@PaXx I am not sure what you mean. If you are referring to a satellite galaxy as in the Moon is a satellite of the Earth because it orbits ta plane the Earth, then yes. The Milky Way has many satellite galaxies. For the most part the solar system is confined to a plane called the ecliptic plane. Groups and clusters of galaxies appear to be characterized by galaxies whose orbits are randomly oriented--not confined to a specific plane.
This truly enhance my comprehension of the universe. When they say the universe was expanding, I was picturing the galaxies to just fly away in some direction, never looking back. So its really intriguing to see them whirling, back and forth, around each other, colliding several times. Ive never picture clusters to behave that way. thnaks!
It is my pleasure. It was fun making the video, and the intent was for it to be instructional. However, the galaxies are flying apart but only on a certain size scale. At the current age of the universe that size scale is > ~30 million light years. On scales smaller than that gravity has halted the expansion, and allowed dynamics such as the example movie above. Thanks again for your comment.
Could a galaxy have a "moon galaxy"? Looks like that. Would be cool to see a solarsystem with galaxies instead of a sun and planets
