I was just talking about extraterrestrials with you in yesterday's blog,  when out of the blue came the news about how a resident of Hong Kong chanced to take a picture of a black,  circular object.   A UFO club believes that there is a 60% chance that the object is a spaceship.   However,  some experts claim that it is the silhouette of a butterfly.   So,  is it a spaceship or a butterfly?   Whether it is real or a misunderstanding,  this type of news always really fascinates me.
