Curiosity rover has taken a picture of a strange Martian structure that one expert has dubbed the ‘most bizarre’ she’s ever seen.
Images snapped by the car-sized robot appear to show spikes protruding from a rock lying at the base of the 96 mile-long (154 km) Gale Crater.
They were taken using Curiosity’s mast camera and ChemCam on Martian day Sol 3786, or April 1, and have sparked speculation online as to what they may depict.
Some have compared the structure to a fish bone or branch of a fir tree, and said it would be ‘difficult for it to be a natural rock formation’ here on Earth.
Curiosity has been roaming the Gale Crater since August 2012 as part of NASA’s Mars Science Laboratory (MSL) mission.
