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.

∙ 14y agoHubble realized that dimmer galaxies were probably farther away tha brighter galaxies. Thus, he tried to determine if there is a relation between the distances to galaxies and their red shifts. Using estimated distances based on relative brightness and the observed Doppler red shifts, Hubble discovered that galaxies that exhibit the greatest red shifts are the most distant.

∙ 10y agoHe discovered Cepheid variable stars in the Great Nebula in the Andromeda constellation. These stars are used as a way of measuring distances to other galaxies.
The first Cepheid he found he originally thought was a "nova".
Then he realised it was a variable. That enabled him to estimate the distance to
the Andromeda galaxy.

∙ 13y agoPrior to Hubble, most astronomers believed that our Milky Way galaxy was, in effect, the entire universe, and the wispy disc-like structures that could be seen at a distance were nebular clouds. By studying a certain type of variable star in some of these "clouds", Hubble deduced that they were separate galaxies from our own, and that there were many of them.

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.
What is the farthest galaxy ever observed by Hubble?
the farthest the hubble telescope can see is about 150 million light years away!
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.
What did the spiral galaxy remind Hubble of?
A spiral with a solid bar across the center. hope this helps it helped me.
How do red shifts were used by cosmologists to determine that the universe is expanding?
A Galaxy's red-shift can be used to determine how fast it is travelling away from you. The opposite is "blue-shift" which is what happens when the Galaxy is travelling towards you.The first astronomers, such as Edwin Hubble, to analyse the light coming from distant galaxies discovered that almost all of them were red-shifted, indicating that they were almost all heading away from us. This was the first indication that the universe was expanding.
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'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.
How did Edwin Hubble measure the distance to the Andromeda Galaxy?
He applied the period-luminosity relation to Cepheid variables.
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.)
Is the Hubble galaxy the closest major galaxy to our own?
There is no galaxy called the Hubble Galaxy
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
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".

According to Hubble's law the farther away a galaxy is?
According to Hubble's Law, the farther away a galaxy is the, faster it is moving away
What was the name of the first galaxy ever made?
a telescopeIn 1925, Edwin Hubble discover cepheid variable(s) in what we now call the Andromeda Galaxy. From those he could tell that the group of stars was too far away to be part of the Milky Way. It was the first proof that other galaxies exist.
