A newly released study indicates that the hundreds of valleys on the Red Planet, the so-called “ghost dunes,” might hold proof of ancient alien life on Mars. The study, issued in the Journal of Geophysical Research: Planets, revealed that these “ghost dunes” on Mars had been preserved with lava and sediment.
“We know that dunes on Earth can support life, and dunes on Earth are very similar to dunes on Mars. One problem that Mars has that Earth doesn’t is the surface radiation,” explained Mackenzie Day, a planetary geomorphologist from the University of Washington.
According to the researchers, the ancient dunes on Mars might house evidence of alien life, but also give clues on how the winds on the Red Planet behave in the past.
The scientists discovered and explored the “ghost dunes” on Mars thanks to satellite images of the Noctis Labyrinthus and Hellas basin.
“Ghost dunes” on Mars might hold proof of ancient alien life, similarly to those on Earth
Even though these dunes on the Red Planet might seem alien, they are ubiquitous in the Universe. One good example is that of the “ghost dunes” found in eastern Idaho, USA.
Similarly to those on Earth, the ancient dunes on Mars formed in the early history of the planet, more specifically, in the Hesperian period when the climate on Mars shifted from a wet one to a dry and windy one. Therefore, the dunes hold precious data about how the Red Planet had been then.
According to the scientists, “ghost dunes” on the Red Planet might present traces of ancient alien life on Mars, but the chances to be something alive in there as we speak are almost null.
“There is probably nothing living there now. But if there ever was anything on Mars, this is a better place than average to look,” said Mackenzie Day.
