Curiosity rover found a big hint pointing to life on Mars



The NASA Curiosity rover made a remarkable discovery this week that may hint at signs of life on Mars

The surprising development, reported by The New York Times, brings legitimacy to the long-held notion that aliens may [[196590010] According to a measurement taken on Wednesday by NASA's Curiosity rover, scientists have discovered high amounts of methane in the air on Mars – indicating microbes could survive on the planet. As the Times noted, methane is typically just produced by living things

This image from Curiosity's Mastcam shows inclined beds of sandstone interpreted as deposits of small deltas fed by rivers flowing down from the Gale Crater rim and building into a lake where Mount Sharp is now. It was taken March 13, 2014, just north of the Kimberley Waypoint.

This March 25, 2014, view from the Mastcam on NASA's Curiosity Mars rover looks southward at the Kimberley waypoint. In the foreground, multiple sandstone beds show a systematic inclination to the south suggesting the progressive build-up of delta sediments in that direction (toward Mount Sharp).

This image shows an example of a thin-laminated , evenly stratified rock type that occurs in the "Pahrump Hills" outcrop at the base of Mount Sharp on Mars. The Mastcam on NASA's Curiosity Mars rover acquired this view on Oct. 28, 2014.

This is not the first time that scientists have found methane on Mars: In 2004, scientists reported the discovery of methane in the air, following three years of observations. "We are 99 percent confident," Dr. Michael Mumma, senior scientist at NASA's Goddard Space Flight Center, told The Times that news. "

However, in 2013, new measurements from the Curiosity rover found that the atmosphere contained very little or no methane, reducing the prospect of life on the planet. Study author Christopher Webster, director of the NDEA's Jet Propulsion Laboratory, described these results as "disappointing for many," in an interview with Business Insider in 2013.

, the project scientist for the mission, wrote to his team that "given this surprising result, we've reorganized the weekend to run a follow-up experiment," with the results of those observations expected on Monday
