TIRED : asking a human expert to identify your unknown rock.
WIRED : asking AI to identify a blurry photo of your rock and then uncritically accepting the results and telling everyone you have a meteorite because Google Lens said so.
This is happening a lot lately in the meteorite and rock collecting world.
TL;DR : AI is terrible at identifying rocks, fossils, and meteorites.
Forget the burning dystopian world for a moment and admire this meteorite from the asteroid belt that landed in my mailbox today. 
Unclassified stony chondrite meteorite. Approx. 75mm in diameter and 213 grams.
Recovered from the Moroccan Sahara and now in the Galactic Stone and Ironworks collection.
Look at the brecciation in this unclassified stony chondrite meteorite. It resembles a Saharan version of Peekskill.
Fresh black fusion crust, copious metal, chondrules, brecciation, this stone has everything you want in a space rock hand specimen.
Approx. 50mm diameter and 85 grams.
In the Galactic Stone and Ironworks collection.
Got a sweet new meteorite yesterday.
It's an unclassified chondrite recovered out of the Moroccan Sahara.
It is a probable type-3 with fresh-ish fusion crust and a polished window showing the chondrule-filled interior.
It measures approx. 75mm in length and weighs 191 grams.
(19 Apr) A Meteorite From Alaska Challenges Theory of How Earth Got Its Water
Scientists speculate that asteroids colliding with Earth delivered water—an essential building block of life—but new research suggests the planet didn't need the delivery.

Meteorite Market Trends. 
This will be an ongoing mega-thread that will be updated regularly.
If you have an interest in collecting #meteorites, please bookmark this thread for future reference.
This idea was inspired by my original meteorite mentor, Michael Blood. Michael penned a similar monthly column for Meteorite Magazine back in the aughts, and I hope to continue the tradition of offering regular insights on trends in the meteorite collecting community.
Unclassified stony chondrite #meteorite recovered from the Saharan Desert in Morocco.
This small stone is about the size of a walnut and has a polished window showing the interior matrix.
From the Galactic Stone & Ironworks collection of #meteorites.

#Chondrule lovers take a peek. 
NWA 2137, an unequilibrated LL3.7 chondrite #meteorite that has a dark inclusion and a ton of chondrules of all types.
This full slice (23.5g) with fusion crust resides in the Galactic Stone and Ironworks collection.

The dagger buried with Tutankhamun is not of this world.
Its blade is made from meteorite iron.

Pretty darn amazing.
“Who knows how many ancient craters lay undiscovered in the ancient cores of other continents? Finding and studying them will transform our understanding of the early Earth and the role of giant impacts, not only in the formation of the landmasses on which we all live, but in the origins of life itself.”

A report published today is outlining the discovery that the oldest meteorite impact happened in Australia some 3.5 billion years ago. This makes it the oldest known hit by over a billion years. It also confirms a theory that geologists had about the formation of Pilbara.
A time-lapse of a few nights ago taken by the #meteor camera I have installed on the roof of my institute. Almost every clear night has been full of #aurora the last few weeks 
The goal is to install 10-14 of these system across northern #sweden and start catching much more meteors with determined orbits (and ones that were also observed by other instruments) and possibly find #meteorites!
(And as a nice side-effect I get lots of cool videos of aurora and polar stratospheric clouds too)
