Live on Mars BREAKTHROUGH: Biologist claims & # 39; still has life & # 39; But & # 39; it's hiding & # 39; | Science | News

When looking for locations where foreign life could potentially live, few places fire the imagination like Earth's nearest neighbor – Mars. For centuries people have looked to the sky and wondered what Mars is like for extraterrestrials. Although NASA research has yet to find evidence of foreign life on Mars, it does not necessarily mean the Red Planet is dead, a NASA scientist has announced.

Four billion years ago, the Marian surface was a water world, featuring water-based rivers, lakes and even a deep ocean.

And some astrobiologists believe an ancient Mars was a more conducive cradle of life as early as Earth.

While growing scientific consensus, life on earth could have been sown by Martian asteroids slamming into our planet.

However, Mars lost its habit when the red planet lost its global magnetic field.

This in turn allows deadly emanating from the sun to strip off the once-thick Martian atmosphere.

NASA's Maven Orbitry has shown how this process transforms, though in the cold, dry world we recognize today.

But this planetary evolution doesn't necessarily mean the red planet is now a dead planet.

Michael Finny, co-founder of the Genome Partnership, said: "If Mars had lived nearly 4 billion years ago, Mars still had life.

"Nothing happened on Mars that would grow out of life.

"So, if it was live on Mars, it could have moved around, it could be a bit slow, but it's probably still."

One of the most promising hiding places for finding alien life is beneath the Martian surface.

Although there is a lack of running water on the Martian surface – apart, potentially, occasionally flowing on warmer areas – there is probably plenty of water in buried aquifers.

For example, Mars Express Orbits data suggests a large lake could lure below the end of the planet's south pole.

There is an absence of evidence for life in the Martian air, though US. There. NASA's space agency recently spotted some intriguing clues.

For example, the NASA Mars Curiosity Rover has rolled by two planets of methane within the 96-mile (154-kilometer) gale crater, exploring the six-wild robot since its 2012 touchdown.

The Rover mission also determined that baseline methane concentrations in the air of the gall were cycled seasonally.

More than 90% of Earth's atomic metal is produced by microbes and other organisms, which allow gas to be a signature of modern Martian life.

But other, less exciting explanations could account for this.

Abiotic processes, for example, can also produce methane, such as the reaction of hot water with certain types of rock.

And even if marine methane is biogenic, the creatures that created it could be long dead.

NASA data suggests the red planet methane plums leaked out of the underground, and there is no story how long the gas was trapped down there before making its way to the surface.
