A mysterious ice ball has appeared in Milovice forest in the Czech Republic, with some reports suggesting it could be an 'alien' object.
The giant hailstone measures an impressive 2m in diameter, according to the Examiner, and a witness was able to take a video of the spectacle to pop up on YouTube.
Judging by the shakiness of the film, the witness presumably believes it really could be some form of UFO, a view seemingly supported by the news provider, which received a tip-off about it from the UFO Global Reporting Center.
The as-yet-unidentified block of ice seems to be lying in the middle of a dirt track or pathway in the forest and it has horizontal and vertical lines scratched into it - making it resemble somewhat of an igloo.
Perhaps the biggest mystery, aside from where it hails from, is that there are no signs of ice or snow elsewhere in the forest, which some would probably say gives credence to the idea it really did come from outer space.
Just last month, a video posted on YouTube appeared to show an unidentified flying object high up in the sky above London.
A person near the BBC building in west London filmed the phenomenon and posted the video on YouTube, claiming it showed an alien mother ship and its fleet circling over the capital.metro.co.uk
