NASA's Curiosity arrives at Martian ridge formed during 'wet period'

NASA's Curiosity rover has successfully reached a rather intriguing location on Mars, called Gediz Vallis Ridge, which may contain crucial information about the planet's watery past. The rover has captured a stunning 360-degree panoramic view of the ridge, that is theorized to have formed from violent debris flows, that were later eroded by wind into a towering formation. Interestingly, this event took place about 3 billion years ago during one of the last wet periods on Mars.
