Is that what happened... Huh. It did have a very weird story arc. I assumed it was trying to copy "Lost"'s wild success.

The Banana Sketch! Classic! Do you use a yellow banana?? Or a green one??

Ronald "Ray-gun" is fairly well known to us Boomers in the West, even north of the border. He was, after all, well known for his proposed space-based missile defense system, nicknamed "Star Wars". Never heard of Plutonium Blonde though.

Right. So, not a joke at all but a humorous anecdote.

Only partly true. This is astronomer humour:

According to the article: "The images [...] show bright and dark rays stretching out from the crater. The darker streaks are made of surface dust and rocks altered over a long time by solar wind, galactic cosmic rays, and micrometeorite impacts. This weathered material was excavated by the...

NASA has released images of impact. https://science.nasa.gov/solar-system/moon/nasas-lro-images-falcon-9-crater-on-moon-learns-new-details/ Caption: This is an animated before-and-after view of the crater formed after a Falcon 9 upper stage struck the Moon’s surface on Aug. 5, 2026. These...

The dust plume should have fallen back within minutes. Presumably we are seeing the ejecta blanket.

My guess is that subsurface regolith dust is lighter in colour than surface dust - that regolith exposed to the elements for millions of years darkens for some reason. Also, keep in mind that we are not necessarily seeing a difference in colour value - it could be more an issue of reflectivity...

Maybe he was just skeptical about it being funny! 😁

Just imagine the poor guy on the other end of that... "Your call is important to us. You are 13,437th in line. For your listening pleasure, here is Dan Emmett's 'Dixie' on today's Top Hits..."

Whose response is a chatbot. (Not that I have any reason to doubt the figures, except on general principle.)

I suspect that the well-definedness of a boundary has more to do with the strength of the gradient than its physical granularity. A thermocline of 10 degrees F will be a much better reflector than a thermocline of 3 degrees F. The variance of the surface, by cm or m, will affect the clarity of...

It seemed more clever in my head.
