ASTRO: The other Taffy galaxy pair

More interesting visually than the first pair I posted is UTC 12915 and
UGC 12914 east to west (left to right). Here there is some visual
evidence of the molecular connection between the two. Note the very
faint reddish band between them. This is very similar to the few
Extended Red Emission nebula I've featured. Dust pulled from these
clouds by the taffy connection is glowing from the ultraviolet light of
hot stars in the two galaxies. This isn't ionized hydrogen as the
ultraviolet light isn't sufficient for this but it can light up the dust
pulled out along with the gas from the collision. This pair is a bit
closer to us at about 185 million light years.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Rick, thanks for posting. Interacting galaxies are the most fascinating
"genre" for me.
