A scheduled launch of Russia’s Soyuz rocket with a satellite aboard turned into quite an event in Russia after pictures of it heading into space baffled the whole country.

People across Russia took to social media to post dazzling pictures and videos featuring a mysterious object flying over them on Sunday night. Searching for an explanation, some said it could have been a UFO.

However,  it turned out to be a Russian Soyuz 2.1-b rocket, which was launched at 12:46am Moscow time from the Plesetsk test launch site. Several hours later, the carrier rocket’s Fregat booster put the Glonass-M navigational satellite into orbit. The satellite will join the group of Russia’s Global Navigation Satellite System (GLONASS), which currently has a total of 25 objects.

 The Soyuz rocket flyover was seen throughout western Russia, from Arkhangelsk Region to Moscow.
