Huge glowing ball over northern Siberia sparks UFO fears

Russia has been hit by a wave of reports of a giant UFO in the sky last night with spectacular pictures of an enormous glowing ball illuminating northern Siberia. Social media erupted with claims of'aliens arriving' and locals in far flung parts of the country told of'shivers down their spines'. While the source of the light remains unclear, some have suggested that it was the the trace of a rocket launched by the Russian military that caused this extraordinary phenomenon in the night sky. While the source of the light remains unknown, local experts suggest there were two possible reasons for the eerie spectacle in the Siberian night sky. The first was that a vivid display of the Northern Lights - or Aurora Borealis - was underway.
