NASA has found ‘sign of life’ on Mars [Video]

NASA has found traces of a gas on Mars that is produced by living creatures on Earth.

The Curiosity Rover, which has been active on Mars for more than 11 and a half years, managed to detect traces of methane on the Red Planet.

The rover detected the gas coming from Gale Crater. The methane traces appeared at different times of the day and have been fluctuating seasonally, and sometimes spikes to levels 40 times higher than usua

Here on Earth, most of the methane is produced by animals as they digest food. Due to a distinct lack of cows or any other animals on Mars, scientists didn’t expect to find the gas on the planet.

Scientists believe the Mars methane comes from deep underground, encased in solidified salt and only released when temperatures rise on the planet or something breaks the crust, like Curiosity.
