“Gray matter” has been discovered on Mars in the past, and it appears that it wasn’t just a single occurrence. Back in 2013, NASA scientists spotted some weird formations that couldn’t be explained. “This strange-looking Mars surface might be related to flow of the ice, but we still don’t have a definite explanation for this mystery,” declared scientists back then.
This time, new mysterious textures were discovered on Mars. The terrain has a strange aspect that looks very similar to brain folds, which is why it has been named “brain terrain.” The images were captured by the High-Resolution Imaging Science Experiment (HiRISE) instrument on the Mars Reconnaissance Orbiter (MRO) spacecraft. You can find a high-resolution version of the images at this link.
Underground water might cause the appearance of the mysterious Mars surface with brain-like texture
It is hard to tell what makes the terrain look like that, and scientists are, in fact, still puzzled by it. At the moment it is speculated that the water below the surface is the reason why this mysterious Mars surface looks like that. The texture could be created when the water buried down there transforms from a solid to a gas.
More than that, NASA researchers believe that the formation of the brain terrains could be an active process. However, the images don’t show any significant changes. NASA’s Mars Reconnaissance Orbiter has been orbiting the Red Planet since 2006, and its goal is to collect data about the planet, especially when it comes to its surface and the water there.
That is not the first time weird surfaces are discovered on Mars, and there have been many strange images in the past years. For instance, one picture captured something that looked like a thigh bone. Other things, such as a crater that resembles Pac-Man have been discovered there.
