Russian astronaut Ivan Vagner was hoping to capture something spectacular on camera from his current home aboard the International Space Station — the Aurora Borealis passing over the Antarctic.

However, his timelapse footage, tweeted on August 19, captured something even more unusual; a group of five unidentified flying objects (UFOs). “At 9-12 seconds, 5 objects appear flying alongside with the same distance,” Vagner wrote. “What do you think those are? Meteors, satellites or…?”

Shortly after this, they split up just before the arrival of Sardan Lights. The two space ships reappeared from different places. Now video of Ivan Wagner has been sent to Russian scientists for investigation.
