Gravity - from the stars, dust, etc., but especially from "dark matter", a substance of yet unknown composition.

How does gravity affect the galaxy?

Gravity plays a crucial role in galaxy formation and evolution. It acts as the force that pulls gas and dust together to form stars and holds together the structures of galaxies. Gravity also influences the motion of stars and other celestial bodies within a galaxy, shaping its overall structure and dynamics.


What are the different parts of a galaxy and how do they contribute to its overall structure and function?

A galaxy consists of stars, gas, dust, and dark matter. Stars provide light and energy, while gas and dust form new stars and planetary systems. Dark matter holds the galaxy together with its gravitational pull. Together, these components create the structure and function of a galaxy, shaping its appearance and influencing its evolution.


What holds stars together to form shapes of galaxies?

GRAVITY!


Please answer quickly as possible. What is a group of stars that from a galaxy?

If they form a galaxy, it's called a galaxy of course.


What does a group of many stars dust and gas held together by gravity form?

A galaxy


What is a huge group of stars that form a spreading spiral?

A galaxy is a huge group of stars that form a spreading spiral. Our own Milky Way galaxy is an example of a spiral galaxy.


What name is givin to the huge group of stars that are close together?

A star cluster or a constellation can be a name given to a close knit grouping of stars. A group of constellations will form a galaxy..


Why do new stars form in the arms of a spiral galaxy and not in the central bulge?

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.


How constellations different from galaxies?

Constellations are stars put together, usually to form a ancient figure in the stars, a galaxy is much different, They have planets and in galaxies you can find constellations. Big difference


Is Milky Way galaxy come from stars?

Is constellation a galaxy?

No. A constellation is a collection of stars that form a recognizable shape. All the stars we see in the constellations are in our own galaxy, the Milky Way.


Can a galaxy die?

yes a galaxy can dieone way a galaxy can die if another galaxy collides with a smaller galaxy even though the result is a larger galaxy the smaller galaxy died because it no longer exzitesa galaxy is a huge cluster of stars. even though in a Large Galaxy such as a spiral with enough gas to form new stars, when a star dies out, the energy collides with the gas to form new stars.But in a galaxy that is small and dim such as eliptical galaxies with dim low solar mass stars it would not have enough energy to form a new stars because the gas is far apart and not enough to form new stars. so if all of the stars die out there would be no new stars get formed all that would be left are dense cores called white dwarfs,black holes and neutron stars and some dust. there would almost be no light generated by the galaxy.but not all galaxies die out(FOUND OUT FROM AN ASTROMNER)
