The recent auction of a Martian meteorite -- for a record-grabbing $5.3 million at Sotheby's New York -- has sparked questions over its provenance and renewed debate over who gets to claim rocks fallen from the heavens.
The hefty 54-pound (25-kilogram) stone is the largest Martian meteorite ever discovered on Earth, according to its Sotheby's listing, and was found in November 2023 in the vast Saharan desert in Niger.
