Hi Harry! You went back a long way to find this one. Seems like there was a more recent photo of the double nucleus. I don't remember where I saw it.

Hello Orin

Did not go back, someone posted to me and yes I think there is a recent one.

Be back later, I think I have it.

Got to pick up the kids.

Try http://antwrp.gsfc.nasa.gov/cgi-bin/apo ... search?m31 .
Some of those are lovely.
The rest are just awesome.
Though http://antwrp.gsfc.nasa.gov/apod/ap061228.html is a little
unrealistic. It would be nice if M31 was that bright. I might see it
if it were.

Hello Sitting downman

If you kept your eye open for a long time maybe you may expose the image.

I tried, does not work.

Unfortunately, for our eyes to perceive motion as they do, they need to refresh the image being sent to the visual cortex at a rate of about 30 times per second. This doesn't allow for us to be able to "SEE" this deep without some aide. You would need to be able to interfere with the transmission of light from your retina to your visual cortex for about 30 seconds (and keep your head and eyes perfectly still and fixed for the same time period) then send the collected light at once to see this image

Hello BMAONE23

Now you tell me, after my eyes become blinded by the star light.

Reminds me of:

Olber's Paradox:
http://abyss.uoregon.edu/~js/cosmo/lectures/lec05.html
The oldest cosmological paradox concerns the fact that the night sky should not appear dark in a very large (or infinite), ageless Universe. It should glow with the brightness of a stellar surface.
