What are three sizes for galaxies?
Galaxies can be classified into three main sizes: dwarf galaxies, which are small and contain less than a few billion stars; Milky Way-sized galaxies, which are intermediate in size and contain a few hundred billion stars; and giant galaxies, which are massive and can contain trillions of stars.
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
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.
What is an irregular luminous band of stars called?
An irregular luminous band of stars is called a "galaxy." Galaxies are massive systems of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. They come in various shapes and sizes and can contain billions to trillions of stars.
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.

Which objects began to form in your universe earlier stars or galaxies?
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
Are all-stars in the same galaxy?
No, there are more massive galaxies with stars in them.
What type of galaxy is a massive blob of stars?
These are called ellipitical galaxies
What is a galaxy made of?
Gases and stars and a massive central black hole.
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.

Where are neutron stars located at in the universe?
Mostly in galaxies, where they can form Super Massive Black Holes.
What force keeps the stars in all galaxies together so that the galaxies don27t break up into isolated stars?
A super massive Black hole present in the centre of almost all galaxies have tedency to bind up all the things . Our milky also have super massive black hole in it's centre .
All the stars and galaxies are in this?
The universe contains all the stars and galaxies in existence. Stars are massive celestial bodies that emit light and heat, while galaxies are vast systems of stars, gas, dust, and dark matter bound together by gravity. Together, they make up the incredible tapestry of the cosmos.
What do galaxy's have in common?
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.
Why black holes are believed to reside dormant in normal galaxies?
Super massive black holes are believed to exist within galaxies (like our own) because stars in the middle of the galaxy are spinning too fast for there not to be something extremely massive there.
What is a vast collection of stars?
A vast collection of stars is called a galaxy. Galaxies are massive systems that contain stars, planets, gas, dust, and dark matter, held together by gravity. The Milky Way is an example of a galaxy that contains our solar system.
