Hi GB. This is a good entry. smiley - ok

You give the apparent size of the galaxy. It might be worth comparing it to the moon to give it scale. 190' is about 6times the width of the full moon. If M31 was brighter it would dominate the night sky. As it is, all we see without optical aid is the core.

This is an excellent article. smiley - smiley

I have only two queries:
smiley - starI wasn't sure of the relevance of the quote at the beginning.

smiley - starWhen I looked up the picture of M31 and M32, there was no reference to M32.

Hi both, thank you for reading and your reviews. Gnomon: I've added those pieces of informationsmiley - ok mvp, I am surprised that M32 isn't mentioned in that text considering it's quite prominent in the image. I've amended the title to "M31" and added a separate link entitled "M32". The relevance of the quote at the beginning, I know it's not specifically about the Andromeda Galaxy but Bruno no doubt saw it and his words resonate with me. We see the galaxies moving away (red shift) and coming towards us (blue shift) but we don't know why. It's the bit "and the observer is always at the centre of things" which gets to me. Also, his death was so horrific, I like to keep his name and words alive in my work.

I love that quote - it sent chills up my spine.

Wow. smiley - magic This is brilliant! Talk about taking the long view...

Could I make a teeny suggestion?

>>that it was bestowed with its correct description...<<

I think it would read better if you said, 'that it was endowed with its correct description,' or just 'given its correct description...'

You could also say, 'that the correct description of 'spiral galaxy' was bestowed on it for the first time in over 900 years of astronomical study.'

Anyway, lovely story, very exciting. smiley - biggrin

Elektragheorgheni -Please read 'The Post'

I really enjoyed this entry, Galaxy Babe. Thank you for packing so much information into such a readable form. And the pictures were great too--thanks NASA, about the only gov't agency we have that I don't begrudge my tax dollars going to. At least they provide us with a lot of great photos that can be shared.

Thanks Elektra, I'm happy if my astronomy scribblings pass the layman test. Too much science makes my head spin smiley - cdouble

I love the images too. I have been known to write entries around a fabulous image!smiley - magic

A very interesting Entry. smiley - smiley
I only have two comments:

How did Hubble know that it was in fact a galaxy and not a nebula?

You may want to put a footnote to 'galactic meal'.

Hiya Tav thanks for reading and your review smiley - smiley

Edwin Hubble wrote about it after the Great Debate (I link to my "From Spiral Nebulae to Galaxies Galore - The Great Debate of 1920" in the same part) when it was decided that galaxies were separate to the Milky Way.

Gnomon - time to move on

The follow two sentences seem to have got out of place:

If you began a journey from one edge of the Andromeda Galaxy to the other, it would take approximately 220,000 years at the speed of light. To see more than the galaxy's core, you'd need an optical aid like a telescope.

This seems to suggest that in a journey from across the galaxy, you'd need a telescope to see more than the core. I think you meant the sentence about needing a telescope to be part of the previous section about the magnitude and size of the galaxy. You should therefore swap these sentences around, but you may need to also reword them slightly. Something like 'The small grey blob we see in Andromeda with the naked eye is just the brightest part of the galaxy, the core. You'd need....'

Andromeda I, II, III, IV, V, VI (also known as the Pegasus Dwarf Spheroidal), VII (also known as the Cassiopeia Dwarf), VIII, IX, X, XI, XII, XIII, XIV, XV, XVI, XVII, XVIII, XIX, XX, XXI, XXII, XXIII, XXIV, XXV, XXVI, XXVII, XXVIII and XXIX

-- I think this list is a bit tedious. I suggest you reword it. Could you not just say 'the 29 galaxies simply known as Andromeda I - Andromeda XXIX' ?

In the Images section, you should start with the image M31 and change the title of it to 'The Andromeda Galaxy'.

A few minor points

eons -- is this the American spelling? I thought this was spelled aeons in British English, but am not sure.

on par with --> on a par with

'companion' Comet PANSTARRS -->
'Companion' comet PANSTARRS (capital C on Companion, small c on comet)

Thank you Gnomon. I have done all my updating but when I try to "update entry" it takes me to a Captcha page, where there is no image for me to copy to prove I am not a robot - I try to refresh but am getting just an "x" where the image (or word) should be. smiley - sadface

There are a lot of problems with the captcha system at the moment. The more often you edit, the more the captcha suspects you're a robot, so as a Guide Editor you'll be particularly affected. Apparently you can be added to the "white list" so that captcha always trusts you. Talk to Lanza about this.

Thanks Gnomon, I've already complained about the captcha.

It allowed me to update the entry this morning after I saved the text overnight in an email!

I've done all you suggested except for "eons/aeons" - I've only ever spelt it "eon" - I changed it to "aeon" and my spell-checker told me it's wrong. smiley - doh

It's good, GB, but I think it could be improved as follows. Move the sentence which starts

"If you began a journey from one edge"

to just after

"four hundred billion stars."

Then start a new paragraph with " The Andromeda Galaxy's angular diameter".

Other than that, I'm happy with it.
