Looking through images of Mars, Bristol-based amateur astronomer Joe White managed to detect what he described as "a small feminine looking statue head which resembles a carved depiction of a female warrior wearing a helmet similar to some found on Earth from the middle ages," according to Metro.
White, who runs the YouTube channel ArtAlienTV, explained that the bust features what looks like an emblem on its forehead and "some very interesting facial features that look almost Egyptian in artistic style."
"This is one of hundreds of similar artefacts that I have found on Mars in recent years and may go further to show that there was an ancient and artistic civilization on Mars in the past. The question is how long ago?" he said.
Taking photos of the Red Planet is one of the tasks implemented by NASA's Curiosity rover, which has just passed its 2000-solar day mark on the surface of the fourth planet in our solar system. The rover landed on Mars in August 2012 and has been exploring the red planet ever since.
