2 silly and goofy dr who episodes to start off season can't wait for the next episode to be an experience so emotionally harrowing it makes me age 10 years
Spectacular eruption of the Etna volcano in which the column of smoke reached about 15km above sea level. Photo taken from the town of Cesarò, in the Nebrodi mountains about 30km away from the volcano.
