Why do astronomers propose that the Milky Way Galaxy contains a lot of dark matter?
Oh, well this is an interesting question, and a fun one to answer!
Basically, dark matter is proposed to exist because of the observations of interacting masses both within and between galaxies. (Note that it is not just the Milky Way that is proposed to contain dark matter; rather, 84% of the universe is hypothesized to be made of dark matter.) Basically, the total mass of all the stars and planets and other celestial objects should not be enough to cause the effects of gravitational lensing, solar revolution, etc. that are observed. Therefore, dark matter is proposed to exist; a type of matter that only interacts with gravitons and W bosons (only interacts with gravity and the weak force) and that is entirely undetectable.
What else can I help you with?
What is found in the Milky Way galaxy's galactic halo?
"The halo primarily contains individual old stars and clusters of old stars ("globular clusters"). It may be over 130,000 light years across. The halo also contains "dark matter," which is material that we cannot see but whose gravitational force can be measured." to shorten the answer - individual stars, clusters, and dark matter.
What is inside the Andromeda galaxy?
The Andromeda galaxy contains billions of stars, gas, dust, and dark matter. It also has a supermassive black hole at its center, along with star clusters and nebulae. The galaxy is located about 2.537 million light years away from Earth.
What you call a vast group of stars?
A vast group of stars is called a galaxy. Galaxies are large systems of stars, gas, dust, and dark matter, bound together by gravity. The Milky Way is an example of a galaxy that contains our solar system.
What is in the Andromeda galaxy?
The Andromeda galaxy contains an estimated 1 trillion stars, along with gas, dust, and dark matter. It is also home to various types of celestial objects such as supernovae, star clusters, and nebulae.
What is contained in a galaxy?
A galaxy contains billions to trillions of stars, along with gas, dust, and dark matter. It also includes planetary systems, stellar nurseries, and various types of celestial objects like planets, asteroids, and comets.
The Milky Way galaxy contains instellar matter may?
The Milky Way Galaxy contains interstellar matter that may form new stars.
Why do astronomers theorize that most of the matter in galaxies and clusters of galaxies is dark matter?
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

What do you know about dark matter?
Astronomers can infer the mass of a galaxy from the rate at which it rotates. The visible, glowing matter in galaxies (i.e., the stars) do not account for the amount of matter which we know must be there, hence we conclude that there is some additional matter which we do not see because it does not glow, or in other words is dark. Beyond that, we don't know very much about dark matter.

What is thev connection between universestar and galaxy?
The universe comprises all matter in space. This includes a very large number (200 billion to 2 trillion) galaxies. Each galaxy comprises a very large number of stars: our contains 100 thousand million stars.
What is in the Andromeda galaxy?
The Andromeda galaxy contains an estimated 1 trillion stars, along with gas, dust, and dark matter. It is also home to various types of celestial objects such as supernovae, star clusters, and nebulae.
Why do astronomers think there is dark matter in the universe?
That is because the dark matter attracts normal matter through its gravitation.
Why do astronomers study the sun?
There is an very dangerous matter in the sun named Black Matter. If the astronomers can get some of that matter, they can let a rocket fly to Jupiter and the austronauts will survive. Excuse me if my English is bad, I'm Dutch.:D
