Messier 81 (M81), also known as Bode's Galaxy, is a spiral galaxy located approximately 12 million light-years away in the constellation Ursa Major. It spans about 90,000 light-years in diameter. This makes it one of the larger galaxies in the Messier catalog, comparable in size to our Milky Way. M81 is notable for its bright core and prominent spiral structure.
Considering the size of the Milky Way Galaxy and the amount of "empty" space, the amount of space an emission nebula occupies is so small as to be infinitesimal and impossible to equate to a volume.
The Andromeda Galaxy is 12,904,531,200,000,000,000 miles away and the space shuttle orbits at 18,000 mph so to travel to the Andromeda Galaxy in the space shuttle would take 81.8 billion years which is around 18 times the currrent age of the universe!!!
Yes, scientists can look at space and take pictures of it.. the first time this happened was in the mid 1960's when the voyager was launched. It sent back picture's of space to Earth.. almost half a century later it has final reached the edges of our milky way and take pictures of beyond.
lots
A space shuttle has never left the galaxy and never will. However, theoretically it would take a space shuttle an unimaginable amount of time to leave the galaxy. (I'm sure someone can provide a more precise answer).
i would have thought it was conciderably smaller because the space ships crosed it(at light speed) in minutes. if you tryed to cross our galaxy at light speed it would take billions of years.
they don't take any space up
not much :p
Not much to be honest.

If you take 10 tennis balls and spread them across the U.S. they'd be more crowded than the starn is our galaxy!
