What are all stars and galaxies in?
All stars and galaxies are in the universe.
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.
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.
the universe is made up of galaxies
It is impossible to list them all. There are 100 billion galaxies in the known universe, each containing millions to trillions of stars.
Generally older stars. Most, if not all galaxies have a supermassive black hole at their centre.
Yes, they do.
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.
There are 400 billion stars in our galaxy alone - we can't name them all because we haven't seen them all. There are BILLIONS of GALAXIES in our universe... Just think how many stars there are to name!
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.
All galaxies produce stars. Elliptical galaxies, due to their age, are less active in star production.
No, there are more massive galaxies with stars in them.
they all have billions of stars
See related questions.
No. Galaxies vary greatly in size, mass, shape, and number of stars.
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.
Galaxies are formed from stars
they all contain billions of stars that orbit the center of the galaxy. all galaxies are also moving very slow.
'Do all' you mean. And it isn't necessary for all galaxies to have black holes at their centre, but it is extremely likely for there to be black holes in all galaxies due to the life cycle of stars.
More than half of all observed galaxies are spiral galaxies.

All stars are suns. Suns are found in galaxies where there is material there to form them, so you don't really get stars that are completely on their own and not part of any galaxy. As it is, there is a huge distance between stars, but they all form parts of galaxies.
Main sequence stars are found in all galaxies.
All galaxies are made up of billions of stars.
By God. He is the Creator of all things
All of them have stars and space dust for sure.
All the stars you see orbit the center of the Milky Way. Stars in other galaxies orbit their galactic center.
Galaxies are the massive collection of stars. Therefore galaxies could not have formed without stars.
Galaxies are vast collections of stars. So I guess you could say that a big group of stars forms a galaxy. Our galaxy has many big clusters of stars within it, so not all star clusters are galaxies. If you have a cluster of several million or billion (or trillion) stars surrounded by a lot of empty space, that is probably a galaxy.
The number of stars, as in distant "suns", are large. In our solar system, there is one star. In our galaxy, there are many, many stars. In all the visible galaxies, the number is yet larger. And what about all the presumed galaxies beyond our vision?
It's possible, though there are relatively few stars that aren't in galaxies, and most of them started out in galaxies.
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
Yes all binary stars are part of the star system because all galaxies and universes have stars and you have to have at least two stars for it to be binary stars.
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 .
The same age as stars in other galaxies.
All galaxies contain hot blue stars...
That is not certain. The first galaxies might have formed as gas from which stars condensed. The stars may have formed first, and later gathered together as galaxies. It could be different in different galaxies. Stars continue to form in galaxies but it is still difficult to know which came first.
It's not "galaxy stars", but galaxies, that have the black holes at their center. All, or most, galaxies have a giant black hole at their center.
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.
The stars in all galaxies must move otherwise they would fall toward the center and create a gigantic black hole. By spinning, galaxies avoid that fate. Some irregular galaxies exist with stars going every which way. Gravity makes some stars give energy to other stars so some will fall toward the center of those galaxies. That might make irregular galaxies start spinning. Nobody knows, but irregular galaxies should have a whole lot more stars drop… Read More
Stars and Galaxies are related because a galaxy is a system of billions of stars, gases, and dust.
Both - all galaxies contain young and old stars.
Galaxies ARE groups of stars. Lots of stars though. Not just like 2 or 3...
Galaxies would have started to form a billion or so years after the Big Bang, which occurred some 13.7 billion years ago. As for stars, they are forming and dying all the time, and not all of them were made at the same time.
It has been suggested that "the total number of stars in the universe is greater than all the grains of sand on all the beaches on Earth." There may be more stars, as there are likely more than 170 billion galaxies in the observable universe, and there may be considerably more we cannot see. Galaxies have been observed that have as few as tens of millions of stars and as many as a hundred trillion… Read More
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".
Yes, stars are third cousins to most modern day galaxies.
What force keeps the stars in all galaxies together so that the galaxies don't break up into isolated stars?
It has been postulated that black holes inhabit the center of every galaxy, including our own, whose incredible gravitational pull keeps the galaxies together.
