  1. It's called "dark" because it doesn't interact with any of the known forces except for gravity. No electromagnetic interaction means no light.
  2. Reminds me of the book "The View From the Center of the Universe." Basically humans are in the middle of the size scale between atoms and the universe, counting by orders of magnitude.
  3. I feel like Pluto is always a super popular subject for kids, especially since it's being visited this year. When I was that age I spent hours in the library reading books about planets (back in ye olde days before I had access to the internet). I would have loved to know about moons of other planets too.
  4. https://restructure.wordpress.com/2009/08/07/sexist-feynman-called-a-woman-worse-than-a-[removed word]/ An enlightening article about the man so many physicists worship, with an excerpt from Surely You're Joking, Mr. Feynman!
  5. So excited about 2015! Just one month away from visiting Ceres and a few more until Pluto, finally!!!!

      If you are a month away from visiting Ceres I am impressed with the wifi link back to here on earth.

  6. I agree lol! Physicists in general don't make much sense to the masses, which is such a shame.
  7. Does anybody know who is in charge of naming deep sky objects, or who to contact about suggestions? There are so many beautiful objects deserving of a better title than NGC####. Catalog ID's are also so hard to remember, but who could forget the Cat's Eye Nebula or the Ring Nebula? Here are some of my own personal nicknames. Got any of your own? Monarch Nebula (like the butterfly, since the "wings" are orange) Bullet Nebula Plasma Globe Nebula Aegis Nebula (looks like a magic shield to me) Sprinkler Galaxy
  8. Basically you subtract one from the roman numeral and that give you the number of missing electrons.
  9. My 'physics of stars' professor used to create stellar convection simulations and showed a bunch to our class. They looked very complicated, not nearly as neat and simple as you are describing. I believe he said magnetic fields and composition play a big part in determining convective behavior also, not just mass.
  10. Not sure if this is the place to put this. I've been using photoshop for years but only recently started playing with astronomy images. I wanted to bring out the details in images, especially the really bright parts that look like a haze. Here are some of my attempts:

    My own little tweeks to some public domain/creative commons images.
  12. My understanding is that gravity distorts space, making it not flat ("positive"), and dark energy distorts it the opposite way ("negative") . Our universe appears to have just enough dark energy to balance gravity, so that when you add them together you get zero which corresponds to space being (overall) flat.
