How did Edwin Hubble determine that the Great Galaxy in Andromeda is located beyond our galaxy?
That became clear once the telescopes were powerful enough to distinguish individual stars in the galaxies. Before that, they were seen only as "nebulae" (cloud-like objects), and it wasn't clear whether M31 (for example) was part of our own galaxy. M31 is also known as the Andromeda Galaxy.

What discovery made Edwin hubble believe there there is more universe than the milky way?
Hubble did not discover that there were other galaxies; that had been discovered earlier. But Hubble was the first to demonstrate that the more distant another galaxy is, the faster it is moving away from us. Edit: I'm not sure that's right. Hubble was surely the first to prove that a "spiral nebula" was too far away to be in the Milky Way. That nebula is what we now call the "Andromeda galaxy". I know that Slipher and others did important earlier work on red shifts, but I'm pretty sure Hubble did discover that other galaxies existed.
Who showed that other galaxies existed?
The astronomer Edwin Hubble provided evidence in the 1920s that other galaxies existed beyond our own Milky Way. By observing Cepheid variable stars in the Andromeda Galaxy, he demonstrated that it was a separate galaxy located far outside our own. This discovery revolutionized our understanding of the universe's scale and confirmed the existence of other galaxies.
What is the farthest galaxy ever observed by Hubble?
The farthest galaxy ever observed by the Hubble Space Telescope is GN-z11, located about 13.4 billion light-years away. This means we are seeing the galaxy as it was just 400 million years after the Big Bang.
What was Edwin Hubble's equation?
Hubble's equation states that the velocity at which various galaxies are receding from the Earth is proportional to their distance from us.The law is often expressed by the equation v = H0D, with H0 the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v. The SI unit of H0 is s-1 but it is most frequently quoted in (km/s)/Mpc, thus giving the speed in km/s of a galaxy one Megaparsec away. The reciprocal of H0 is the Hubble time.
What did the hubble discover that indicated that the universe is expanding?
Edwin Hubble did not discover any planets. He is most famous for demonstrating that the "spiral nebulae" were, in fact, other galaxies lying far outside the Milky Way, and for discovering the relationship between redshift (= recessional velocity) of galaxies and their distances.
Is the Hubble galaxy the closest major galaxy to our own?
No, the Hubble Galaxy (Messier 31, or the Andromeda Galaxy) is not the closest major galaxy to our own. The Andromeda Galaxy is located about 2.537 million light-years from the Milky Way. The closest major galaxy to us is the Triangulum Galaxy (Messier 33), which is approximately 3 million light-years away.
How did Edwin Hubble measure the distance to the Andromeda Galaxy?
Edwin Hubble measured the distance to the Andromeda Galaxy using Cepheid variable stars as standard candles. By observing how the brightness of these stars changed over time, he could determine their true brightness and then calculate their distance based on their apparent brightness. This allowed him to estimate the vast distance to the Andromeda Galaxy.
Is the hubble galaxy the closest galaxy to your own?
Our galaxy is called the Milky way, but the closest neighbouring galaxy is called the Andromeda galaxy.
How did Edwin Hubble measure the distance to the andromedia Galaxy?
Edwin Hubble measured the distance to the Andromeda Galaxy by observing the light from its variable stars, specifically Cepheid variables. He utilized the relationship between the luminosity and the pulsation period of these stars to determine their absolute brightness. By comparing this intrinsic brightness with the observed brightness, Hubble could calculate the distance to Andromeda, ultimately establishing it as a separate galaxy outside the Milky Way. This groundbreaking work significantly expanded our understanding of the universe.
How did Edwin Hubble's discovery that the Andromeda galaxy was far away of our own galaxy contribute to astronomers' knowledge about the size of the universe?
Prior to Hubble's discovery scientists generally believed that our galaxy was the entire universe. Hubble found that the Andromeda galaxy was, then called the Andromeda Nebula, was not a part of our galaxy but a galaxy unto itself far beyond the edge of the Milky Way. This discovered demonstrated that the universe is much larger than scientists have believed.
What is the general relationships between a galaxy's distance from earth and its speed?
were part of a galaxy?!! _____________________________ Yes, we are. It's part of the Earthling's Handbook; didn't you get a copy? The majority of other galaxies are moving away from us. (One notable exception is the Andromeda Galaxy; our Milky Way will probably collide with Andromeda in about 4 billion years or so.) Curiously, the farther away from us a galaxy is, the faster it seems to be receding! The relationship is called "Hubble's Law" for the man who figured it out, Edwin Hubble. (The Hubble Space Telescope is named in his honor.)
Who measure the distance of Andromeda nebulae?
Hubble
If Hubble saw the Andromeda galaxy first and deduced the galaxies are all flying away from each other why is the Milky Way soon going to collide with Andromeda?
andromeda and milky way (us) maybe moving in the same direction but the milky way is the smaller and 'lighter' so we may be moving faster than the 'bulky' andromeda galaxy hence why there is a strongly suggested theory that we may collide but not in our lifetime. hope this helps
When was the Andromeda Galaxy discovered?
The Andromeda Galaxy is one of the few galaxies that is observable with the naked eye. Because of this, it cannot be said to be "discovered" as it has obviously been viewed by "man" since the earliest times.

What characteristics do Andromeda galaxy stars have?
Basically, the same characteristics that the stars in the Milky Way - our own galaxy - have. Aside from the fact that Andromeda is somewhat bigger, the two galaxies are thought by astronomers to be very much alike. When Edwin Hubble studied the Andromeda Galaxy in the early 20th century, he was able to discern within it several "Cephid variable" stars, which proved, among other things, that Andreomeda was a galaxy, like ours. Prior to that time, it was believed that the Milky Way was the only galaxy - the others were "clouds".
