For whatever reason, Mars just seems to have a hold on the human imagination. For centuries, artists and writers have depicted the red planet as a bizarre alien world full of strange creatures beyond our wildest imaginations. Perhaps the most famous example of our collective fascination with Mars is H.G. Wells’ 1898 novel The War of the Worlds, in which hostile Martians leave their dying planet behind to come down and steal ours - by eradicating humanity in the process, naturally.
Even though we have successfully landed several rovers on the surface of the red planet and catalogued its surface with orbital satellites, the speculations and fanciful imaginings about what wonders lie for us on Mars continue to this day. In most recent perhaps-speculative Mars news, some internet alien hunters have released what they call “proof” of a past intelligent civilization on Mars.
The recent buzz began when YouTuber Mundodesconocido published a Spanish-language video alleging that three tower-like structures seen in photographs are a set of alien megastructures each over a mile high. Mundodesconocido spotted the structures in the the Terra Meridiani region of Mars while poring over images collected by Google Mars. The images were originally taken by NASA during the Mars Global Surveyor and Mars Odyssey missions.
Aside from Google Mars, the raw images which depict the alleged "alien megatowers" are published by Malin Space Systems can be seen on their website. Clearly, if the photos can be considered accurate, there are indeed three very similarly-shaped structures found in this particular region of the Marian landscape; whether or not they are of alien origin, however, remains a mystery. The “towers” could simply be naturally-occurring geological formations. Satellite images are notoriously difficult to use as proof for claims that structures seen in them might be artificially-constructed.
Naturally, many of the usual alien-hunting sources have declared this to be definitive proof of alien life on Mars. With similar claims being tossed about every time a strange rock is found on Mars, however, it can be difficult to take these types of discoveries seriously.
