+[Locked in a cosmic embrace](https://throughlightandtime.com/ngc-7284-7285-lrgb-crop-cdk-1000-7-august-2023/), two large galaxies are merging at the center of this sharp telescopic field of view. The interacting system cataloged [as Arp 93](https://iopscience.iop.org/article/10.3847/2515-5172/ac9d3e) is some 200 million light-years distant toward the constellation Aquarius in planet Earth's sky. Individually the galaxies are identified as NGC 7285 (right) and NGC 7284. Their bright cores are still separated by about 20,000 light-years or so, but a massive [tidal stream](https://apod.nasa.gov/apod/ap150201.html), a result of their ongoing gravitational interaction, extends over 200,000 light-years toward the bottom of the frame. Interacting galaxies do look [peculiar](http://nedwww.ipac.caltech.edu/level5/Arp/frames.html), but are now understood to be common in the Universe. In fact, closer to home, the large spiral Andromeda Galaxy is known to be approaching the Milky Way. Arp 93 may well present an analog of their distant [future cosmic embrace](https://science.nasa.gov/science-news/science-at-nasa/2012/31may_andromeda/).
