Sotheby's is auctioning NWA 16788, a 54-pound Martian meteorite, the largest ever found on Earth. Discovered in the Sahara Desert, it's estimated to fetch up to $4 million. Its size and composition, a shergottite formed from Martian volcanic activity, make it exceptionally rare. While some scientists advocate for museum display, others highlight the crucial role of meteorite sales in scientific research. The auction takes place on July 16th.
