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!

2,392 Questions

In what constellation is the center of the galaxy?

Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.

How many years would it take a spacecraft traveling at the speed of light to cross the milky way galaxy?

The very fastest human-made spacecraft ever aren't out of this solar system yet, and they were launched in the 70s.

"Billions of years" is, if anything, an understatement.

Is there more galaxies in the world or more grains of sand on a beach?

in the world, there are zero galaxies, so the answer is grains of sand.

if your actual question was about the number of galaxies in the universe:

there are more galaxies in 1% of 1/10 of the visible sky than on all the beaches of all the worlds oceans

What population stars are found in a sprial galaxy?

Population I (High metal content) stars are generally found in the arms of spiral galaxies, whereas population II (Medium metal content) are generally found towards the centre of the galaxies.

How many players is Mario galaxy 2?

Super Mario galaxy 2 can be played as a 1 or 2 player game.

You can play with 2 players simply by plugging in another wii remote. When you play with 2 players, player 1 steers Mario, and the other a luma. The luma can stop enemies in their tracks and then spin to make them fall over. Player 2 can in addition pick up coins and starbits. Also if both players point at Mario at the same time and press the A button at the same time, he does a super jump.

What is the closest spiral galaxy to the Milky Way Galaxy?

The closest galaxy to our galaxy the Sagittarius galaxy but its Dwarf Galaxy, Andromeda is the Complete Galaxy and yet classified as the Galaxy which is closest to our galaxy. Facts : There are 12 Dwarf galaxies and 1 complete galaxy within the distance of 500,000 light years. Andromeda Galaxy is moving towards our galaxy at the speed 300,000 Kilometers per hour, but its so far that i would take millions of year to have a clash.

What is the magnitude of a galaxy?

The magnitude of a galaxy will depend on a lot of factors, luminousity, size and distance from us.

The apparent magnitude of the naked eye galaxies are:

  • Large Magellanic Cloud +0.9
  • Small Magellanic Cloud +2.7
  • Andromeda Galaxy +3.4
  • Triangulum Galaxy +5.7
  • Centaurus A +7.8
  • Bode's Galaxy +7.89
  • Sculptor Galaxy +8.0
  • Messier 83 +8.2

Is it true that in the milky way it is a member of the local group?

The Milky Way Galaxy is the second largest galaxy, after Andromeda, in the Local Group. The Triangulum Galaxy (a.k.a., the Star Wars galaxy) is the third largest.

The Local Group contains about 30 galaxies, including dwarf galaxies.

Why are some stars in the middle of galaxies and are on the outside?

Stars in the middle of galaxies are usually found in the galactic disk, where there is a higher concentration of gas and dust that is conducive for star formation. Stars on the outside of galaxies are often located in the galactic halo, which is a more diffuse region that contains older stars and is further away from the dense center of the galaxy. The distribution of stars within a galaxy is influenced by factors such as gravitational interactions and the history of star formation in that region.

What date was earth created?

it has existed since the beginning of life no one crated earth as far as we know it.

Scientist believe that the more distant galaxies are formed when?

Far or near, all galaxies were thought to be formed in the first half billion years of the formation of the universe ... that is, about 13 billion years ago.

Note that we're seeing the distant ones in a younger stage of development.

Who were Andromeda's parents?

Andromeda was the daughter of Cepheus and Cassiopeia in Greek mythology.

What planets stars comets are in Galaxy NGC 3370?

NGC 3370 is a barred spiral galaxy in the constellation Leo. It contains stars, gas, dust, and possibly planets within its structure. Comets are not typically found within galaxies, but rather in the outer reaches of the solar system.

Why does mass have gravity what causes it?

