There are a lot of conspiracy theories claiming that UFO and aliens exist. Some are even suggesting that NASA is withholding information about UFO's and that NASA cut off their live feed when an unidentified object suddenly appears on screen, which makes the conspiracy theorists believe that the agency is hiding something. But a recent ISS live feed went viral when a said UFO fireball was spotted lurking behind the ISS.

SecureTeam10 posted the video on Youtube. The video is an enhanced version and part of the live feed by the Internation Space Station (ISS). From the video, a fireball lit up behind the ISS, flaring several times before it disappeared. The Youtube page's administrator said that the UFO is unlikely to be an asteroid or meteor because the fireball behaved differently.

"When you look at this thing up close, it comes directly up out of nowhere, out of the darkness of space," said Tyler Glockner of SecureTeam10 said in the video. Glockner added that he enhanced a video emailed to him from someone who is closely monitoring the ISS live feed.

Glockner proceeded to enlarge the video showing the fireball up close. And from the enhanced footage, it can be seen that the UFO is changing its color from yellowish to red to blue. It appeared out of nowhere, and after it flickered and changed its color, the UFO disappeared again.

Because of this video, UFO hunters claim to have spotted another UFO, according to the Daily Mail.

But NASA thinks that this phenomenon can be explained. It could just be a simple case of solar flares reflected through space.

"Reflections on the station's windows, lights from the spacecraft structure itself or lights from Earth commonly appear as artifacts in photos and videos from the orbiting laboratory, just as reflections often appear in pictures taken through windows here on Earth," said a NASA official in an interview with TechTimes.

The video was viewed more than 400,000 times, but the comments from viewers are divided. Some say it could just be a meteorite or maybe even some sort of space debris

NASA further added that seeing these type of fireballs in the sky is not uncommon because of a number of celestial bodies floating in space.
