The Jewel Box is an open star cluster visible as a faint smudge with the naked eye under dark skies. It is located 6,440 light years away towards the constellation Crux, The Southern Cross. The first person to recognise it as a cluster of individual stars was Nicolas Louis de Lacaille during his visit to Cape Town in 1752. The name of the cluster originates from John Herschel's later observations in the 1830's, also from Cape Town, and his resulting vivid description:
"A most vivid and beautiful cluster, though neither a large nor a rich one, is yet an extremely brilliant and beautiful object when viewed through an instrument of sufficient aperture to show distinctly the very different colour of its constituent stars, which give it the effect of a superb piece of fancy jewellery"
The bright orange star in the centre of the cluster is known as Kappa Crucis. It provides a striking contrast with the rest of the hot blue cluster members. Although the cluster is a mere 14 million years young this star has already reached the red giant phase of its life and will most likely explode in a brilliant supernova within the next few million years.
The cluster has ben photographed by a wide array of professional telescopes, including ESO's VLT and La Silla observatories and the Hubble Space Telescope.

The thing to understand about "age verification" laws is that they are not just for kids
The only way to "stop kids from doing xyz online" using age-gating is to demand a government ID (or invasive biometric face scan) from EVERYONE.
This means associating your gov ID with EVERYTHING YOU DO ONLINE

In the Fight Against Fascism, Libraries Should Be Defended β Not Defunded
Libraries represent the kind of infrastructure progressive leaders must fortify at all costs, especially in this moment.
Libraries are sites of refuge, where curiosity is nurtured, where people find shelter, education, entertainment, job assistance, skill-building programs, and access to resources that would otherwise be out of reach.

End of fossil fuel era inches closer as Cop30 deal agreed after bitter standoff
Wealthy countries agree to triple funds for countries to tackle climate impacts, but deforestation and critical minerals blocked from final deal
After two weeks of #COP30 negotiations, countries agreed to BEGIN DISCUSSIONS on fossil fuel phase out. And as the article says, "they achieved this incremental progress only in the teeth of implacable opposition from oil-producing countries."
THIS is the problem with requiring unanimous decisions.
