Is that a merger of galaxies taking place behind 1309 at about 10:00 or just an odd shaped galaxy?

Probably somethimg along the lines of our own LMC (Large Magellanic cloud) satalite galaxy.

Hello

The galaxy on the left has gone through a collision.

And in the future it will collide with this galaxy.

[orin stepanek]

It's hard to tell if it went through a collusion. I don't see an invading galaxy; unless we are seeing a combination of the two together. A small galaxy? BMAONE23 may be right. Can't really tell. Also; the two reds at 5:00 seem kind of fussy. May these be stars out of focus or distant galaxies?

My vote is for a very seriously disturbed galaxy.

Something has altered its swirl big time.

That something is not easily seen tho, and speculations are numerous.

To add to the info is to add mor images of colliding galaxies

see link

and they keep on telling us that the universe is expanding.

Hi Harry! It does look a little like this. http://antwrp.gsfc.nasa.gov/apod/ap990525.html
But here you can see the invading galaxy.
Nice group of colliding galaxies.
The two reds at 5:00 on first post must be stars.

Hello Orin
this link is also on another post.

But! I have been thinking about this one for a long time.

Whyare the arms streched?

Its as though another galaxy is pulling the galaxy sideways,away from .

Got to think about this one.

Thanks orin

They are not out of focus. Everything in this image is so far away that for the purposes of focal control they can all be considered to be at the same distance: infinity. There are examples of in-focus red stars. There's a nice one at 1 o'clock, and it looks nothing like the red objects at 5. They are most likely isolated, distant elliptical galaxies with ancient star populations.

Hello Barakn

What do you mean by infinity?

[Pete]

barakn's right - since astronomical objects are so far away, incident light rays are essentially parallel. If one part of the image is in focus, the entire image will be in focus.

[orin stepanek]

OK; I see the red Star at 1:00; also there is an elliptical red galaxy below it. So why would these galaxies look red? Is this the natural color and are they actually red? You wouldn't think all the stars would be that ancient. The distance of these must be astronomical; making them even older today.

I found my own answer!

Wow! Some of these are twenty times longer than the Milky Way.

Hello Orin

What does that link tell you about the Big Bang and the Expansion of the universe.

[orin stepanek]

Hello Harry! I don't know that it does. I found the link looking for the red color of elliptical galaxies. It has a lot of interesting observations about galaxies. I guess I never thought of a quasar as a galaxy before though. What do you see in that link?
