back to article Astroboffins trace mysterious noise from hard rock in space

The source of unusual faint pockets of microwave radiation found only in a few regions of the Milky Way has been traced back to tiny specks of nanodiamond dust. A paper published in Nature Astronomy on Monday cracks the mystery of anomalous microwave emission (AME). It was first discovered in the late twentieth and early …

    Arthur C Clarkes "2061"

    weirdly I was reading this last week (sleepless night) where the premise is diamonds can be created in gas giant type planets. I think there's a 1980s NASA paper on it ?

      I'm sure I read that some planets may have cores of diamond the size of the moon. That would make a dent in De Beers profits

        White Dwarf cores are supposedly mostly diamond.

    Uh oh...

    Are we sure this isn't a sign of Star Trek's crystalline entity?

    The radiation must represent a loss of energy so their spin should slow. Is there a mechanism to spin them up again?

    1. Blockchain commentard Silver badge

      Yes, look at the Powerballs (many YouTube videos) and see how you can manually spin them up to speed.

      At some point will they stop spinning and emitting?

      "The radiation must represent a loss of energy so their spin should slow. Is there a mechanism to spin them up again?"

      They seem to be mainly in protoplanetary discs, so the source of energy will be gravity - as the disc contracts gravitational potential energy is converted into kinetic energy, and some of this can be converted into spin (still kinetic energy, but individual rotation rather than bulk movement) through collisions.

    Diamonds in Uranus. Like that Bond film.

    "polycyclic aromatic hydrocarbon (PAH) molecules scattered throughout space."

    Not possibly a remnant of the Big Bang, (originally coined as a derogatory term for the theory of rapid expansion from a singularity.)

    but instead it may have been actually the 'Big FOO', a space fart leaving aromatic hydrocarbon distributed among the galaxies.

    Nanodiamonds emitting micro & terra waves what was the driver stimulating the diamonds to emit?

      Perhaps we should live in fear of the coming of the Cosmic Freshener Aerosol

    My god, it's full of

    spinning nanodiamonds... er, was that all right, Mr Kubrick?

    Kind of like the spinning pulsar "light houses" but on a nano scale

    But with enough of them working together you get something you can see across 100s of LY.

    Impressive detective work. Thumbs up.

    Sadly not really viable as a new way to make GHz radio signals.

    Was it AC/DC, Whitesnake, Steel Panter or Nightwish?

      +1 for Nightwish \m/

        ...but I'm a bit worried about who"Steel Panter" is

          Sorry, I meant Steel Panther.

    Nothing new here, the diamonds were quite well known to be up there in the sky. But where did Lucy go?!?

      According to Wikipedia

      she's still in the same place where she's been for 3.2 million years - Ethiopia. Seems she's a bit of a stay-at-home girl. (although I believe she did once do a world tour).

    Oh great, they've discovered Space Elevator Music...

    Or is it Erich Zahn just getting started?

      Um, it's sick. My best friend's sister's boyfriend's brother's girlfriend heard from this guy who knows this kid who's going with a girl who saw radiation pass out at 31 Flavors last night. I guess it's pretty serious.

    So, the aliens only go to the systems with diamonds.

    "nanodiamonds that are so tiny, they cannot be seen by most microscopes."

    When was the last time a microscope was used on these protostellar disks?
