Curious Cometary Knots in the Helix Nebula

apod.nasa.gov — What causes unusual knots of gas and dust in planetary nebulas? Seen also in the Ring Nebula, the Dumbbell Nebula and the Eskimo Nebula, the knots' existence was not initially predicted and their origins are still not well understood.

  • DemDude, on 04/13/2008, -0/+8Sure. Same goes for xkcd comics ^^
  • epadafunk, on 04/13/2008, -6/+12My favorite part is every comment being dugg down.
  • linksus, on 04/13/2008, -4/+9This comment is only here to be buried.
    Thanks
    Please come again.
  • TeamoSupremo, on 04/13/2008, -1/+5I saw that too. They also said they weren't fragments of comets. It actually occurs naturally.
  • Bactame, on 04/13/2008, -0/+3Hi Aeroslin...i worked on fixing the problem for the companies that supplied the seals and hardware on that ship
  • Jookly, on 04/13/2008, -1/+3Well I was serious about being intrigued by how scalable the laws of physics are.
    I was joking about living in a Petri dish
    Can we be friends now?
  • Bactame, on 04/13/2008, -0/+2Strictly speaking 'space' is an undefined term
  • 471776, on 04/13/2008, -1/+3Sorry. But if you were actually saying that instead of being sarcastic, I wouldn't be at all surprised. Maybe I was affected by the YouTube comments I was reading a few minutes before.
  • OrangeCrush, on 04/13/2008, -3/+4Strictly speaking, it never actually got her into space.
  • 471776, on 04/13/2008, -4/+5Petri dish.

    And no, we aren't.
  • MJDub, on 04/13/2008, -7/+8Just saw this on the History Channel yesterday. Pretty amazing that those nebulas are over a light year across and stem from just a "little" star in the middle.
  • WTFppl, on 04/13/2008, -1/+2Very beautiful!
  • Aeroslin, on 04/13/2008, -7/+7It is theorized that when stars explode, new, heavier elements are created. I wonder if that's not what these fragments are? Perhaps in a few billion years these heavier fragments will find their way into a new star-forming region and become the catalyst for a new star or new planet.
  • breakaway, on 04/13/2008, -2/+2"Curious"
    Sounds like something Tuvok would say
  • themastersb, on 04/14/2008, -1/+1Underaged B&
  • chestertonb, on 04/13/2008, -4/+3I dug you up on purpose.
  • amanilaenvelope, on 04/13/2008, -8/+7Dear Digg.com,
    it seems that the digg up button is broken. fix?
  • dfymarine, on 04/13/2008, -4/+3hmmm.... sperms racing to the wombs..............................................
  • Aeroslin, on 04/13/2008, -7/+5'the exploding spacecraft' is called Challenger. I had troubles sleeping for about a week afterwards. I was 14 years old.
  • iamdon, on 04/13/2008, -5/+3InterGalactic Shag
  • Jookly, on 04/13/2008, -5/+2Well you never know when the internets are in a mood for a joke. Sorry gramps.
  • Jookly, on 04/13/2008, -8/+5Its amazing how the laws of physics can be seen at so many scales of size. You could make similar clumps in the lab.

    WE ARE LIVING IN A PETRY DISH!!!!
  • HayString, on 04/13/2008, -6/+3I buried everyone on this page for the hell of it.
  • genr8r, on 04/13/2008, -4/+1Oh, come on. That is just an image of Eliot Spitzer's sheets.
  • Lynxist, on 04/13/2008, -7/+4wow, that's trippy. it reminds me of a photo of a glass of effervescent energy tonic.
  • JulyZerg, on 04/13/2008, -7/+3In your mind?
  • selmer, on 04/13/2008, -7/+3I thought this was a electron microscope picture of a money shot
  • amanilaenvelope, on 04/13/2008, -8/+4no one has the truck balls to bury me !! i double dog-dare ya to bury me !!! listen to me. succumb to my request ! if you bury me based on what i told you then you've become my interweb bitch.
  • NathanCH, on 04/13/2008, -7/+3Looks gross yet beautiful.
  • mytibt, on 04/13/2008, -7/+2Looks like the opening scene of "Look Who's Talking"
  • Bactame, on 04/13/2008, -10/+5Each of those snowballs has approximately the size of the solar system and the mass of the earth. Reminds me of the pictures of the exploding spacecraft which carried that science teacher into space back in the 80's.
  • Verz, on 04/13/2008, -10/+4Pretty, but is it really front page material?
  • br0wnstar, on 04/13/2008, -8/+2Those are clearly souls that have left the earthly realm... come on!
  • Aeroslin, on 04/13/2008, -9/+2No, I live right here.
  • michelsonmorley, on 04/13/2008, -13/+4This is probably where God lives.
