parabola Posted June 16, 2022 Share Posted June 16, 2022 Greetings! I joined this forum because I need help finding photos online of particular types of galaxies that I can email to my brother --- the photos, not the galaxies! I joyfully watch cable programs on the Science Channel about the cosmos. Maybe a few years ago, I distinctly remember seeing photos of amazing galaxies --- I think they were galaxies --- that were either the shapes of 3D parabolas or 2 back-to-back 3D parabolas. (Excuse my brain fart, but I can't think of the name of the shape of a 2D parabola extended onto 3 dimensions.) If not galaxies, maybe they were nebulae. Picture a perfectly smoothly curved bowl or 2 such bowls back-to-back. I just spent over an hour searching the web --- I don't use Google. I can't find such a picture! I did find a few nebulae, the crab nebulae, i.e.; but I thought I had seen photos of structures that were very much more clearly the shapes that I have described. I also recall that the program mentioned, and maybe showed with a photo, that over a wide space of the universe(?) or our galaxy(?), the axes of these structures were directionally aligned. The photo(s) were not close-ups. They were far enough away to see the entirety of the structures... maybe that made them appear more distinctively smoothly shaped. Am I remembering this wrongly? Were they nebulae?... something else? Where can I find such photos online? Quote Link to comment Share on other sites More sharing options...
