Pluto's mysterious mountains could be ice-spewing volcanoes, scientists say


Scientists have discovered what appear to be ice-spewing volcanoes on the surface of Pluto, raising questions about how the tiny, distant world has been so geologically active, according to research.

 The findings, released at an American Astronomical Society meeting in National Harbor, Maryland, paint a far more complicated picture of Pluto and its moons than scientists imagined.

“The Pluto system is baffling us,” planetary scientist Alan Stern, with the Southwest Research Institute in Boulder, Colorado, told reporters during a webcast news conference.

Stern heads the team working on Nasa’s New Horizons spacecraft, which made an unprecedented pass by Pluto on 14 July.

Pictures and measurements taken during the encounter are still being transmitted back to Earth.