The teacher's manual answer is that mass warps space. But the real answer is "Just Because" it's what mass does. == It's interesting in this day and age when we're on the threshold of discovering the very basic nature of the universe by virtue of our understanding of matter and spacetime that we don't know more about gravity. For as long as I can remember, the best answer for the question "what is gravity?" is this one: We don't really know. It's still true. Accept it. Say it with me: we don't really know. See? It didn't stop working just because we made that admission. We know what gravity does. There is a wonderful history associated with its quantification. We can sure measure its effects, can't we? Those elegant sets of calculations for, say, the music of the spheres, are nothing short of breathtaking. But what is it that is accessible to the rest of us that lets us get a handle on gravity? There really isn't too much. Let's review. Matter has mass and occupies space. By virtue of just existing, matter warps spacetime. It puts a dent in it. But that doesn't provide too much extra help. Spacetime is (hold on to your seat) a mathematical construct. Darn it! That ain't any help! Perhaps an experiment would help. Try something that's been passed along to teachers here and there. The necessary equipment list includes a bed sheet and two modestly heavy balls like croquet balls. Lighter balls like tennis balls won't work as well, but a bit of creative thinking and experimenting will allow one to make a good substitute for the wooden spheres. Four students hold a bed sheet by the corners and stretch it out. Hold it steady! Put a ball in near the middle. See the dent? That's what mass (the ball) does to spacetiime (the sheet). This is a two-dimensional model, but it is really quite good. Now add the second ball near the first one. (A bit of practice might be required because there are limits on what the bed sheet will allow. Try short sheeting the setup from one or from two adjacent sides.) The second ball makes a dent like the first one, but the space between them is deformed, and the balls will roll together. If they are placed too far apart, the demonstration breaks down, but that's where the practice comes in. Lastly, it's absolutely wonderful and exciting that we don't know more about gravity! We know all this other stuff. All this other science and technological stuff. And yet here is gravity! It is so big, so broad in its effect, that it is the large scale organizer of the whole universe itself! We have spent our entire lives in it, and we react to it without thinking when we move. And yet it stands in defiance of our understanding! Hey! Anybody wanna Nobel prize? Wanna become world famous? Wanna have hotties asking you for your phone number? We have this little problem that needs solving....

What galaxies are nebulas found?

Nebulas are found in all types of galaxies, including spiral galaxies like the Milky Way, elliptical galaxies, and irregular galaxies. They are regions of dense dust and gas where new stars are formed. The variety of shapes and sizes of nebulas contribute to the diversity of galaxies in the universe.

Is the leopard nebula real?

In astronomy - there does not appear to be a nebula with that name.

Other options could be:

  1. The Green Leopard Plague which won the nebula awards.
  2. A fictional wallpaper made with photoshop and used in Mac OSX

What is A PERSon who studies planets and galaxys?

A person who studies planets and galaxies is called an astronomer. Astronomers observe and analyze celestial bodies such as planets, stars, and galaxies to understand their composition, behavior, and evolution. They use telescopes and other instruments to gather data and make scientific discoveries about the universe.

If the Sun and Earth were at the edge of the disk of the Milky Way Galaxy what would be the diameter of the galaxy in light years?

The diameter of the Milky Way galaxy is about 100,000 light-years. If the Sun and Earth were at the edge of the disk, we would still be within the galaxy's boundaries, so the diameter would remain around 100,000 light-years.

Is a solar system smaller than a galaxy?

Galaxy. Solar system contain planets and stars. While thousands of stars makes up a Galaxy
A Galaxy.

Our Milky Way Galaxy is ~100,000 light years across.

Our Solar system is a mere ~0.005 light years across.

What do comets have in common with earth?

Both comets and Earth are celestial bodies located in our solar system. Comets are composed of ice, dust, and rocky material, similar to the materials present on Earth. Additionally, both comets and Earth experience gravitational forces from the sun that affect their orbits and movements.

What will happen AFTER 2 galaxies collide?

They can merge, to combine into a single, larger, galaxy. Or, they can separate again.

------------

"Collide" is a misnomer because of the vast distances between stars in a galaxy, the odds of a stellar collision are extremely small.

The Andromeda Galaxy and the Milky Way Galaxy are on a collision course. If you're around when they begin to "collide" in about 4-Billion years, don't expect to see any fireworks in the sky. Except for an increase of the number of observable stars in the night sky, it will largely be a non-event.

Does 6 go into 70?

No, although it could be recognised as going in 11 remainder 4 times, or 11 and 2/3 times

Do galaxies at very large distances look distorted?

Yes, galaxies at very large distances can appear distorted due to gravitational lensing effects caused by the bending of light by massive objects. This distortion can elongate or warp the images of distant galaxies, altering their perceived shapes.

If some of the galaxies in this image are 10 billion light years away what does that mean you are actually looking at when you take a picture of those galaxies?

You are looking at the light that that star made 10 billion years ago. Since it takes that many years for the light to reach earth, you would not notice if that star died for 10 billion years, just like you wouldn't notice by looking at it that the sun suddenly died for 8 minutes (The amount of time it takes for its light to reach the earth). We are constantly looking at the sun 8 minutes ago!
