Yamato 000593 (or Y000593) is the second largest meteorite from Mars found on Earth. Studies suggest the Martian meteorite was formed about 1.3 billion years ago from a lava flow on Mars. An impact occurred on Mars about 12 million years ago and ejected the meteorite from the Martian surface into space. The meteorite landed on Earth in Antarctica about 50,000 years ago. The mass of the meteorite is and has been found to contain evidence of past water alteration.〔〔〔 At a microscopic level, spheres are found in the meteorite that are rich in carbon compared to surrounding areas that lack such spheres. The carbon-rich spheres and the observed micro-tunnels may have been formed by biotic activity, according to NASA scientists.〔〔〔 ==Discovery and naming== The 41st Japanese Antarctic Research Expedition (JARE) found the meteorite in late December 2000 on the Yamato Glacier at the Queen Fabiola Mountains, Antarctica.〔
