Explanation: What's happening to this spiral galaxy? Although details remain uncertain, it surely has to do with an ongoing battle with its smaller galactic neighbor. The featured galaxy is labelled UGC 1810 by itself, but together with its collisional partner is known as Arp 273. The overall shape of UGC 1810 -- in particular its blue outer ring -- is likely a result of wild and violent gravitational interactions. This ring's blue color is caused by massive stars that are blue hot and have formed only in the past few million years. The inner galaxy appears older, redder, and threaded with cool filamentary dust. A few bright stars appear well in the foreground, unrelated to UGC 1810, while several galaxies are visible well in the background. Arp 273 lies about 300 million light years away toward the constellation of Andromeda. Quite likely, UGC 1810 will devour its galactic sidekick over the next billion years and settle into a classic spiral form.

I wonder if anyone has done any CGI work with the concept of these clashing bodies? Can you just imagine the sheer scope of these crashes? Like throwing HUGE snowballs at each other I’ll bet. Almost incomprehensible the true size of it all...
Wow.
When Spirograph is just way too simplistic.
After all of this time I finally thought to look at your home page. The only question I have is, “Did you, personally, take all of those beautiful photographs?” ;-)
This would look great on a shirt.
I took almost all of the photos on my profile page. The one where I am in the photo I had someone else take the photo, but I set the camera up.
You’re an excellent photographer! I was into photography years ago but in 1993 we had a house fire. Burned up all of my equipment but I wasn’t too concerned because I saw digital photography coming on the horizon. I think I still have a Canon A-1 somewhere.
Yes, many of the photos on my home page are from my mountain climbing trips.
