From New Scientist: Some of these troughs are filled in with dark material, and others even contain small hills. It’s possible these shapes are created by convection within Pluto, heating and melting the surface likely a slowly bubbling pot of porridge. Or, they could be formed by contractions of the surface, similar to the processes that produce mud cracks on Earth. |

who tells u that Pluto is molten inside? without it, very little tectonic is possible...especially in that COLD environment, where everithing is so HARD 6 BRITTLE... ;) WoW...awesome science! ;) non-profit org. Play4Life in Zagreb, Croatia, EU |

Pluto’s Icy Plains, Pits and Mountains Take Shape in Tombaugh Regio http://blogs.discovermagazine.com/d-brief/2015/07/17/plutos-icy-plains-pits-and-mountains-take-shape-in-tombaugh-regio/#.Van9rEXDhp8 Maybe both Pluto and Ceres will be planets again:) http://blogs.discovermagazine.com/crux/2015/02/25/pluto-ceres-planet-again/ |

From NASA: Scientists have two working theories as to how these segments were formed. The irregular shapes may be the result of the contraction of surface materials, similar to what happens when mud dries. Alternatively, they may be a product of convection, similar to wax rising in a lava lamp. On Pluto, convection would occur within a surface layer of frozen carbon monoxide, methane and nitrogen, driven by the scant warmth of Pluto’s interior. |

It begins to look as if the 'heart' feature on Pluto could be the site of a large impact. Radial lines extending from a point within the left side of the heart are becoming apparent. This impact could have supplied the heat causing at least some of the geological phenomena, including resurfacing. It still seem difficult to connect such an impact with the raising of ranges of mountains made of water ice, though. Charon appears mostly uncratered, so may also have undergone large impacts, which could account for its relatively 'young' surface. |

Heart? No it's Pluto. |

Yes, it appears that Pluto was ready for his close up! Long may his tail wag! |

We all know that Pluto was named for the Roman god of the underworld, don't we? Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

Venetia Burney (later Venetia Phair), who as an eleven-year-old British schoolgirl had suggested the name Pluto for the planet, remarked in 2006: "The name had nothing to do with the Disney cartoon. Mickey Mouse's dog was named after the planet, not the other way around."[13] Although it has been claimed that Disney named the dog after the planet, rather than after the mythical god of the underworld, this has not been verified. Disney animator Ben Sharpsteen said "We thought the name [Rover] was too common, so we had to look for something else. ... We changed it to Pluto the Pup ... but I don't honestly remember why." Disney was very interested in space so I wouldn't be surpriced if he named the dog after the planet. |

Only a few months elapsed between the naming of the planet Pluto and the naming of Disney's Pluto, who was formerly known as 'Rover'. Then connection is not likely to be coincidental. The discovery and naming of the planet was pretty big news at the time. |

Ah yes, but the name of the (dwarf)planet came before the name of the dog. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

If you want to consider Pluto to be a planet, then it should be classified as an ICY PLANET along with the other icy planets that we have found and will find that are as big or bigger. This should fit in with the previous designations of: Here is a truly beautiful proposal that should just about end arguments (I hope): http://www.astronist.co.uk/astro_ev/_docs/Ashworth_planet_nomenclature.pdf |

I guess everybody's entitled to their opinion. It shall remain my belief that New Horizons achieved it's mission goals just like they reported it. Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |
