If you don't get things for free then you have to pay for them. The government either taxes us or doesn't provide services we rely on. Ever since Boris and Rishi splashed the cash in Covid, we have needed to balance the books. www.bbc.co.uk/news/article...

Aurora color guide! What creates the different shades?
Different atoms getting "excited" at different altitudes
The bright reds are a sign of a particularly intense event

Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

My only objection is it should be Celsius 233 for the literal translation. Kudos to the publishers though.
The first (1955) Danish edition of Ray Bradbury’s FAHRENHEIT 451. Later editions did not convert the title, so this is the only SI-compatible edition! 🎢

My favourite region on the #moon, Mare Imbrum, with adjacent craters Sinus Iridum, Plato and Copernicus.
In this moon phase, special tectonic features, so-called wrinkles are visible on the floor of Mare Imbrum, inter alia Dorsum Heim and Dorsum Zirkel
