ESA astronaut Tim Peake took this image from the International Space Station during his six-month Principia mission. He commented: "I'm guessing there was an impressive storm going on under that cumulonimbus cloud!"
Professional photographer Max Alexander has known Tim Peake from before his launch into space and gave Tim photography tips during his mission. Max comments: "Towering cumulonimbus clouds belie a violent thunderstorm beneath in this stunning photograph. Low raking light casts long shadows, emphasising the form, and giving the photograph a three dimensional quality."
