This one just might be a merger at near angles?
I've seen an image elsewhere like this that was classified as a merger.
What do experts think?


Well that should be the 16th of my initial Hubble Spiral posts. Phew...
If I've overstepped the bounds or done something wrong please tell me ;D

Seems to me I've seen this one before.  SDSS?  That acute angle bend at 7 o'clock seems mighty familiar. :-\

Awfully pretty.  Six arms, do you think?  :D No link in My Galaxies suggesting it could be a DR7/Stripe82 image, which I did see once.  The morphology looks quite "modern".  I wouldn't have been surprized to see somthing like this show up in DR7.  Don't know what, if anything, can be inferred from the blue color.

Beautiful indeed. As a lay person (not even an amateur astronomer) simple questions abound.
How do some galaxies get so many spiral arms from just two jets at the nucleus?  Do the jets pulse?
Or do the arms split?  One early SDSS galaxy in the ZOO-2  'Stunning Sights' - 'Your Best Spirals' thread seems to have 12 or more arms:


587741490907512900

Does anyone know the maximum number of spiral arms that have been found in a galaxy?
Tracing arms back doesn't answer my questions. Closer to the nucleus becomes blurry on most images.
Guess I'll have to study more theory on line... But that cuts into classifying time  :-\
