Discussion Overview

The discussion revolves around the visual representation of the Andromeda Galaxy as it might appear if its stars were significantly brighter. Participants explore the credibility of the image presented, its artistic nature, and the differences between artistic impressions and actual observations through telescopes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express curiosity about the credibility of the image and whether it is an artist's impression or a processed photograph with exaggerated brightness.
  • There is a suggestion that the image is artistic rather than scientific, with one participant appreciating it while noting it may not be misleading.
  • Participants discuss the perception of the Moon's size compared to Andromeda, highlighting how people often misjudge celestial sizes when not directly observed.
  • One participant notes that the artist combined a typical image of Andromeda with an original photo, scaling it appropriately to represent its size relative to the Moon.
  • There are conflicting views on how Andromeda appears through a telescope, with some stating it looks nothing like the artistic representation, while others believe it resembles a photograph.
  • Another participant suggests that the image may be derived from a combination of different telescope captures, indicating a complex production process.

Areas of Agreement / Disagreement

Participants generally express uncertainty about the nature of the image, with multiple competing views on its artistic versus scientific validity. The discussion remains unresolved regarding the accuracy of the representation compared to actual observations.

Contextual Notes

There are limitations in the discussion regarding the definitions of artistic impressions versus actual astronomical images, as well as the assumptions about how brightness affects perception.

Hi everyone. The next link shows how the Andromeda should look like (from the Earth's surface) if its stars were much more brighter than they are (or if we could have a super-vision).

It seems so amazing as I couldn't even imagine how close the Andromeda is to us.
However, I'd like to verify this info (as I don't know the credibility of this site).
What's your opinion? Do you agree with this image?
 
Astronomy news on Phys.org
It looks reasonable to me, but I don't know if this an 'artists impression', or has somebody processed a real photo with the pixel brightness exaggerated,
Either way it's art rather than actual science, I like it though, and I wouldn't say it's misleading
 
This seems reasonable to me. The Moon's actual image is a lot smaller than image that most of us have in our mind's eye. The full moon only subtends about 1/2 of a degree, and Andromeda is a few degrees in image size.

Are you familiar with the two stars (separated by 5 1/2 degrees) in the Big Dipper that point to the North Star? On moonless nights I sometimes ask friends "How many full moons will fit between those two stars?" A typical response is "about four", which isn't close to the correct answer, "eleven." When we can't see the Moon, we think the Moon is bigger than it actually is.

If you read the text you'll see that the artist took a typical image of Andromeda and added it to the original photo, but in an appropriate scale (i.e. 3 times wider than the moon is).
 
Yes, I discovered that after my previous post, it seems to be a pretty good idea for a way of doing this image with fair accuracy.

a complete artists impression of the galaxy ... it looks nothing like that through a scope

Yes, it looks nothing like that through a scope with your eyes, but it looks like a photo to me.

I think that the artist used this photo:

This photo is just flipped, rotated and scaled. (I can't find how this Andromeda's photo has been produced but it seems to be a combination of different captures through a telescope, as the several "circles of views" depict.)
