NASA's Curiosity rover captured a coral-shaped rock on Mars, suggesting ancient life signs. The formation likely resulted from mineral-rich water infiltrating rock cracks, which dried and left behind hardened minerals. Wind erosion over billions of years revealed these unique shapes. The rover's mission in Gale Crater aids understanding the transition of Mars from a potentially habitable environment to its current state as a frozen desert. Enthusiastic reactions online reflect the intrigue surrounding potential life evidence on the planet.
The twisted, alien-like formation was sculpted by wind and time, likely formed billions of years ago when water once flowed across the Martian surface.
'Curiosity has found many small features like this one, which formed billions of years ago when liquid water still existed on Mars.'
'Water carried dissolved minerals into rock cracks and later dried, leaving the hardened minerals behind.'
