Last month people in Manitoulin Island, Canada, were treated to a stunning sunset in which rings of light appeared to encapsulate the sun.
Christine McNaughton, a digital strategist, posted photos of the incredible sight on Twitter - and her images have now caught the attention of conspiracy theorists.
Scott. C Waring, who runs ET Database, claims that the rings are caused by a surge of energy over the lake in that area.
On his website, he explained: “Now live atomic bombs have been lost in those lakes, but if this wasn't seen from other areas, then it couldn't be a atomic bomb from WWII era.

“It could however be a massive UFO rising out of the bottom of the great lake. This UFO would have to be driven by a huge amount of energy and would be forced to sit there until after sunset when its safe to fly away under the cloak of darkness.
“It defiantly sounds like evidence of an underwater alien base in that direction on the lake floor.”
However, while Mr Waring is convinced that the rings are a sign of alien life, there’s a pretty simple explanation.

The rings are likely to be sun halos, which are created by thin cirrus clouds.
EarthSky.org explained: “These clouds contain millions of tiny ice crystals.
“The halos you see are caused by both refraction, or splitting of light, and also by reflection, or glints of light from these ice crystals.
“The crystals have to be oriented and positioned just so with respect to your eye, in order for the halo to appear.”
