Polish resident Adam Borucki made a highly unusual discovery in his backyard after waking up — the purported remains of a second stage of a SpaceX Falcon 9 rocket. As the UK tabloid The Daily Mail reports,

The pyrotechnics were in fact caused by a Space X Falcon 9 rocket re-entering the Earth's atmosphere. There are reports of sightings in Denmark, Sweden and England. Pieces of the rocket then crashed into Poland and, experts say, may also have landed in Ukraine.

A SpaceX rocket stage fell to Earth early Wednesday morning (Feb. 19), blazing a trail of fire through European skies.
