From houses on Mars to UFOs on Earth, conspiracy theorists regularly claim to spot bizarre options hidden throughout the Solar System.
Now, one conspiracy theorist claims he has ‘100% proof’ of aliens on Mercury.
Scott C. Waring, who runs UFO Sightings Daily, posted photos of what he claims is an ‘alien structure’ in an image of Mercury, taken by NASA.
On his website, Mr Waring said: “No-one can hide the truth 100%…and here is the proof of that.
“I have discovered a long black structure in a crater on planet Mercury.
“This structure is non reflective black…stealth black probably so it wont reflect radar and so it wont stand out.”
Mr Waring claims that the structure has been built by aliens as a means to hide from other alien species.
