Somewhat like a fruitcake that has fallen off a shelf into some flour and cracked

The Hypatia Stone analized.

Some exiting and unexpected news from the University of Johannesburg.

Quote:
Analyses on a small pebble found in south-west Egypt cast significant questions on a widely-held view about the primitive pre-solar dust cloud which our Sun, Earth and other planets were formed from.
Quote:
"The aluminum occurs in pure metallic form, on its own, not in a chemical compound with other elements. As a comparison, gold occurs in nuggets, but aluminum never does. This occurrence is extremely rare on Earth and the rest of our solar system, as far as is known in science," says Belyanin.

"We also found silver iodine phosphide and moissanite (silicon carbide) grains, again in highly unexpected forms. The grains are the first documented to be found in situ (as is) without having to first dissolve the surrounding rock with acid," adds Belyanin. "There are also grains of a compound consisting of mainly nickel and phosphorus, with very little iron; a mineral composition never observed before on Earth or in meteorites," he adds.

Extraterrestrial alien litterbugs. Tossed it right out the window during a flyby.

Sorry, I couldn't resist using that for the thread title.
It's not exactly obvious what it's about.

It has metallic aluminum. It was probably a beer can.

Given the nature of the galaxy and its rotation and the clouds around stars, I imagine they are interacting.
So it may be from another proto planetary disk or from a supernova remnant explosion

Or might have been made during a collision of two flying saucers. Evrybosy knows the Farengi can't drive.

While there might be some mystery to the OP object, it in no way compares to Fruitcake.
Nobody knows where Fruitcake comes from.

We just saw an interstellar asteroid pass through, and we know there are likely many more. So why does finding a bit of one raise any questions about the protoplanetary disk we formed from?

Fake news. Aluminium always comes as a compound. The element would react strongly with oxygen. If it was real then they would have started a huge search for more fragments.

Though on the other hand how do we know that this is not from the solar system? It could be from a rare type of rock found in space.

It is believed to be part of the nucleus of a comet, not an asteroid.
I don't believe any other fragments of a comet's nucleus have ever been found before.

Well, it is real and not of terrestrial origin, what do you mean? No one disputes that it's a weird rock from outer space.

26 mya something struck the Libyan desert, creating the famous Libyan glass strewnfield. People have been making tools and jewelry from it for a long time.
The stone was found smack in the middle of this strewnfield and is believed to be part of the nucleus of a comet, the one that struck there.

So it might be part of a comet and looks different to what was expected, that's pretty interesting.

It appears to be genuine. You need to read all of the article to understand it.

Interesting. One would think there might be more fragments in the area.

Too right. I assumed it was another Trump thread.

Well, it has been 26 million years, a lot can happen in that time.
