YouTube user “rob19791”claims he has found proof that NASA is covering up evidence of aliens because the agency’s spacecraft that monitors the Sun went offline after he spotted a “UFO” on its video feed.

On May 5, “rob19791” posted a YouTube video of a mysterious-looking “object” hovering near the sun. The footage was taken from video that the Solar and Heliospheric Observatory beamed back to Earth and streamed online.

But the claims are likely to fall on deaf ears at NASA after two other similar sightings of “alien spaceships” have been debunked with simple explanations.

The video zooms in on a pyramid-shaped object hovering above the sun’s surface.

One day later, NASA shut down the spacecraft’s video feed as it went into “emergency Sun reacquisition mode”.

“This is a cover up to prevent us from seeing these things again. NASA must have seen this video and started making plans to change the way you and I are allowed to view it,” he said in a second video.

“I think this is proof that NASA is covering this up.

“NASA is clearly trying to stop us looking at the sun,” he added.

This is the third time in recent months that believers have pointed out “proof” of UFOs based on supposedly unexplained phenomena on NASA’s space-monitoring equipment.

In December, a man says he found a “cloaked” space ship orbiting Mercury.

March brought the “Death Star”, a planet-size object seen “refueling” at the Sun – similar to rob19791’s triangular discovery.

In March, NASA scientists debunked the Death Star theory by explaining that cameras had simply captured a solar filament – a tunnel of matter extending out from the sun and cooling to form a dark “spot”.

It appears this might be the explanation for the second “UFO”, as well.

While the answer is shorter on conspiracy, it is no less puzzling to scientists.

They still aren’t sure what the filaments are or what caused them to form.
