This is What's Trending Today...

People on social media have been accusing the American space agency, NASA, of shutting off its live video from the International Space Station. They claim NASA turned off the video stream last week because it showed images of a UFO -- an unidentified flying object.

The video was filmed July 9. A YouTube user named Streepcap1 posted a short part of the International Space Station video. The one-minute 40-second video shows a bright object coming into view. Shortly after the object appears, the video stream experienced technical problems and shut down.

Streetcap1's video has been viewed more than 2.7 million times. It quickly became a trending topic on Twitter and Facebook.

A few days later, NASA answered the questions and theories offered online by people who call themselves "UFO hunters."

NASA spokesman Daniel Huot told the technology magazine CNET that the station "regularly passes out of range," which causes the video signal to disappear.

Huot said the bright object could have been the moon, space debris, or just reflections from the station windows.

And that's What's Trending Today.
