What else can I help you with?
Are some galaxies very small and have only a few thousand stars?
These small galaxies are believed to be the result of collisions between larger spiral galaxies. During such collisions pieces of the spiral arms get flung out into space, becoming small irregular galaxies.
Are there any stars between Galaxies?
Yes, there are stars between galaxies. When there are collisions or interactions between galaxies, stars can be ripped out of the galaxies. These stars will then wander into space between galaxies. Such stars have been observed with the Hubble Space Telescope. Taken from http://curious.astro.cornell.edu/question.php?number=384
What phenomena are not thought to be results of collisions or other interactions between galaxies?
When you ask a "Which of the following..." question, you need to offer some choices. We're unable to read your mind, to know what distractors were on your quiz.
Are there any individual stars in the space between galaxies?
Yes, there are. These generally come about when they are ejected from their host galaxy by the huge gravitational interaction involved in the collisions of galaxies.
What are the release dates for Cosmic Collisions - 2009 Galaxies 1-3?
Cosmic Collisions - 2009 Galaxies 1-3 was released on: USA: 28 January 2009
Why are galaxy collisions common in the universe?
Galaxy collisions are common in the universe because of the vast distances between galaxies and the gravitational forces that pull them towards each other. Over time, these gravitational forces can cause galaxies to collide and merge, creating new and larger galaxies.
What evidence do you have that galaxies collide with one another?
Observations of galaxies captured by telescopes like the Hubble Space Telescope show distorted shapes and tidal tails, indicating interactions and collisions between galaxies. Redshift data also reveals galaxies gravitationally interacting and merging as they move closer together in the Universe. Computer simulations based on astronomical models also support the theory of galactic collisions.
Who thought of galaxies?
astronomers did
Why are galaxy collisions of interest?
They create larger galaxies. Sometimes they can make mysterious celestial happenings....
What determines the shape of a galaxy?
That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.That is related to their past history.

Active galaxies are thought to be powered by?
Active Galaxies are thought to be powered by rotation
What is between the galaxies?
There's nothing between the galaxies. It's just other galaxies that float around the universe.
