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!

The only galaxy which we know for certain supports life is the Milky Way galaxy.
What happens when two spiral galaxies collide with each other?
You tend to end up with irregular galaxies
Vapor, mist, or fog is one set of English equivalents of 'nebula'. Nebula itself is another equivalent. It's an English derivative of the same original, classical Latin word of the ancient Romans.
Is the milky way pink and purple?
We have no way of taking a picture of it to say for sure, but there's probably a mathematical and logical way to determine the overall color scheme of our galaxy.

What is the shape of andromedas constellation?
The Andromeda constellation takes the rough shape of the English alphabet letter "A."
Yes. If the photons have travelled 10 billion years, that means you are seeing the galaxy as it was 10 billion years ago.
When stars form they are mostly made up of hydrogen.
Main sequence stars derive their energy from converting hydrogen in helium in the cores. As the star ages the ration of helium to hydrogen increases. A star with a lot of helium there for must be old.
When the hydrogen has exhausted in the core the star begins to collapse due to gravity until it reaches a point that the temperature of the core is sufficient to fuse Helium into Carbon.
Why was your galaxy named after milk?
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!
What is the setting of hichhiker's guide to the galaxy?
The settings vary as the book/film progress. It starts on Earth and gradually the rest of the Universe gets involved. The planets that Ford and Arthur visit are places like Magrathea, Kria and Viltvodle VI. They also spend a lot of their time on the Heart of Gold (a stolen spaceship) ...
Is it possible for people to go to the Andromeda Galaxy?
No. With current technology we can't even go to the nearest stars (outside our Solar System), the Alpha Centauri system.With some hypothetical technology it MIGHT one day be possible, for example, to reach 1/10 of the speed of light - though even that is science fiction for now. At such a speed, it would take over 40 years to reach Alpha Centauri; and 25 million years to reach the Andromeda Galaxy.
But if you wait 3 or 4 billion years, the Andromeda Galaxy and the Milky Way will join.
The law is called The Inverse Square Law .
What is the relationship of planets and stars with solar system galaxies and the universe?
Most planets orbit stars forming stellar systems. Stars are not part of the solar system which is simply the stellar system for our star - otherwise known as the sun. Stellar systems together form galaxies and these form a part of the universe.
Is it the most distant dwarf galaxy when it's 13.1 billion light years from Earth?
Yes, it's the most distant dwarf galaxy 13.1 billion light-years from Earth (i.e. MDC2010 1721 in the Hubble Ultra Deep Field).
The "redshift" refers to the fact that the light is less energetic than when it was emitted; it shows that the galaxies move away from us. Should a galaxy move towards us - which is possible only for galaxies that are relatively close to us - then there would be a blueshift.
What galaxy contains dust gas and younge stars?
Almost all of the galaxies have dust in them, most have new stars, but I think you are thinking of the Horse head nebula which is cited as a stella nursery.
