Strange ‘leopard spots’ in a Mars rock could be the strongest hint of life yet

NASA’s Perseverance rover has delivered its most compelling clue yet in the search for life on Mars. A rock sample called “Sapphire Canyon,” taken from the Bright Angel formation in Jezero Crater, shows unusual mineral patterns known as “leopard spots” that may have formed through microbial activity. While non-biological processes could also explain the find, scientists say the chemical fingerprints look strikingly similar to those left behind by microbes on Earth.
