What else can I help you with?
Why scientist don't expect to find galaxies that have large blue shifts?
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.
Which of these galaxies would you most likely find at the center of a large cluster of galaxies?
At the center of a large cluster, you'll usually find large and massive galaxies.
What is one way that an elliptical galaxy differs from the other types of galaxies?
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
What is Virgo boundary?
The Virgo boundary, often referred to in the context of astronomy, is a large-scale structure in the universe that marks the edge of the Virgo Cluster, a group of galaxies. It is significant in cosmology as it helps delineate the large-scale distribution of matter in the universe. The boundary can also refer to the transition between different galactic environments or densities, influencing the formation and evolution of galaxies within and outside the cluster.
Can a group of galaxies contain hundreds of galaxies?
Yes, a group of galaxies can contain hundreds of galaxies. These collections are known as galaxy groups or clusters, with galaxy clusters typically housing dozens to thousands of galaxies. The gravitational attraction among the galaxies allows them to remain bound together within these larger structures. This clustering plays a significant role in the study of cosmic evolution and large-scale structures in the universe.
Are most galaxies spread uniformly throughout the universe?
Galaxies are not spread uniformly throughout the universe. They are actually structured into clusters, groups, and superclusters, with vast voids of empty space in between. This distribution is influenced by gravity and the large-scale structure of the universe.
How does the galaxy get bigger?
Galaxies get bigger by a process of merging. The gravitational attraction of the galaxy and the dark matter round it pull in satellite galaxies and these merge with the main galaxy. Eventually large galaxies merge to form large elliptical galaxies. look at the link below.
What is the relationship between the expanding universe and the distances between stars and galaxies?
This is mostly theory, Galaxies are made of billions of stars. For some reason Galaxy's hold on to their stars. We do not really understand how galaxy's can yet hold their form like this. Our math so far has trouble with making sense of this. When comparing one galaxy to another, size becomes so large words are hard to describe the distance of space. There is an an incredible amount of space between everything out there. What is the distance between galaxies, why is it there, The expanding universe is trying to explain the growing spaces between galaxies yet the galaxies appear to stay bound to themselves.
Do dozens of dwarf galaxies merge and form into a giant elliptical galaxy?
Not just dwarf galaxies. Giant elliptical galaxies lie likely the result of many galaxies, small and large, merging.
What are two categories of the size of galaxies?
Large and Dwarf.
What is the estimated number of large galaxies since there are 100 billion galaxies in the universe?
If you counted 1 galaxy per second, it would take ~3200 years to count all 100 billion galaxies in the universe.
What are the names of some irregular galaxies?
Canis Major Dwarf and Small Magellanic Cloud are irregular satellite galaxies of the Milky Way.The two irregular galaxies that orbit the Milky Way are the Large and Small Magellanic Clouds.
