Discussion Overview

The discussion revolves around the images of the Space Shuttle Atlantis as it transits in front of the Sun, as well as questions about the authenticity of photographs of the Milky Way galaxy. Participants explore the technical aspects of capturing such images and the nature of astronomical photography.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants inquire about the method of capturing images of Atlantis in front of the Sun, questioning the apparent size of the shuttle relative to the Sun.
  • One participant explains that the Shuttle appears small due to its altitude, comparing it to an airplane at a lower altitude.
  • Another participant provides details about the telescope and camera settings used to take the images, emphasizing the importance of magnification and distance.
  • Questions arise regarding the authenticity of images of the Milky Way, with some participants asserting that such images are not direct photographs but rather artistic representations.
  • Some participants discuss the challenges of photographing the entire Milky Way due to dust obscuring the view from within the galaxy.
  • There is mention of the number of galaxies in the observable universe and the ability to see out of the Milky Way, depending on the direction of observation.
  • One participant suggests that while we cannot take a picture of the entire Milky Way, we can estimate its shape based on star counts in various directions.

Areas of Agreement / Disagreement

Participants express differing views on the nature of images of the Milky Way, with some asserting they are real photographs while others argue they are artistic conceptions. The discussion remains unresolved regarding the authenticity of specific images and the methods of capturing them.

Contextual Notes

There are limitations regarding the assumptions made about the size and distance of celestial objects, as well as the definitions of what constitutes a "real" photograph in astronomical contexts.

Who May Find This Useful

Individuals interested in astronomy, astrophotography, and the nature of celestial imagery may find this discussion insightful.

Never? What about those thaken by M31 inhabitants?



nah, those were fake, it was obvious man, they were photos of their dashed trash :biggrin:

and the bottom line of this is that there’s no real photo of the Milky Way and will never be [of the entire galaxy] :approve:
Correct. And one more thing: The way you worded your original question sort of implies you've seen a lot of photos purported to be of the Milky Way Galaxy. That would surprise me - there aren't a lot of simulations of it out there. Sometimes when a news article has something about our galaxy, they'll include a photo, but it seems to me that most of the time they use a photo of some random sprial galaxy and are relatively clear that that's what they've done. For example, here is an article with two photos:
A galaxy like[emphasis added] the Milky Way as viewed from the top, and the actual Milky Way as viewed in the infrared [from the edge, as we see it]

He's most likely talking about the artist conceptions he's seeing that show up in an image search. I just searched for "Milky Way" in Google Images and it's amazing how many "spiral" images show up.
