Ivan Vagner recently captured something unexplained over the Earth's southern hemisphere.
The intriguing objects, which appeared as a row of five unidentified points of light, were inadvertently picked up while Vagner was filming a time-lapse video of the aurora borealis.
"In the video, you will see something else, not only the aurora," he wrote in a Twitter post. "5 objects appear flying alongside with the same distance."
"What do you think those are? Meteors, satellites or... ?"
Russia's space agency Roscosmos, meanwhile, has reportedly found the footage so intriguing that it has since sent it away for analysis.
"It is too early to make conclusions until our Roscosmos researchers and scientists at the Space Research Institute of the Russian Academy of Sciences tell us what they think," said spokesman Vladimir Ustimenko.
"It was decided to hand over those materials to experts, who will tell us what that was in their opinion."
