On this day in history, NASA announced that its Curiosity rover found signs that might have pointed to life on Mars. On Dec. 9, 2013, NASA scientists reported that the rover had discovered signs of a water hole that existed around 3.

NASA’s Curiosity Rover Captures Spiderweb-Like Structures on Mars, Sparks Signs of Alien Life NASA's Curiosity Rover recently made an extraordinary discovery on the soils of the planet, one that was deemed to be significant in understanding if life was present on the planet before.

Curiosity has just finished the latest leg of its 12-year Mars mission and will now set out to explore miles of web-like surface features left behind by ancient water on the Red Planet. The zig-zagging rocks could also provide clues about whether Mars once harbored extraterrestrial life.

The Mars rover, built by NASA's Jet Propulsion Laboratory (JPL), has slowly scaled Mount Sharp since 2014. This mountain, officially monikered "Aeolis Mons," was discovered in the 1970s; cut into its alien landscape is the boulder-packed Gediz Vallis channel, which some scientists believe to be an ancient river bed.
