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!
First you have to prove a parallel universe exists. It is theorised that they exist, but it is not proven. If they do exist, it is doubtful we could ever go there. We are designed for this one, for the physical laws the operate here and if we did go there, we probably wouldn't be able to survive. A...
No , it is not a 'real' galaxy, merely one that exists inside the movie world. It is based upon Science Fiction, and you will not be able to travel to it.
Earths atmosphere consists of 78.09% Nitrogen, 28.95% Oxygen and 1%trace elements, mainly Argon. The martian atmosphere consists of96% Carbon Dioxide, 1.9% Nitrogen, 1.9% Argon, with oxygen presentonly as a trace element. Where you to inhale the martian atmosphereyou would suffocate. The atmosphere...
Quasars (Quasi-stellar radio source) emit billions [10 9 ] or even trillions [10 12 ] times the energy of a star in our galaxy, the Sun. Quasars show a very high redshift, which is an effect of the expansion of the universe between the quasar and the Earth. They are the most luminous, powerful, and...
We remain about the same distance during the entire galactic rotation (220 million years).
Scientists measured it in light years. The Milky Way takes 100000years to get from one side to the other at the speed of light.
The decrease is caused because it makes the spiral galaxy movefurther apart.
In the Northern Hemisphere from June through February
Galaxies occur solar systems that formed after the universe exploded.
It is our galaxy the Milky Way. If you go to the Local Cluster you can look at Earth and in Mass Effect 1 you have a mission on the moon (Luna).
yep, Earth: Milky way galaxy, saggitarius arm, sol, third orbit. :D all you need to do is ask a nerd :P
To keep the mood fun, ask questions about things which the person is interested in. For example, if they love watching pretty little liars, ask them who they think a is (bad example, sorry :P). If you don't know about their interests, ask them- e.g. 'whats your favourite tv show?'. Maybe you could...
Ah, a math quiz. If the nearest galaxy is 2000000 light years away then it would take 20 Milky Ways laid end to end to equal that distance. Now the problem is that Andromeda is the nearest spiral galaxy and it is 2.5 million light years away, so it would actually take 25 Milky Ways.
If you mean the distance then it's 50 thousand light years. Which is 2.95 × 10 17 miles.
The galaxy was named after milk because when early astronomers looked at the sky they noticed a band of stars that somewhat looked like milk!
That will depend on the speed. At the speed of light, it shouldtake about 26,000 years, since the center of the Milky Way is about26,000 light-years away from us.
Andromeda is the wife of Perseus and the only mother of hischildren seven sons: Perses, Alcaeus, Heleus, Mestor,Sthenelus, Electryon, and Cynurus as well as two daughters,Autochthe and Gorgophone.
Andromeda was a mortal princess of Eithiopia and later wife ofPerseus and queen of Mycenae.
No, the Koopa Kids don't appear in Galaxy 2.
Depends on how a galxy's size is compared to another one. Some galaxies are larger than others. But in light-year lengthwise, they are very big. A light year is equal to almost 6 trillion miles or 10 Pm (Petametre)
the answer to this question from the nasa website is 26,000 light years.
About 2.5 million light years from Earth, but since the Earth andSun are only 8 light minutes apart, there isn't that much of adifference in how far the Andromeda Galaxy is from the Sun orEarth. So the Andromeda Galaxy is about 2.5 million light yearsfrom the Sun and Earth.
Nebulae or star clusters within the Milky Way Galaxy.
If such an enormously expensive project were undertook, I'm sure it might be sold by saying that they'd carry everyone's eggs and sperm. However, what obligation the colonists would feel at the other end of the trip would be questionable. And there'd certainly be no way of enforcing it. I imagine...
The fuel is not a regular chemical fuel, but hydrogen, which gets converted to helium through nuclear fusion, at very high temperatures.\n\n The fuel is not a regular chemical fuel, but hydrogen, which gets converted to helium through nuclear fusion, at very high temperatures.\n\n The fuel is not...
Well, there is a way to be specific, but Astronomers estimate thatthe Milky Way contains up to 400 billion stars ofvarious sizes and brightness. Meaning, there are A LOT.
An irregular galaxy is a galaxy that does not have a regular shape, like a spiral or an elliptical galaxy. [1] The shape of an irregular galaxy is uncommon - they do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear...
Messier 87 is an elliptical galaxy.
A Glaxy is Samsung's electronic tablet answer to Apple's iPad.
Gravity is a field or a force, and, hence, has little to do withspeed.
I would say about 500 million light years
The Large Magellanic cloud.
There are two different ways in which a star can die, Firstly, small stars, they cool and become white dwarfs. Nothing spectacular. Secondly, large stars. This is more interesting. If a star is big enough and it forms a red giant, then there are two ways it can die. Firstly, the outer layer...
In our Solar System, that would be Mercury. (It used to be Pluto,but that one is no longer considered a "planet").
Estimates have tended to range between 300 billion to 400 billion.
Thousands of years ago, people saw the galaxy from Earth, and theythought it looked like a spilled carton of milk.
No. The world we live on is a planet. That planet orbits the sun,which is one of many stars in a spiral galaxy.
When you say "solar system", you're talking about all the millions of stones, meteors, comets, asteroids, moons, and planets that are gravitationally bound to the Sun, orbit it, and go wherever it goes. That entire family of millions of objects is contained in roughly 0.2% of all the space ...
ifyou are referring to any galaxy they are formed by exploding stars or something
Magenta with a hint of yellow.
That is because there is no oxygen in other galaxies and that we humans need oxygen to survive without it, we will die.... *plus, i am only p6 so it might not be accurate the other answer is kinda right but its really because its to far away and u wouldn't have any food or water unless u...
