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!

How far is the Cartwheel Galaxy?
The Cartwheel Galaxy ( ESO 350-40) is a lenticular galaxy about 500 million light years away in the constellation Sculptor.
I never heard about an exploding galaxy. Perhaps you are confusing this with something else.
What galaxy is Alrisha in the constellation Pisces in?
All stars visible with the naked eye are in the same Galaxy. Our galaxy, the Milky Way.
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER
Edwin Hubble Classified the Galaxy different categories depending upon its visual appearance.
Which galaxy has a name starting with g?
The only one I know of is G350.1-0.3, It was thought to be a galaxy but turned out to be a supernova remnant.
When the sun runs out of fusion will this end of life on Earth?
Hell yeah it will. But that's not gonna happen for like another 5 billion years.
Long before the Sun burns out it will become a red giant star and engulf the earth, destroying all life on it. Presumably by that time the human race will have developed space travel and re-settled on other planets in the universe.
What galaxy does Proxima Centauri belong to?
It is the nearest star to our solar system an in the same galaxy as us, the Milky Way.
WHAT DOES AN IRREGULAR GALALXY LOOK LIKE?
An irregular galaxy looks sort of like clouds in the sky. A large part of an irregular galaxy is made of clouds of dust and fine rock. The Milky Way galaxy looks like a pinwheel, and some galaxies look like near-perfect discs.
Is the milky way tilted or horizontal?
You cannot truly say that it is either. Vertical and horizonal are relative terms. The Milky Way floats ins space, where there is not defined up or down, and therfore no horizontal or vertical.
What galaxy is the star Procyon in?
It is found in the constellation of Canis Minor, and is actually a binary star system. Like all the stars that we can see, it is in the same galaxy as us, which is the Milky Way.
How does the brightness of a quasar compare with that of a large galaxy?
I assume when you mean brightness, you mean apparent magnitude as opposed to absolute magnitude.
The quasar 3C 273 has an apparent magnitude of about 12.8 whereas the brightest galaxy - the Large Magellanic Cloud has an apparent magnitude of 0.9.
However, in absolute magnitudes, 3C 273 has an absolute magnitude of about -26.7 very similar to our own Sun.
Do galaxies emit light and why?
Well, you can see them, right? - Galaxies contain millions or billions of stars; each of these stars emit light.
The distance between objects in the universe are usually measured in light years because?
Astronomers normally use parsecs to define distance on a galactic scale. The definition of a parsec is quite difficult to visualise if you are not familiar with terms such as parallax and arcsecond. (The word parsec is derived from these terms; parallax arcsecond).
In contrast to this, it is easy to grasp the concept of a light year. It is the distance that light travels [in a vacuum] in one [Julian] year. This is why popular science articles tend to express distances in light years.
What galaxy is 60 light years away?
There is no such galaxy, the nearest galaxy is over 2 million light-years away.
6,300 years
What aspect of the "working" of the Milky Way are you interested in? The Milky Way is a galaxy - the galaxy we live in. It consists of several hundred billion stars, each a sun similar to our own Sun. It has a diameter of about 100,000 light-years.
What is the name of the north star that is on the end of the little dippers handle?
It is called "Polaris".
What is the Milky Way and when did it form?
It is a rather small, tasty, milky chocolate bar. They were first sold in 1932.
