The National Aeronautics and Space Administration's (NASA) Curiosity rover has explored Gale Crater on Mars in detail. Now, the rover has provided some evidence regarding a massive lake that might have existed on the red planet in the part. According to data gathered by Curiosity, the planet was having much higher amount of water than previously thought. Scientists said that a 96-mile-wide crater existed at the site of Gale Crater in the past.
The crater was believed to be formed because of build-up of sediment over an incredibly long period of time. A large mountain was once located at the heart of the crater. According to the scientists, there are possibilities that there was life on the Red Planet when the lake existed.
