Description
ARP 273 is a peculiar pair of galaxies located in the Andromeda constellation, approximately 300 million light-years away from Earth. It consists of two interacting galaxies that are in the early stages of interaction. The unique aspect of this galaxy pair is that the mutual gravitational forces between the two galaxies have distorted and stretched their shapes, forming a structure resembling a rose.
In ARP 273, the larger galaxy, UGC 1810, has a twisted spiral structure, with its spiral arms extending outward to form beautiful arcs. This distortion is believed to be caused by the gravitational influence of its companion galaxy, UGC 1813. The smaller galaxy in ARP 273, UGC 1813, appears to be passing through the outer region of UGC 1810, which is intensifying the gravitational interaction between the two galaxies. Due to the gravitational effects, UGC 1813 shows significant star formation activity.
The brightest orange star in the image, HD 14511, is a binary star with a separation of 2.2 arcseconds between the two stars. The slightly split star spikes in the image indirectly indicate this separation.
Revision B is the comparison with HST's work.
