China's Yutu 2 lunar rover spotted a mysterious object on the horizon as it traversed the far side of the moon, according to reports.
A diary entry published by Our Space said the rover took the image in November. Our Space is affiliated with the China National Space Administration (CNSA), according to website Space.com.
Andrew Jones, a journalist who follows China's space programme, tweeted the cube-shaped image was around 80m away from the rover in the Von Kármán crater.
"Referred to as "神秘小屋" ("mystery house"), the next 2-3 lunar days will be spent getting closer to check it out," he wrote.
He also confirmed it's unlikely to be of extra-terrestrial origin.
"So yeah, it's not an obelisk or aliens, but certainly something to check out, and hard to discern much from the image," he continued.
"But large boulders are sometimes excavated by impacts."
Of course the image is cause for internet users having fun. Many are replying to a tweet from 'Latest in space' speculating what exactly the object might be.
One suggested it could be a Nissan Cube, while another thought Elon Musk was getting prepared for Mars by installing a Tesla charging station on the moon.
Others invoked games like Fortnite and Super Mario, which use cube-shaped objects.
Finally, one suggested a close-up would reveal the image was a new McDonald's restaurant.
Yutu2 landed on the moon at the beginning of 2019 and has been making its way across the 186km-wide Von Kármán crater since then.
It was the first rover to land on the far side of the moon and did so as part of the CNSA's Chang'e 4 mission.