One of the earliest galaxies known to man is the galaxy IOK-1 and is estimated due to redshift to be 12.88 billion years old, only 750 million years after the Big Bang.
personally i have discovered about 21 but im still workin on findin more
Probably not. It requires a more massive star for a supernova. Of course, there is the possibility that our Sun somehow acquires a lot more mass, but this seems rather unlikely.\n Probably not.

Globular Clusters. They are thought to have stars as old as the galaxy itself.
One possible benefit would be to measure the amount of water that may be trapped in the permafrost. This information would be invaluable to scientists planning manned expeditions to the planet.
Only tides on Earth are called "high" and "low." But these occur when the tidal force is the strongest and the weakest, respectively. So the strongest possible tidal forces exist around black holes whose Event Horizon is very small.
You can find them on most nights depending on the weather and whathemisphere you're in.
I have no FREAKING idea this site it a waste of your time so dont ever use it agin or i will hunt u down wall ub sleep you hear me never use this site agin!have a nice day :D:D:D:D:D:D:D:D
We are part of the milky way galaxy, so we are moving with it.
Yes they do. See related question.
Yes. A galaxy contains many stars.
The very center is believed to contain a very powerful black hole.
No because if we wear in the middle of the galaxy everything wood spin around us.
There are planets within every galaxy, so yes
well....yes they could if we were that advanced. not yet but maybe in the future.
If you are talking about my mind probably 150,000 Lightyears across but if your talking about space probably 100,000 light years in this galazy
Yes. All the stars visible to the naked eye are in a fairly smallportion of our galaxy.
There are thought to be between 200 billion and 400 billion stars in our galaxy. So for every star, there could be several planets in orbit. This is just our galaxy though, there are then thought to be 100 billion galaxies or more, so total number of stars in the universe is massive.
In the center of every galaxy there is a giant black hole.
Elliptical galaxies, Spiral galaxies, and Irregular galaxies.
Well. The solar system from Mercury to Pluto is 32 years across. The solar system is full of stars and planets and it has the sun that also is a star that will burn into a red giant in just 4.5 billion years! and gobble up Mercury, venus and earth. The milky way is full of stars and is the main...
The galaxy clusters are the solar systems orbiting the galaxies.
220-240 million years.... Imagine how insignificant we really are. The last time our solar system was at the point were at now, dinosaurs just started roaming the earth. Our solar system orbits at 600,000 miles per hour
Yes, there are huge clouds of hydrogen gas, called nebulae.
The Milky Way Galaxy is classed as a spiral galaxy as it's appearance is of a spiral with looser outer stars becoming denser the closer you get to the centre. As a picture is worth a thousand of my words, the the related link for a generated picture of our galaxy. Note: This is a computer...
The Milky way, Our Sun is near the galactic core in the Orion arm,lets say ah, about 27,000 light years away.
100,000 Light Years = 6.32396717 x10^9(ninth power) au
if you were to look at the disc of the milky way the solar system is towards the outside of the disc, at a distance from the centre of about 80% of the radius.
None. P.S., Are you 5?
You are mistaken to think that Andromeda is a planet. It is in fact a galaxy located in the night sky in the constellation of Andromeda. The Andromeda Galaxy, also known as Messier 31 is the closest spiral galaxy approximately 2,500,000 light-years away.
Yes. The planet Venus orbits the Sun, just like Earth, Mars, Jupiter and other planets, comets, and asteroids. this is called the Solar system (The old name for the sun was Sol ... Sol-ar...Solar) Our star (the sun) and its planets are a very small part of our galaxy, which itself is composed of...
There are some red dwarf stars(dwarf ellipticals) in the Milky Way that seem to date back to about 1 billion years after the Big Bang.
That really depends on the exact interpretation of the term "discovered". We haven't actually sent probes (manned or unmanned), even to the nearest star - whose distance, about 4 light-years, is a trifle compared to the size of the galaxy (about 100,000 light-years in diameter). We do have a general...
There are a number of ways to count these - based on actual catalogs of the observed universe, based on estimates of the observed universe and based on estimates of the entire universe. The actual catalogs (there are numerous ones) have name around 10,000 galaxies. The best quantified amount is the...
The Milky Way Galaxy is about 100,000 Light Years across. Each light year is about 63,241 Astronomical Units. An Astronomical unit is the average distance between the Sun and the Earth, or about 93 million miles. Based on that math we form an equation. 100,000x63,241=6,324,100,000 Astronomical units...
It looks more like a gigantic disk, with a bulge in the middle.
No. The Milky Way is the galaxy of which our solar system is a tinypart.
About twice the size of the Milky Way, so about 200,000 light-yearsacross, so the Milky Way is 100,000 light-years across.
We don't yet know enough about dark matter - or even if it really exists - to be able to speculate on what "form", if any, it might take. You have to remember that "dark matter" is entirely theoretical, based on the supposed fact that the Milky Way doesn't have enough mass to keep it together,...
Yes, The Big Bang theory says all galaxies are moving outward and the universe is also expanding due to the explosion.
Well it depends what u mean because maybe its because you observed it in a large picture or u viewed it from above
We believe that the Milky Way is a barred spiral galaxy. Follow the link to see Hubble photos of other barred spiral galaxies.
I heard the ancient Greeks called our galaxy the Milky Way because they thought it was made from drops of milk from the breasts of the Greek goddess Hera... .
In fact, galaxies have an enormous mass. In fact, galaxies have an enormous mass. In fact, galaxies have an enormous mass. In fact, galaxies have an enormous mass.
The nearest and the largest galaxy to the Milkyway is the "Andromeda Galaxy."
The Andromeda galaxy is about 2.5 million light years away from theearth.
Michel Mayor, Dominique Naef, Francesco Pepe
the galaxies have different shapes.
