Man kann es kaum glauben, aber das allererste Foto der Andromedagalaxie wurde am 29. Dezember 1888 vom Astronomen Isaac Roberts aufgenommen 🛰
Vergleichen Sie nun: ein Bild derselben Galaxie aus einem ähnlichen Winkel, aufgenommen vom Hubble-Weltraumteleskop im Jahr 2013.

I mean, outside of a lot of time having passed, how could anyone ever possibly take its picture from any other angle?
Hubble telescope really „adds details.“
+ Thanks OP, for the post 🤩
One of the most interesting things to me is that pretty much every individual star we see on both pictures is actually from our galaxy and thus much, much closer. We’re so used to seeing them as ‚background‘ that it’s hard to wrap the head around the fact that it’s actually the foreground 😉
Well, it is getting closer so it should be easier to see it.
That second one isn’t Hubble; Andromeda is huge and Hubble only has a tiny field of view. Hubble *did* take a mosaic at one point, but it only showed a small portion of the overall galaxy. Additionally, this doesn’t look to be in visible light; I think it’s ultraviolet.
This is actually an image from GALEX, not HST. The tipoffs are the highlighting of the bright star-forming regions in the arms and the relatively subdued contribution from the central bulge, which are signs that this is an ultraviolet image rather the visible spectrum composites we typically get as glamour shots from Hubble.
Would have been nice if they didn’t rotate the image 180°.
Also would have been nice if they were the same scale.
Also would have been nice if they chose a visible light image instead of near IR.
Ugh.
I have to say, she’s really gotten her act together in the last 125 years.
It’s not a similar angle! Those images are rotated 180 degrees with respect to each other. Don’t be fooled into overinterpreting apparent changes over time.
I’m bothered by the fact that the 2 images are not oriented and scaled in a comparable way. Typically here, both M32 and M110 are visible and could have been used as reference for that purpose
I am interested in how we’d take an image from another angle.
Well, yeah. We’re going to get better pictures now that it’s closer to us.
Seems to not add up there are galaxies in different places in each picture.
The first image is still quite incredible for something taken in 1888. That was more than 30 years before Edwin Hubble confirmed the Andromeda “nebula” was actually another galaxy.
