It's another giant leap for mankind, as potential proof of life on Mars could change everything you thought you knew about the Red Planet.
NASA's Perseverance rover has been exploring the Jezero crater as part of the Mars 2020 mission since February 2021, and in one recent discovery, it's hinted that life really does find a way.
In July 2024, the Perseverance rover discovered a vein-filled rock that's been nicknamed 'Cheyava Falls'.
Measuring 3.2 feet long and 2 feet wide, Cheyava Falls caught NASA's attention due to a series of 'leopard spots'.

Although it might not sound like much, these colored spots can be an indication of life.
Perseverance's instruments unearthed organic compounds inside the rock, which NASA notes are essential for known life.
The space agency excitingly says that Cheyava Falls "possesses qualities that fit the definition of a possible indicator of ancient life."

The discoloration could be caused by chemical reactions and structures that are typically formed by life, suggesting that the rock was exposed to some form of microbial life many moons ago. It's far from proof that bulb-headed Martians once walked the planet's surface, but instead, the implication is that bacterial life once flourished on Mars.
These tiny leopard spots contain iron and phosphate, which are elements associated with microbial life. NASA astrobiologists use the seven-step scale known as the Confidence of Life Detection (CoLD), placing Cheyava Falls on Step One, "Detect possible signal."
The was discovered in an area called Neretva Vallis, thought to be an ancient river valley that once had running water eons ago.
Before getting too excited, NASA says it's looking into other options for what could've given the rock its unique appearance instead of just jumping to the idea that aliens might've once bathed in a river here.

Discussing the groundbreaking find, NASA associate administrator for Science Mission Directorate Nicola Fox said: "We have designed the route for Perseverance to ensure that it goes to areas with the potential for interesting scientific samples.
"This trip through the Neretva Vallis riverbed paid off as we found something we've never seen before, which will give our scientists so much to study."
This was echoed by Ken Farley, a project scientist behind Perseverance, saying: "Cheyava Falls is the most puzzling, complex, and potentially important rock yet investigated by Perseverance.

"On the one hand, we have our first compelling detection of organic material, distinctive colorful spots indicative of chemical reactions that microbial life could use as an energy source, and clear evidence that water — necessary for life — once passed through the rock.
"On the other hand, we have been unable to determine exactly how the rock formed and to what extent nearby rocks may have heated Cheyava Falls and contributed to these features."
NASA still hasn't concluded what the rock means, although life on Mars theorists are confident that we're one step closer to unlocking the mysteries of the planet's past and a potential future that could support the human race.
