There’s another weird thing on Mars, and Nasa really doesn’t know what it is this time.
You may remember the $2.5 billion Curiosity rover currently drilling rocks on the Red Planet already found strange shiny things and what was labelled a ‘Martian Flower’.
But if anything, this is even weirder.
An image posted by Nasa on 30 January and taken with the right Mastcam on Curiosity shows what appears to be a 0.5cm metal spoke protruding out of a rock.
The strange sight – which looks a bit like a robotic arm – was noticed by imaging editor Elisabetta Bonora from Italy.
Whatever it is looks shiny, casts a shadow on the rock below and looks different to the rock it emerges from.
