Switzerland

Tuesday, 18 June 2013, lake Zurich in Switzerland appeared a strange circle of black smoke. Scientists are still not able to clearly explain the origin of this UFO.

When there is a dark ring, it looked like a tiny cloud with the assumed 10 meters diameter. Then little by little it has grown quickly to 50 meters. Throughout its path it has retained its shape, although its outlines have gradually improved. At some moment it suddenly disappeared.

Swiss scientists believe that this may be a new kind of fireworks launched directly over lake Zurich. For others it could come from a special installation to prevent the formation of hail during a storm. Still others suspect that global warming is the cause of this mystery of our time.

Original news

Le mardi 18 juin 2013, un étrange cercle de fumée noire est apparu juste au-dessus du lac de Zurich,  en Suisse. L’OVNI est bel et bien authentique et les scientifiques ne parviennent toujours pas à expliquer clairement son origine …

Lorsque que cet anneau sombre a fait son apparition, il ne ressemblait qu’à un minuscule nuage d’un diamètre estimé à 10 mètres. Puis, petit à petit, il a grandi rapidement jusqu’à atteindre 50 mètres d’envergure. Tout au long de son parcours, il a conservé sa forme sphérique bien que ses contours se soient progressivement affinés. Alors que sa taille ne cessait de croître, il a soudainement disparu sans qu’on en comprenne la raison.

Des scientifiques suisses pensent qu’il pourrait s’agir d’un nouveau genre de feu d’artificeslancé juste au-dessus du lac de Zurich. Pour d’autres, il pourrait tirer son origine d’un canon anti-grêle,  servant à éviter que de la grêle se forme lors d’un orage. D’autres soupçonnent le réchauffement climatique d’être responsable de ce mystère des temps modernes.

Ce qui est le plus étrange dans cette affaire est que cet anneau ne s’est jamais disloqué ni rompu ; il s’est juste évaporé. Hélas, personne ne semble avoir ce nuage surnaturel se former. Et, de ce fait, il parait certains qu’il conservera son mystère encore quelques temps …
