If you’ve been following NASA’s stream of the International Space Station, you may have seen footage of an unexplainable alien creature make its way across space much like a fish would. Somewhat translucent, the spotted creature could be more evidence of life alien life.

Unsurprisingly, NASA has remained mum on the subject. The space organization has no qualms about reporting alien life when it’s in bacterial form, according to Fox, either on a meteorite or on the planet Mars, but remains rather secretive when bolder discoveries are made. Could it be because they’re hiding something from the public?

The footage was recorded from NASA’s live stream of the station, and though it can’t possibly be a sea creature because of the lack of water, it moves much like a catfish or other low-dwelling aquatic creature would. In various takes of the video, the critter can clearly be seen making its way from the lower-left of the screen, past some of the arms of the International Space Station, before NASA disrupts the transmission.

UFO enthusiasts might remember that earlier this year, NASA pulled photos from its archive that showed another alien anomaly close to Earth’s atmosphere. Those, too, were easily distinguishable visual evidence of strange phenomenon. But NASA waved them off as only being photographs of “space debris.” Though one might ask why someone like NASA would have to take high-res photos of simple space debris.

With more evidence of alien life forms floating near our atmosphere, we need to ask ourselves: what exactly is NASA trying to hide?
