Image of NGC 520 (Arp 157)
|
Arp 157 in Pisces is actually two spiral galaxies in the process of colliding and eventually merging.? The two galactic nuclei haven't merged yet and you can see one of the two as the brightest area lower left of center.? The spiral arms of the two galaxies are essentially passing through each other and are being stretched out into these strange shapes because of gravitational forces.? Eventually, the whole process is likely to reach stability in the form of an elliptical galaxy. These are two of the brightest interacting galaxies in the sky and were discovered by William Herschel in 1784. The image was captured during 4 nights in November 2023 from SkyPi Remote Observatory under fair conditions using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final LRGB integration of 17.5 hours.
Thanks for looking, Bruce W. |
