You can fill that out with lots of verbs, for example, "the majority of stars shine". Here are some others:* The majority of stars are smaller than our Sun.
* The majority of stars are main-sequence stars. That means that they fuse hydrogen-1, converting it into helium-4.
The majority of stars in our galaxy are red dwarfs, which are smaller and cooler than our sun. They make up about 70-80% of the stars in the Milky Way.
Outside our (Milky Way) galaxy.
Yes, stars can exist outside of a galaxy. These stars are typically referred to as intergalactic stars, and they may have been ejected from their original galaxy due to interactions with other stars or galactic dynamics. Intergalactic stars are typically found in the space between galaxies.
I guess that would refer to a star that is part of a galaxy. That would apply to the vast majority of stars.
No. The vast majority of stars in our galaxy are too far away to see, and many are hidden behind clouds fo gas and dust.
A galaxy is by a definition a group of stars. If there were no stars it could not be a galaxy.
Every galaxy contains stars, if that's what you mean. "Galaxy" means "big bunch of stars". No stars ===> no galaxy.
No, the vast majority of stars are outside the Milky Way galaxy. However, most of the stars we can actually see as individual stars are in the Milky Way. About the only exception is supernovae ... those are so bright that we can distinguish them even in other galaxies.
Stars form in all parts of our galaxy - not just the "arms". Stars do indeed form in the central bulge. The vast majority of hot, young, blue stars are formed in the arms, but stars also form in the central bulge as well.
Elliptical Galaxy The Elliptical Galaxy has mostly old stars and blue stars are new stars.
It is the galaxy in which our Sun is an orbiting star, along with another 200 to 400 billion stars. Astronomically, the Milky Way, since it is seen edge-on, defines the galactic plane in which the majority of its stars orbit.
A flattened combination of matter containing stars, gas, and dust in a spiral galaxy is identified as the galaxy's disk. This disk is where most of the galaxy's star formation occurs and contains the majority of its stars and interstellar material. The spiral arms within the disk are regions of higher density that enhance star formation.
