Methane gas hints at life on Mars, says NASA

NASA scientists have discovered surprisingly high amounts of methane gas on Mars that could indicate life on the Red Planet.

The space agency’s Curiosity rover made the discovery during a routine mission, according to the New York Times.

It had previously been suggested the gas came from the rover itself, though this theory was rejected by NASA.

However Thomas Zurbuchen, of NASA’s Science Mission Directorate, advised caution over the discovery.

He tweeted: ‘While increased methane levels measured by Mars Curiosity are exciting, as possible indicators for life, it’s important to remember this is an early science result.

‘To maintain scientific integrity, the science team will continue to analyse the data before confirming results.’

In a statement, NASA described the methane detection as an ‘early science result’.

A spokesman added: ‘To maintain scientific integrity, the project science team will continue to analyse the data before confirming results.’
