back to article The ice must flow: Dunes of frozen gas spotted on alien dwarf

Dunes of methane ice grains have been discovered on Pluto after scientists studied snaps taken by NASA’s New Horizons spacecraft. That's according to a paper published in the journal Science today. New Horizons, launched over a decade ago in 2006, has allowed boffins to conduct the most detailed study of the largest dwarf …

    Are we going to have the usual fight about what Pluto is?

    As far as I can tell it's not even a dwarf planet, just a crappy Kuiper belt object and not special at all.

    There I said it. Come at me.

      Not really bothered on the 'Save Pluto' front, but I do remember, years ago, reading that, although a ninth planet had been predicted from planertary perturbation (gravitic influence on orbital motion not accounted for by observed masses) for many years, Pluto did not appear to have either the mass or the orbit to account for these effects.

      Essentially, there was an undiscovered planetary mass (or lots of small masses in a relatively small region), which was the real 'planet nine', and whatever Pluto might be, it certainly wasn't that.

      Does anyone else remember that, or have I been carrying around my own personal Mandela effect for all these years?

        Since this article was mostly about grains of sand, maybe it was a Mandala effect? :)

        No, you are right. What you may have forgotten (or just not been aware of) is that NASA was able to make very accurate measurements of the mass of Uranus and Neptune when Voyager-2 made it's close approaches to them. They discovered that Neptune's mass was significantly different from the first estimate made by astronomers (I think it was about 4% heavier); when they dropped that into the orbital motion calculations the unknown perturbation disappeared.

        Interesting : ".... lots of small masses in a relatively small region... which was the real 'planet nine'..."

        After some Goggling I found this:

      It's a cartoon character dog not to be confused with Bluto who is Popeye's nemesis, problem solved.

        Then the hidden 9th planet is likely called Goofy... also a dog but takes Pluto out on a leash for walks(orbits).

      I think we can all agree Pluto* ain't the kind of place to raise your kids....

    Ecological catastrophe due to Clangers intensive farming practices

    Sadly they are the remnants of the rear end methane emissions of a too-large Sky Moo herd.

      So not the rear emissions of an enormous mutant star-goat then.

        No, whilst Minter's theories are expressed eloquently through the medium of computer games, they cannot hope to match the authoratative stature of a BBC Michael Palin travel documentary.

        "too-large Sky Moo herd"

        "the rear emissions of an enormous mutant star-goat"

        Dunno which it is, but something smells really bad about both those theories.

        I'll get my coat, it's the one airing out on the balcony.

    Size Matters

    Pluto is the second biggest dwarf planet in the solar system, the biggest being Eris, because size matters

      Re: Size Matters

      Current reckoning is that Eris has a greater mass than Pluto but Pluto is a little larger, and therefore less dense, than Eris.

    I just hope...

    That when we do eventualy find the Ninth Planet. We will name it Persephone and, more commony named Rupert after the discover's pet Parrort.

    Where there are dunes surely there must be giant worms!

      Giant, icy worms and a warrior-like band of free men. And a prophet. And a cross-generational conspiracy. Damn, that was a good book.

    Uranus is cold.

    There's a few ways of warming that up.

      The less I know about what you purport have knowledge of, the better.
