A meteorite, known as NWA 16788, has been sold for $4.3 million at a Sotheby’s auction in New York. This 54-pound specimen is the largest piece of Mars ever found on Earth. Discovered in the Agadez region of Niger in November 2023, it is around 70% larger than the next biggest Martian meteorite and one of only about 400 known to exist. Experts describe it as a monumental find that connects humanity to the mysteries of Mars, although some scientists express concern over its private ownership instead of public display for research and education.

"It belongs in a museum, where it can be studied and enjoyed by the public at large."

Steve Brusatte emphasizes the need for public access to significant scientific discoveries.

"If there was no market for searching, collecting and selling meteorites, we would not have nearly as many in our collections."

The sale of NWA 16788 highlights an ongoing tension in the world of meteorite collecting. While some experts appreciate the funding it generates for science, others worry that significant pieces of our celestial history could end up hidden away from public view.
