest foods we consume today?

Criteria:

• Must be edible by humans
• Must be morphologically unchanged since its fossil age

When officers entered the school on Tuesday afternoon, they found six victims deceased, RCMP confirmed.

An individual believed to be the shooter was also found deceased with what appears to be a self‑inflicted injury.

Two victims have been airlifted to the hospital with serious or life‑threatening injuries. A third victim died while being transported to hospital. Approximately 25 others are being assessed and triaged at the local medical centre for non‑life‑threatening injuries.

The active shooter alert was lifted at 5:46 p.m. PT.
