NASA has rubbished claims about the 'alien pasta' found on Mars

The US space agency believed that the tangled web of "spaghetti" could be proof of alien life but has now concluded that the weed-like spiral was a piece of netting from where the Mars rover was descending.

It said: "This particular piece of netting appears to have undergone significant unravelling/shredding, suggesting that it was subjected to strong forces."

The 'spaghetti' photo was first seen last month and sparked a wild variety of theories about signs of life on the red planet.

NASA originally said of the unique sighting: "An object that appeared as a ball of knotted, stringlike material blew underneath the front of the rover.

"Before the string could be imaged by the high-resolution Mastcam-Z cameras, the string was blown away by the wind."
