How is the Milky Way galaxy classified?
The universe is the entire region of space from which light has had time to travel since the instant of the big bang. The universe consists of a hierarchy of natural structures. Simple, cohesive structures bound together by gravity include the planets and stars. At larger scales, vast aggregations of matter include the galaxies which are enormous gravitationally-bound stellar populations. Most astronomers believe that there is more matter than what we can observe.
Why do they call it the Milky Way galaxy?
cause of the depth of the water is what makes the color of the ocean along with what lies underneath it, the Palau Milky Way is not sand, it's white limestone mud. white limestones are free from impurities, but they generally contain small quantities of other minerals than calcite which affect their color. Many limestones are yellowish or creamy, especially those that contain a little iron oxide or iron carbonate or clay. They call it Milky Way because it is the color of Milk.Sciencetist call our galaxy the milky way because in the past,when they looked in our galaxy it was all white like milk.
How many stars in Mutter's Spiral?
There are estimated to be about 250 billion stars in the Milky Way galaxy, which is part of the Mutter's Spiral.
The "AU" ... astronomical unit ... is the average distance between the earth and sun,
roughly 93 million miles.
The diameter of the planet Mars is roughly 4,200 miles, or 0.0000452 AU.
The semimajor axis of Mars' orbit is about 141.6 million miles, or about 1.52 AU.
What is the most common way mountains form?
Mountains most commonly form through tectonic plate movements, specifically at convergent plate boundaries where two plates collide. This collision can result in the plates pushing against each other, causing uplift and the formation of mountain ranges. Additionally, volcanic activity can also contribute to the formation of mountains.
A star is made of gas What forces hold a star together?
That is still a mystery. Obviously, they are held together by gravitation. Each star attracts each other star, and you might say that the combined force of these attractions keeps the galaxy together. But the known matter in our galaxy - and in other galaxies - isn't strong enough to account for the fast rotation a galaxy has. There must be about 5-10 times more matter, compared with known matter, in something invisible - commonly known as "dark matter". This mysterious dark matter can be noticed through its gravitational attraction, but it can't be seen directly.
Which way do the planets orbit the sun?
Just about everything in the solar system spins the same way. If we could sit high above the "north" pole of the Sun and watch (and if we could see anything!) we would see that almost everything spins counter-clockwise. All of the planets and asteroids orbit that way, and most of the planets rotate that way as well. For the few that don't, we call the rotation "retrograde".
It is difficult to know for certain, but the most likely explanation is that this was the way the planetary nebula was spinning when it all came together from gravitational attraction 5+ billion years ago, before the Sun was born.
Is milky way galaxy a homogeneous mixture?
False. The Milky Way Galaxy, our Solar System and the Universe itself are composed of a mixture of known and unknown elements, and light & dark matter. By definition this makes the Milky Way, and the Universe heterogeneous by definition.
What happens to the pitch of sound if the box is elongated?
If the box is elongated, the pitch of the sound decreases. This is because the elongation increases the length of the vibrating medium, resulting in a longer wavelength and lower frequency, which is perceived as a lower pitch.
There are more spiral galaxies than elliptical?
the elliptical galaxy has a round or oval shape the spiral galaxy has a hurricane shape
The origin of these different shapes would lie in the particular momentum of the constituent stars at the time they first coalesced into a galaxy under their mutual gravitational attraction.
Which galaxy does the sun belong to?
These are the basics. Our sun is the star at the center of our solar system. A solar system is made up of a star and any other objects connected to it by its gravity. Our sun has the standard eight planets along with their moons, and also countless other objects including asteroids and comets. Our galaxy, The Milky Way, is estimated to contain between 200 billion and 400 billion stars. Some of those stars have planets orbiting them, and others do not. Our solar system then is just a very very tiny part of the Milky Way, and the Milky Way is one of billions of observable galaxies throughout space.
Why is it difficult to specify the dimensions of the disk and halo of the Milky Way?
Imagine that you were inside a large office building. Quick, what does it look like from the outside? That's basically why. While nearly all the individual stars we can see are in the Milky Way galaxy, we can only see a small fraction of them and being inside it, with dust clouds getting in the way (we can't even see, visually, the center of the galaxy, because of all the dust), it's kind of hard to tell what the overall shape is.
Now, to put things into perspective: when we say that we're "not certain" of the shape, what we really mean is fine detail. Just as if you were in the central courtyard of the Pentagon, you could be pretty sure that the building is pentagonal, the chances of the Milky Way NOT being a spiral galaxy are so close to zero as to be indistinguishable from it in any practical sense, and we're pretty sure it's a barred spiral. Exactly how many arms and how many times they wrap around ... that we can't really tell, but the gross structure is pretty nearly a dead lock.
Why might you find the Milky Way Galaxy more prominent in July than in January?
In July, the Milky Way Galaxy appears more prominent in the night sky in the Northern Hemisphere because it is summer, and this season offers better viewing conditions with darker skies and fewer clouds. In contrast, in January, the Milky Way is less visible in the Northern Hemisphere due to winter conditions when nights are longer, and there may be more light pollution and cloud cover obscuring the view.
The Winchester model 59 is not a gas operated semi-auto, instead it uses the short recoil system and hence their is no adjustment. The model 59 should be able to shoot trap loads without any adjustment if working properly.
Is the solar system located outside of the Milky Way Galaxy?
NO!!! The Sun and its Solar Sytam are located in one of the 'tails' of the Milky Way Galaxy.
The Milky Way Galaxy it like a giant Catherine Wheel, with a bright core and two curved tails. The whole of which is rotating. We are in one of those curved tails.
What does the milky way galaxy orbit and how long does it take?
The Milky Way and the Andromeda Galaxy are the two giants in our local group. These two galaxies will collide, but neither one can be said to orbit the other. In some instances smaller galaxies might "orbit" a giant cluster, with periods measured in billions of years. Galaxies in general do not orbit anything. Instead they are all simply spreading further and further apart as the universe expands.
Is the Vega star in the milky way?
Yes it is. All the stars that we can see are in the Milky Way galaxy. Stars in other galaxies are too far away from us to be able to see them properly. That is even true of many stars in the Milky Way Galaxy.
Why is milky way galaxy called akash ganga?
Milky Way looks like a river from earth. In Hindu mythology thus it is called akasganga.
