Just see the NASA's Astronomy Picture Of the Day on July 15 absolutely gorgeous and spotless sun in HD. But without googling it could you guess what is that spot that seems to be hanging there in the top upper left limb of the sun's image?
If you guessed it right could you calculate its' distance from the Earth with the aid of a bit of googling.
A new challenge ! Work it out...
