Nasa's Messenger spacecraft has sent back images which scientists say shows Mercury's most recent volcanic activity.
Dr David Rothery, an Earth scientist from the UK's Open University said "We want to know what has kept Mercury going; it's clearly a much more dynamic planet that we expected."

Images captured by Messenger have revlealed surprising details about the planet



This indicates that rather than being a tiny, long-dead planet, as scientists had assumed, Mercury was volcanically active for much of its "life". The researchers say it also sheds light on how other planets in our Solar System evolved.



Dr Prockter said: "This volcano is about two billion years younger than we would have expected. And it's possible that when Messenger gets into orbit, we'll find younger areas of volcanism.

IMpressive pictures of mercury! very indeed. growing up as a teen in the late 80's and a very serious amateur astronomer, the only photos of mercury were from the 70's still., mariner 9 spacecraft.
however, i fail too see any volcano. The images, show impact basins, just like our moon has, the dark patch areas. Those were form huge impacts that caused lava to fill in, hence forth creating those dark areas. the same thing is in the pics of mercury thier. thiers no dome or mountain feature. a volcano starts as a hole in the ground basically and grows into a moutain like feature.
