Full detailed images of the Martian ‘Skull Hill’ have yet to be released, but it’s already causing a buzz online. Experts claim ‘it shouldn’t be there’. But what exactly is it, and why is it there? What moved it there?
NASA’s trusty Perseverance rover has stumbled upon an eerie new landmark on the Red Planet, and it’s got space-watchers doing a double take. Dubbed “Skull Hill”, this strange formation has left scientists scratching their heads – and conspiracy theorists howling at the Martian moon.
The spooky find was snapped on April 11 as the rover rumbled down a ridge named Witch Hazel Hill – already sounding like the setting of a sci-fi space horror flick. But the real drama unfolded in the Jezero Crater, a whopping 28-mile-wide ancient lakebed that’s been the centre of NASA’s Red Planet operations.
Amongst the usual dusty, light-coloured Martian terrain, this black, pockmarked elevation stood out like a sore thumb… or rather, a giant skull in the sand.
“It looks like it doesn’t belong there,” said Margaret Deahn, a PhD researcher at Purdue University who works with the Perseverance team. Deahn revealed that, unlike its dusty surroundings, Skull Hill is darker, more angular, and covered in tiny pits – leading many to believe it might have travelled from somewhere else. But where did it travel from? And more importantly, what created it?
Well, it’s not a meteorite, despite initial hopes from star-gazers. Using the rover’s high-tech laser-powered SuperCam, scientists analysed a nearby rock with a similar composition – and ruled out space metal. It didn’t contain the tell-tale signs of a space rock, such as high levels of iron and nickel. Still, the science is far from settled.
One leading theory suggests that Skull Hill could be “float” – a geological term for rocks that have moved from their place of origin. That means it might have been flung across the Martian surface by an ancient asteroid impact, swept by erosion, or even carried along by flowing water billions of years ago. Another possibility? It could be an igneous rock, formed when lava or magma cooled long ago.
“Luckily for us, the rover has instruments that can measure the chemical composition of rocks on Mars,” Deahn said, hinting that further tests are on the way to finally unearth the skull’s true identity.
Until then, it’s open season for the internet’s finest – from sci-fi fans claiming it’s an alien monument to one cheeky commenter declaring it looked like a battery tray from a 1948 Hudson Commodore.
Whether it’s geology, coincidence, or something stranger still, Skull Hill has added a new wrinkle to Mars’ already mysterious landscape – and a touch of horror in the middle of April. Many are already asking, is it connected in some way to the infamous ‘Martial Square‘?
Stay tuned, Earthlings. The Martian secrets are only just beginning to surface.
