In the Sept., 2015 issue of Science News, scientists announced that Pluto's reddish layers are actually made up of a frozen mist floating approximately 130Km (81 miles) above the surface. The distance that this haze floats above the surface is a surprise to scientists. What is also remarkable is that this mist has collapsed back to the surface on over half of the orb! Where this mist came from, what it's made of, and why half of it has dropped back to the surface are just a few of the many questions that astro physicists are discovering as they pour through the stream of images that are returning to earth.
In November, 2016, scientists reported finding evidence that Pluto harbors a hidden ocean beneath the frozen surface of its heart-shaped central plain. Evidence suggests that this plain is actually the frozen surface of an ocean that contains as much water as all of Earth's seas.
The finding, reported in two research papers published in the journal Nature, adds Pluto to a growing list of worlds in the solar system beyond Earth believed to have underground oceans, some of which could contain life. Pluto's ocean, which is likely slushy with ice, lies 93 to 124 miles (150 to 200 km) beneath the dwarf planet's icy surface and is about 62 miles (100 km) deep, planetary scientist Francis Nimmo of the University of California, Santa Cruz 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."
