A distinct square shape that appears to be much larger than Earth was spotted on two different cameras 25 hours apart on Wednesday.

The first was shot on NASA’s Solar and Heliospheric Observatory (SOHO) cameras EIT 195 and EIT 171.

Eagle-eyed UFO hunters spotted the mystery cube and uploaded it to the web – sparking conspiracy theorists to comment that an unidentified flying object is in orbit in our solar system.
