An interesting interaction which resulted in some rather long tidal streams outstretched from a spiral galaxy like arms. I'm not sure they could be considered as part of the arms or just streams.


I used Dark Energy Survey DR1 for color. Not quite sure on the filters for that. Will have to update the description when I figure it out, but it looks like a typical combination of near-infrared / red / green filters. I took the image straight off's viewer since I'm having trouble getting data access. Seems my email isn't working tonight.


If you take a look at the DES DR1 data in the legacysurvey viewer you can see there is a transient of some type near the center of the spiral galaxy. Could be a supernova, or it could just be a sneaky asteroid. It's hard to tell without a date/time for the observation that captured the transient, though.
