Scientists have found evidence that
tiny, distant Pluto harbors a hidden ocean beneath the frozen surface of its
heart shaped central plain contains as much water as all of Earth’s seas. The finding,
reported on 16 November in two research papers published in the journal Nature,
adds Pluto to growing list of worlds in the solar system beyond Earth believed
to have underground oceans, some of which potentially could be habitats for
life. Pluto’s ocean, which is likely slushy with ice, lies 150 to 200 km
beneath the dwarf planet’s icy surface and is about 100km deep, planetary
scientists said in an interview. With its ocean covered by so much ice, Pluto
is not a prime candidate for life, added Massachusetts Institute of Technology
planetary scientist Richard Binzel another of the researchers. But Binzel added
that “one is careful to never say the word impossible.” Liquid water is
considered one of the essential ingredients for life. The discovery was made
through an analysis of images and data collected by NASA’s New Horizons
spacecraft, which flew past Pluto and its entourage of moons in July 2015.
