What 3 things is a galaxy made of?
A galaxy is made of stars, gas, and dust. Stars are the primary source of light and energy in a galaxy, while gas (mostly hydrogen and helium) is the raw material for forming new stars. Dust consists of tiny solid particles and plays a role in cooling and forming new stars.
What are the types of matter new stars can form from?
New stars form from the interstellar gas and dust; mainly hydrogen and helium.
Why is Mars mostly sand and dust?
Mars has mostly dust because it has no magnetsphere.
Explain how scientist know that elliptical galaxy do not contain many young stars?
Scientists know that elliptical galaxies do not contain many young stars because observations have shown that they have mostly older stars with low levels of interstellar gas and dust needed for star formation. This lack of gas and dust suggests that these galaxies have exhausted their supply of materials for forming new stars and are no longer actively forming young stars.
How The universe is mostly made up of what a. Gases c. Dust b. Empty Space d. Stars?
D: Empty space.
What forms the Milky Way galaxy?
The Milky Way galaxy is made of stars, dust clouds, planets, comets, and other astronomical objects, probably including a black hole at the center, but mostly stars.
What are galaxies mainly made of?
Galaxies are mainly made up of stars, gas, and dust. Stars are the primary components, with gas (mostly hydrogen and helium) and dust filling the space between the stars. Dark matter is also thought to make up a significant portion of a galaxy's mass, even though it cannot be seen.
Name 3 items found in space besides stars moons planets?
Galaxies - massive collections of stars, gas, and dust held together by gravity. Nebulae - clouds of gas and dust in space where new stars are born. Black holes - regions of space with such strong gravitational forces that nothing, not even light, can escape.
Are larger solar systems made of gas and dust?
No. They are made mainly of stars and planets. The stars and planets came from gas and dust.
What are moon and stars made of?
the moon and the stars are made out of moisture and dust
What is the cloud of material stars are made of called?
The gases and dust from which stars condense are called cosmic dust or particles.
What destroyed crops besides dust storms?
