It is still not known if aliens and UFO (unidentified flying objects) really exist but reports of UFO sightings keep coming in. The latest we heard is that a bright object was spotted flying across the earth at great speed in Nasa's live video feed captured from International Space Station (ISS). <br /> <br />In the video footage captured from the ISS, a bright object is seen flying above the earth at a great speed but the live feed was stopped abruptly before it could cross the horizon. The screen turned blank and a statement appeared: "Please stand by. The High Definition Earth Viewing experiment is either switching cameras, or we are experiencing a temporary loss of signal with the International Space Station." The video has been uploaded on YouTube by ColdPyro. <br /> <br />Now, conspiracy theorists have claimed that Nasa had intentionally cut the live feed to cover up proof of aliens' existence. Some UFO hunters have even described the white speck as a "mysterious spacecraft." <br /> <br />UFO enthusiasts have alleged several times in the past that Nasa intentionally cut live feed from the ISS when mysterious objects appear in the skies. <br /> <br />Interestingly, two black objects were seen flying pass the supermoon at great speed in a video captured last week. UFO enthusiasts have claimed that the mysterious objects were spacecrafts while many viewers said that they could be birds, satellites or even. http://www.ibtimes.co.in/ufo-sightings-2016-nasa-cuts-iss-live-feed-when-bright-object-moved-quickly-across-earth-video-704654
