| Description | At the heart of Arp 170 is a merged, curved, diffuse envelope of what (from the shape) are at least two elliptical galaxies. However, a total of 5 or 6 possible galactic nucleii track the same curve as the envelope. Are they all galactic cores, or are some asterisms? I can't tell and even the Palomar image doesn't disambiguate it much. In the inverted image there is a triangular shaped counter-tail extending NNE which circumscribes a trapezoidal pattern of 4 likely, tiny galaxies or galaxy-fragments. There's just a hint in my capture that the plume continues to the medium sized spiral galaxy, seen edge-on, in the SE corner of the image. A smaller, roughly triangular counter-tail extends SSW from the last two bright object in the main curve. They extend towards another "spec" which could well be another tiny galaxy. |
