We don't know. The diameter of our galaxy is estimated at 100,000 lights years. But it is an estimate. When we look at the stars in the night sky, we are looking at how those stars were thousands, even hundreds or thousands of years ago.
AU is short for astronomical unit. It is the distance from the Earth to the sun or 93 million miles. It is used for inter solar system measurements. The light year is used for galaxy to galaxy measurements. See the related link for more information.
Both subcontinent and galaxy are common nouns, words for any subcontinent or any galaxy of any kind.A proper noun is the name of a specific person, place, thing, or a title; for example:The Indian Subcontinent or the Arabian Subcontinent.Committee for the Arts of the Indian Subcontinent, San Diego, CA"Gothic Alaskan and Other Stories: Bad Horror from the Dark Subcontinent" by B.J.

The creek will serve as a boundary for our garden. The path of the Voyager spacecraft will take it right past the boundary of our galaxy.
No one lives in the Galaxy itself.. but the worlds in it.. and at the moment the only world with life as we know it is us... and there's about 6,775,235,700 in the world.. that's from 2009 so I would say that...Hope this helps(:
Population 1 stars are luminous. They include the Sun and are hot and young stars. These types are usually found in spiral galaxies. Population 2 stars are found in nucleuses of galaxies and globular galaxies. These stars are older and usually cooler than the population 1 ones.
It is 2.4*1019 kilometres away.
This can be expressed as: "The Andromeda Galaxy contains at least 2 x 1011 stars".
The nearest and the largest galaxy to the Milkyway is the "Andromeda Galaxy."
As far as we know, we only use scientific notation here on Earth, for the computing of very large numbers (like the distance between planets) or very small numbers (like the radius of a hydrogen atom).
Not counting the Magellanic Clouds (which are minielliptical galaxies orbiting our galaxy), the Andromeda galaxy is the galaxy nearest to our galaxy.
because when you are working with large numbers, scientific notation is much less prone to error. Writing the size of the galaxy in miles for instance, the galaxy is approximately 6,000,000,000,000,000 miles across. writing that in scientific notation is much neater, and easier. 6.0 x 1015 So it saves a lot of time and effort, and is a lot easier to be sure you are being accurate.
The nearest Spiral Galaxy is our own Milky Way Galaxy. After that, is the Andromeda Galaxy.
The nearest non-dwarf galaxy is the Andromeda galaxy.
Our galaxy, the Milky Way, has a diameter of about 100,000 light-years.
The dwarf galaxy is about 8,000 miles in diameter.
An average dwarf galaxy is small in diameter.
The average diameter of a dwarf spheroidal galaxy is 10 kiloparsecs.
