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 other solar systems are in the milky way besides ours or is it the only solar system?

Yes - If we define a 'solar system' as a star ('sun') with its associated planets and other objects in orbit around it. The Milky Way (our galaxy) consists of thousands of millions of stars - of all sizes, temperatures, colours etc. For some years now astronomers have been observing some of these stars, and by various techniques (using delicate and sensitive measurements) they have now discovered hundreds of planets orbiting many of the these stars. Most of these were like Jupiter - large gas giants - but this type of planet would be much more likely to be discovered because of its size and mass. However, more recently smaller planets - more earth like - have been discovered too. So, many solar systems have been discovered in the Milky Way. If we reaise that, like our own galaxy, the Milky Way, there are thousands of millions of whole galazies out there each with thousands of millions of stars - so the possibilities of them having their own systems is very very high. Astronomers now believe that solar systems are the norm rather than a rarity.

How many au is the sun from the center of the Milky Way Galaxy?

An AU is the wrong measurement, that's like asking how far it is from London to New York - in millimeters.

An AU is merely the average distance from the Sun to the Earth, some 50 million km. The Milky way is about 100,000 Light years in diameter - a light year is about 10 trillion kilometers (10^16km = 10,000,000,000,000,000km).

Since we are on the outer edge of one of the spirals, make that 50,000 light years from the Sun to the center of the Milky Way. So if my math is right,

(50,000 * 10^16 )/ (50 * 10^6)

= (5 * 10^20) / (5 * 10^7)

= 10^13 AU

What galaxy don't have a distinct shape and are not symmetrical like spiral or elliptical galaxies?

Irregular galaxies do not have a distinct shape or symmetry like spiral or elliptical galaxies. They often appear more chaotic and disordered, lacking the structured appearance of other galaxy types. Irregular galaxies can vary greatly in size and are characterized by a less defined structure.

How many years until the Andromeda and Milky Way galaxies collide?

There are 2 much smaller irregular galaxies that orbit our galaxy called the Magellanic Clouds. These are abbreviated LMC and SMC (large and small Magellianic Cloud). These will one day gradually collide with The Milky Way but it is a long time until that happens; no need to worry. There is also the Andromeda Galaxy which is on a collision course with us.

What is a galaxy How many galaxies are there and how many stars does each galaxy hold?

A galaxy is a large system of stars, gas, dust, and dark matter held together by gravity. There are estimated to be billions of galaxies in the universe, each containing millions to trillions of stars. The exact number of galaxies and stars in the universe is still unknown due to the vastness of space and the limitations of current technology.

Will Earth ever fall into the black hole at the center of the Milky Way Galaxy?

No, Earth will not fall into the black hole at the center of the Milky Way Galaxy. The black hole is located about 26,000 light-years away from Earth, and our solar system is orbiting it at a safe distance. The gravitational pull from the black hole is not strong enough to pull Earth into it.

Who is galaxy leon?

galaxy leon is a beyblade. that has galaxy pegasus energy ring and leons other parts.

Is your galaxy bigger than a black hole?

Yes, a galaxy is typically much larger than a black hole. Galaxies can contain billions to trillions of stars and vast amounts of gas and dust, while black holes are typically formed from the remnants of massive stars with a gravitational pull so strong that not even light can escape from it.

What do astronomers use to map the shape of the Milky Way?

Astronomers use radio telescopes, infrared telescopes, and space-based telescopes to map the shape of the Milky Way. They measure the positions and motions of stars, gas, and dust to create a three-dimensional map of our galaxy.

How many double planet systems are in the solar system?

There are no double planet systems in our solar system. The closest to being considered a double planet are Pluto and its largest moon Charon, but since Charon is significantly smaller than Pluto, it is not classified as a double planet system.

What makes quasars Different From other stars?

