NASA has shared a captivating image of an interacting galaxy pair known as Arp-Madore 2339-661, captured using the Hubble Space Telescope. These galaxies are located approximately 500 million light-years from Earth and are in the process of merging.
Arp-Madore 2339-661
One of these galaxies is NGC 7733, the smaller galaxy in the lower right of the image, while the other is NGC 7734, the larger galaxy in the upper left. Interestingly, hidden within the spiral arm of NGC 7733 is yet another galaxy referred to as NGC 7733N. This third galaxy can be seen as a knot-like structure in the upper arm of NGC 7733, glowing with a different color than the arm and partially obscured by dark dust.
What sets NGC 7733N apart is its considerable additional redshift, indicating that it is most likely its own distinct entity and not part of NGC 7733. The European Space Agency (ESA) describes these galaxies as interacting gravitationally with one another and suggests that they are referred to in some scientific literature as a ‘merging group,’ meaning they will ultimately become a single entity.
This breathtaking image showcases a captivating “galactic tango” of these merging galaxies, and it has garnered significant attention since NASA shared it on their Instagram account, amassing nearly 700,000 likes.
