The footage uploaded to YouTube has been hailed as proof of a long-running conspiracy theory that there are buildings on the Moon, which could either be occupied by aliens, or be a secret NASA outpost.

Most video or images put forward in the past as proof of the conspiracy theory have shown blurry white objects that many said were just rock formations.

However, the new footage claims to have some of the clearest shots ever of buildings on the Moon.

In the clip, a landing craft approaches the moon’s surface at a slow speed, Dailystar.co.uk reports.

As it does so, the moon’s famous craters come into focus.

But ominously, an L-shaped structure appears to come into shot – sparking wild conspiracy theories of a colony in space.
