UFO enthusiasts have said they spotted a fleet of three identical 'giant spaceships' passing the sun, citing an image allegedly captured by NASA's Solar and Heliospheric Observatory (SOHO).

According to alien theorists the particular image with three white spots was taken by SOHO but this is not confirmed yet.

YouTube user, Streetcap1 (via Inquisitr) has uploaded a 56-second picture video that shows three identical UFOs passing the sun.

"I am not going to keep on posting these as I want to do other stuff, however thought this one would be quite hard to dismiss as three CME's hitting the camera lens at the same time, although I could be wrong," said the description of the video.

"This is amazing! Streetcap1 of Youtube has caught a fleet of three big ships following one another in formation passing our sun. Now, when aliens start moving fleets, you know something big is up. This is a very rare occurrence and very important one," wrote Scott C Waring, editor of UFO Daily Sightings

In the past as well, conspiracy theorists have claimed that mysterious objects were spotted on NASA images. 

It was reported a few weeks ago that three alien spaceships were spotted escaping the earth's atmosphere in a video captured from NASA live feed.

The live feed from the International Space Station (ISS) was mysteriously cut by the space agency but not before three UFOs (unidentified flying objects) were caught flying pass the earth's atmosphere into the space, reported Mirror
