Galaxies

Galaxies are large systems of stars and interstellar matter, and they contain billions of stars. Our own galaxy, the Milky Way, has 200 to 400 billion stars, and there are over one billion known galaxies. Questions that have to do with galaxies in general and specific galaxies are perfect for this category!

What are 2 ways in which galaxies can differ from one another?

Constellations are patterns of stars that we see in the sky. There are 88 official constellations, like Leo, Orion, Taurus etc. We are in the galaxy called the Milky Way, as are all the stars you can see in all of those constellations. A galaxy is a massive collection of stars. We can see some other galaxies, such as Andromeda, but they just look like a clump of dust in the sky because they are so far away, and we can't pick out individual stars.

Which is the best monster galaxy moga?

i think it is yugel bcoz people think winja is only having regroth ability and no other but i have found by evolving colibri that yugel also has his special ability as regrowth

What are the different group of stars?

While some people may call them star clouds, other use the term star clusters. They refer to the same group of stars.

What galaxy is the closest large galaxy to the milky way?

The nearest galaxy is Andromeda, which is predicted to collide with the Milkey Way, our galaxy, in billions of years.

What occurs in HII regions of the galaxy?

From Wikipedia: "An astronomical body's Hill sphere is the region in which it dominates the attraction of satellites." In other words, any object (such as a star, or a small galaxy) within a galaxy's Hill sphere can have a stable orbit; the orbit of anything outside of such a Hill sphere will eventually decay; in other words, it might escape, or fall towards the galaxy.

How big is an average spiral galaxy?

Our own galaxy, the Milk Way, is a spiral galaxy. It is 100 000 light years in diameter and 1 000 lightyears thick. Andromeda, the biggest spiral galaxy in our local group is in 220 000 lightyears in diameter

What is the closest galaxy near to earth?

What made galaxies?

Galaxies are formed when the gravitational pull comes together pushing stars in. Since black holes were extremely commmon at the birth of the universe, many galaxies own one, such as ours, the Milky Way. Galaxies such as the Sombrero and Andromeda have similar Holes. These holes are supermassive holes, giant gravity balls.

Do galaxies change over time explain your answer?

it changes overtime with constant movement and change in rotation

How does the Milky Way looks like?

They differ. Galaxies basically fall into 4 categories, those being Spiral, Barred Spiral, Elliptical and Erratic.

The sparse area surrounding a spiral galaxy is called?

Halo is the name given for a sparse area in space that surrounds a spiral galaxy. This type of galaxy has special constellations.

Does aliens exists in the galaxy?

I STRONGLY believe the existence of extraterrestrials. I mean, if you look at the stars, there has to be something orbiting around them. What if something lives on those planets? I have no doubts at all that we are not alone.

What is the hottest thing in the galaxy?

This is hard to answer. We don't really know

all of the stars but blue&white stars are VERY VERY HOT.

The strongest would be one of the super

nova stars. One of them is called the Orion. The

Orion is a white dust star. Dust clouds have sat in

it for over 1,000,000 years. It's the strongest star we know

in our galaxy.

In the Milky way galaxy (Solar System) , many people

think the sun is the hottest star. It is the most powerful

star in the Solar System, it gives us light and energy, but

thats because it is so close to us.

There is an exploding star as we speak, called Eta Carinae. It has burned/exploded for over 375 years. It could blow itself to bits at any time.

In which direction are nearly all galaxies moving relative to earth?

they are moving in all directions away, toward, sideways relative to EarthNearly all galaxies are moving away from the Earth. This is because the universe is expanding.

Is a farther away galaxy from us moving away faster?

Yes, furthest the galaxy more it's speed of moving away from each other also universe is expanding continuously therefore space between galaxies is also expanding . Redshift is directly proportional to the distance b/w the galaxies therefore distant galaxies red-shifted at faster rate

What are the 4 main galaxy shapes?

There are various ways of categorising galaxies, often based on Edwin Hubble's work on the shapes galaxies. Classifications often give the four main types of galaxies as: Spiral (including barred spiral), Elliptical, Lenticular and Irregular.

Speed of revolution of milkyway galaxy?

We can't really say, as we have to point of reference to be moving from. There are calculations on the order of 570 kilometers per second, but these are meaningless without a fixed reference.

The furthest galaxies we can see are moving at a high percentage of the speed of light relative to us, so we're moving that fast from their perspective.

How many suns are in a galaxy?

Our sun is one of between 200 and 400 billion stars in the Milky Way galaxy. There are literally untold billions of galaxies in the observeable universe.

Our sun is just another star among billions of billions other stars. Some of which are known to have planets orbiting them.

How did the Milky Way galaxy get named?

The Ancient Greeks - to them it looked like a stream of milk splashed across the sky.

What galaxies are 37 million light years from Earth?

The Sunflower Galaxy (M63 galaxy) and the Whirlpool Galaxy (M51 galaxy).

How many galaxies have you discovered?

personally i have discovered about 21 but im still workin on findin more

How many planets does our galaxy have?

One. The Milky Way is our galaxy. Every star you see in the sky at night with your naked eye is in the Milky Way. The closest galaxy to ours is the Andromeda Galaxy, which you can see if you look in the right place, but it will just look like a fuzzy blob and not like a star. The milky way is the name of our galaxy, there are no other galaxies in it.
