| Description | There are two galaxies in the frame: NGC 7714 is a distorted spiral galaxy that appears to be attracting stellar material from above and below. Below, the new material deformed a large spiral arm, out- and down-wards. 7714 has a very bright galactic center and the rest of the spiral disk is bright and well formed. NGC 7715 is much less bright, with a dim center. We appear to be viewing it edge-on, distorted into an integral sign shape that runs right to the edge (and behind?) 7714. The fact that 7714 is brighter and more intact suggests it is the dominant galaxy of the two. On reflection, I'm wondering if we're seeing a "near miss" with 7715 passing from bottom left to upper right, behind 7714. The stellar material below 7714 could be the initial stellar material attracted from 7715, which is continuing to give up material via the integral sign as it continues its movement towards the upper right.. |
