What else can I help you with?
Are space galaxies all the same size?
No, space galaxies are not all the same size. They vary widely in size, ranging from dwarf galaxies with just a few billion stars to giant galaxies containing trillions of stars. Factors such as their formation history, environment, and interactions with other galaxies contribute to these differences in size. Additionally, galaxies can change over time due to mergers and gravitational influences.
Are the stars you see at night from other galaxies?
No. All the stars you see at night are in our galaxy. Stars in other galaxies are much too far away to be seen without a powerful telescope.
Along with shape and size which property distinguishes spiral galaxies elliptical galaxies and irregular galaxies from one another?
You can also distinguish them by the types of stars - older stars versus younger stars, and stars of different "metallicity".
What are billions of stars?
galaxies
In which types of galaxies is concentration of stars more centrally located?
The concentration of stars is typically more centrally located in elliptical galaxies compared to spiral galaxies. Elliptical galaxies have a more concentrated spheroidal shape with stars distributed densely in the center, while spiral galaxies have a more spread-out disk structure with stars distributed along spiral arms.
What are all stars and galaxies in?
All stars and galaxies are in the universe.
Which stars are actually a galaxy?
No stars are actually a galaxy. All stars are stars and all galaxies are galaxies. Stars are found in galaxies. Some galaxies look like tiny dots in our night sky, so might look like a star, but they are not stars; they are galaxies.
What has all the stars and galaxies in them?
the universe is made up of galaxies
What are all the galaxies?
The collection of all visible or detectable galaxies is known as the universe. Each galaxy is a vast collection of stars--billions of them. Some galaxies have trillions of stars.
What are all the stars and galaxies in?
The Universe.
What is all galaxies and all their stars?
It is impossible to list them all. There are 100 billion galaxies in the known universe, each containing millions to trillions of stars.
Is this true an elliptical galaxy has mostly old stars?
Both - all galaxies contain young and old stars.
Are all-stars in the same galaxy?
No, there are more massive galaxies with stars in them.
What galaxies are massive blobs of stars?
Elliptical galaxies are massive blobs of stars characterized by their round or ellipsoidal shapes. These galaxies are composed mainly of older stars and have little to no ongoing star formation activity.
Explain how all galaxies are similar?
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
How many stars are in a cluster?
A cluster is a collection of galaxies, normally less than about 50 galaxies. All clusters are different and all galaxies are different. A ball point figure would put the maximum number of stars at around 10,000,000,000,000 stars or 10 trillion.
Do all galaxies contain billions of stars?
Yes, most galaxies contain billions of stars. For instance, our Milky Way galaxy is estimated to have around 100 to 400 billion stars. However, there are smaller galaxies, known as dwarf galaxies, that may contain as few as a few million stars. Despite this variation, the majority of galaxies are star-rich and typically hold vast numbers of stars.