A star is matter being compressed (by the force of gravity) wich in turn heats the star and is the mechanism for Nuclear Fussion, subsequently the star expands ( gravity vs. heat). A Quasar on the other hand is not a star at all, it is, in fact dust wich is being pulled towards a Supermassive Black hole (usually at the center of a Galaxy), the dust being Super-accelerated, and rubbing (friction) against other particles, heats up to an incredible temperature and emits extra-ordinary bright light, which we have come to know as Quasars (accretion disc of dust around Supermassice Black hole)

How far is the sunflower galaxy?

The Sunflower Galaxy (M63, or NGC 5055) is a spiral galaxy in the constellation Cane.

It is approximately 37 million light years from us.

Where do scientists believe that our solar system is located in our galaxy?

We (and the sun) are on a far arm of the Milky Way Galaxy. If you look up in the sky on some clear nights, you can see an almost greenish cloud-like mass. That's the rest of the Milky Way Galaxy. Since we're out on a limb, we can see the rest of it. If that doesn't make sense, think of it this way- If you are at the top on the far west side of a football stadium, then you can see the whole stadium, top and bottom, in a pretty much unobstructed view. That's about where we are in the galaxy. Of course, we are constantly spinning and moving, but we'll be in the same relative place for quite a while.

When is the Beyblade galaxy pegasus comin out?

Tus is the hasbro version. It should come out in about May. If you want to preorder it go to toywiz.com anf click on beyblades then single packs. Then scroll to the bottom it will show all the pre orders

The takara tomy version already came out you can also buy galaxy pegasis from the same site

Is the Milky Way about 200 light years in diameter?

No, the Milky Way is much larger than 200 light years in diameter. It is estimated to be about 100,000-120,000 light years in diameter.

How do you get the hidden star in honeybloom galaxy?

you have to go on the swing right after the second mushroom-thing you swing all the way up, and spin Mario so that he gets on the wall. when you get to the top, there is a star waiting for you.

What could a solar system or galaxy and a microscopic ecosystem have in common?

Both a solar system/galaxy and a microscopic ecosystem are complex systems that involve interactions between various components. They both operate based on principles of interconnectedness and interdependence among their elements, leading to stable structures and behaviors. Additionally, they can both exhibit patterns of organization, such as planetary orbits in a solar system and trophic levels in a microscopic ecosystem.

What are stars mainly made up with?

When stars first form and fusion takes place the star is almost totally Hydrogen. During fusion it turns Hydrogen to Helium. Once all the Hydrogen is used up it will then start to fuse Helium and so forth and so on. Depending where in the life cycle the star is will denote its composition.

What have been the benefits to science due to the HST?

Improve

The benefits for science have been that we have seen further into space than ever before, we have looked at stars close up, we have given ourselves a bright future thanks to this telescope

Is dark matter related to antimatter in any way?

No, dark matter is entirely different from antimatter. For one, we know a lot about antimatter and have been able to do experiments with it and actually utilize it in some nuclear reactions.

Dark matter is a theory to help understand why the universe does not behaive the way we believed it should. Galaxies are showing that they do not have enough mass to have the gravitational effects that they do, so there must be matter somewhere, this is labeled as dark matter.

How many possible intelligent life forms in our galaxy?

It is difficult to estimate the exact number of possible intelligent life forms in our galaxy since it is based on hypothetical scenarios. The Drake Equation is a formula that attempts to estimate this number by considering factors such as the rate of star formation and the likelihood of planets hosting life in habitable zones. However, without concrete evidence, it remains speculative.

Is the milky way galaxy located 2.2 million light years from the sun?

No. Reach up and pinch your nose; that's part of the Milky Way you are pinching! We - each and every one of us here on Planet Earth - are as much a part of the Milky Way as one of your hairs is part of YOU. We're part of the Earth; the Earth is part of our solar system. This solar system, and every individual star you can see in the sky, are part of the Milky Way.

What determines the shape of a galaxy?

That is related to their past history. Many galaxies have undergone collisions with other galaxies; this takes out most of the interstellar gas, and the galaxies can no longer form new stars. If I remember correctly, such galaxies will change into elliptical galaxies.
