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!

Do galaxies shift near or far away from earth?
Most galaxies have a red shift away from us - meaning they are moving away from us. However, the Andromeda galaxy has a blue shift, which means it is moving towards us. In about 2.5 billion years time, the two galaxies will merge.
How far away are the most distant galaxies?
That is impossible to answer because scientist don't know ALL the galaxies.
When will the Milky Way galaxy die?
in about 5 billion years when the adromeda galaxy collides with the milky way
btw the adromeda is bigger than the milky way, about 1/2 larger
CRAP SAUCE!!!!!!!
Can treads on spiral staircases be rectangular?
Yes, if the spiral is rectangular with a core and the corners are square landings. If the spiral is circular, then obviously no.
Does a massive elliptical galaxy have a lot or very little gravitational force on other galaxies?
Massive means there is a lot of mass - and gravitational attraction depends on the amount of mass. The amount of gravitational attraction also depends on the distance - i.e., the effect will be less at larger distances. The gravitational attraction between galaxies is strong enough to make galaxies in a galaxy cluster stay together - for example, in our Local Group.
An unimpressive medium sized star in a remote portion of the milky way?
That might refer to our Sun. Or to any of several billions of other stars.

Why are galaxy collisions of interest?
They create larger galaxies. Sometimes they can make mysterious celestial happenings....
Is there anything past this universe?
Scientist speculate there may be theoretically, but there is no evidence that there is any universe other than this one.
Which is the nearest planet to the milky way?
All of the 1000 or so planets discovered so far, or most of them, are inside the Milky Way.
Yes, quasars are the most luminous objects in the universe.
There is no definite answer. You can assume that you have not already died and deduct those days between your birth and now from the when list. You can assume that you will not live to an age any greater than 120 .. all days after that are off the list as well.Statistically you can visit several sites and charts which pose questions like do you smoke, do you have diabetes, are you a drug mule, do you live in North Korea as a political dissident. This will establish your estimated life expectancy range. Life insurance companies use this data in determining your personal chances for a longer or shorter life. None of this will give you a definite death date.
Alternately you can think on the fact that the Universe has been here for 15 billion years when you weren't here and will be here for at least that long without you after your dead. As a fraction of the time your 120 years or so is pretty insignificant. Enjoy what you get.
Is galaxy the same as Milky Way galaxy?
No. There are many galxies, but only one of them is the Milky Way Galaxy.
Does the Milky Way galaxy have an atmosphere?
An atmosphere occurs when gases are held in a gravitational field by a body. The Milky Way is a galaxy not a planet or star and does not have an atmosphere of its own.
What galaxies have a blue shift?
There are about a 100 known blue shifted galaxies.
The most well known, is the Andromeda Galaxy.
