Scientists have admitted that a crater on the surface of Mars may have been formed by the crash of an alien spacecraft.
Photos of the scarred rock even appear to show wheels, an axle, and other debris.
Experts said a “fragment of an alien or terrestrial spacecraft cannot be ruled out with absolute certainty.”
The bizarre peaks and bumps can be seen in images taken by NASA’s Curiosity rover as it explored the red planet’s 96-mile-long Gale crater in April.
At the time, the space agency’s astrobiologist, Dr. Nathalie Cabrol called it “the most bizarre rock” she’s seen in 20 years of Mars exploration.
Now, new research concludes the formations may be “sand spikes” such as those formed when Earth’s strong earthquakes occur.
The authors, including Aston University’s Prof Richard Armstrong, said the objects are unlikely to have come from the 10 man-made spacecraft that crashed or disappeared on Mars.
Prof. Armstrong added: “One can only speculate about extraterrestrial origins.
“Images of Mars often show strange formations that ‘look’ like familiar objects.”
