NASA’s Curiosity Mars rover has spotted a set of mysterious ‘stick-like figures’ on the red planet.
In a photo shared to the rover’s Twitter account this week, NASA revealed a look at the unusual formations recently discovered on the face of a Martian rock.
It’s unclear what exactly created the quarter-inch-long ‘stick-figures,’ though the space agency says they could be crystals or minerals left in the gaps where crystals dissolved.
The images were captured during the rover’s ‘working holiday’ at the end of December.
On New Year’s Eve, Curiosity revisited an ‘interesting’ site as part of its activity plan, to get a closer look what NASA says are some ‘very peculiar targets.’
Images captured from orbit with the Mars Reconnaissance Orbiter’s High Resolution Imaging Science Experiment camera reveal the region has some unusual blue hues.
And, it’s also home to a number of darker toned ‘stick’-like features.
‘Meanwhile, back on Mars…I’m checking out these stick-like figures,’ the Curiosity rover’s Twitter account tweeted on Wednesday.
