Who is the person who discovered galaxies outside the milky way?

Edwin Hubble was the first to suggest that the Milky Way was just one among a number of galaxies or, as he called them, "pocket universes". Other individual galaxies had been observed previously, but they had been believed to be stars within the Milky Way.

∙ 11y agoIn 1923, Hubble found dozens of these variable stars in Andromeda, and determined their distance. He calculated that Andromeda must be at least 10 times farther away than the farthest stars in the Milky Way. The Andromeda nebula was really the Andromeda galaxy. This discovery implied that the other, even fainter, spirals were probably also galaxies even farther away.

Galaxies had been discovered much earlier but were not intially described as or categorised as spiral galaxies.

Not only did he discover that galaxies exist, he discovered that galaxies move away from each other with a constant acceleration.
This led to the Big Bang theory, that some time in the earliest past everything started off in a single point.
And as it, then, exploded, everything flies away with a constant acceleration.

∙ 10y agoThe discovery of external galaxies had to wait for a yardstick to be produced that could measure the large distances. Cepheid variables were discovered in the Andromeda nebula M31 by Edwin Hubble in 1924 that showed its distance and demonstrated it lies outside the Milky Way.
Cepheid variables are a class of variable stars that have a brightness that cycles very regularly, and the period of the cycle depends on the size and absolute brightness of the star. Delta Cephei is the best-known Cepheid variable star.
The relationship between the brightness and the period was discovered by Henrietta Leavitt after a study of Cepheid variables in the Magellanic clouds. All those stars are at approximately the same distance so she was able to calculate the period/luminosity relationship that they follow.
If a Cepheid variable is discovered and its period measured, its absolute magnitude can be calculated and compared with its visual magnitude to find the distance.

What are the other galaxies accept Milky Way?
The observable Universe has at least a hundred billion galaxies. The galaxies closest to us are part of the so-called "Local Group" (that is, the group that includes our galaxy); this Local Group includes our own galaxy (i.e., the Milky Way), the Andromeda Galaxy, the Triangulum Galaxy, and about 50 dwarf galaxies such as the Large Magellanic Cloud and the Small Magellanic Cloud. Then, of course, there are hundreds or thousands of galaxies "near-by" as distances between galaxies go, but outside of our Local Group.
The Milky Way Galaxy and about 17 other galaxies within 3 million light-years of the Milky Way Galaxy are collectively known as what?
The Milky Way and 16 other galaxies compose the local group.
Who is the father of the Milky Way?
Except in a metaphysical sense, galaxies do not have parents.
Which galaxy does our solar system belong to?
Not "galaxies", just one galaxy. Our galaxy is called the Milky Way.
What other types of galaxies are there besides the milky way?
The answer is YES. There are an estimated 200 billion galaxies in the known Universe. Most of these galaxies are relatively similar to our own, some bigger, some smaller, some differently shaped. Most galaxies hold 50-200 billion stars, and average about 50,000 - 100,000 light years across. Light travels at 180,000 miles PER SECOND, so if it only takes 2 seconds to get to the moon, 30 seconds to Mars, but 100,000 light years to cross our own galaxy, imagine the size! Mind boggling!
Who discovered the existence of galaxies outside the milky way?
The person who discovered the existence of galaxies outside of the milky way was Edwin Hubble. He also discovered that galaxies move away from each other with a constant acceleration, leading to the big bang theory.

Who discovered that there were other galaxies besides the milky way?
Edwin Hubble
When did Edwin Hubble announce the discovery of galaxies outside Milky Way?
1924
What are some galaxies discovered other than the Milky Way?
andromeda(m31) Lmc Smc.
Are there galaxies in the milky way?
The Milky Way is our galaxy, the are no other galaxies within it though we are part of a local group of galaxies.
What are examples of the milky way and Andromeda galaxies?
Spiral galaxies
Is the milky way a universe?
No. The Milky Way galaxy is just one of billions of galaxies in the Universe. Just like there are billions of planets in the Milky Way Galaxy, there are also comparable numbers of planets in other galaxies.
Is the milkyway your only galaxy?
The Milky Way is not the only galaxy. There are more than a trillion times a trillion galaxies in the whole universe. Scientists have already discovered many tens of thousand galaxies.
Could you exist if galaxies did not?
no we couldn't because galaxies mean the milky way and if the milky way wasn't here we wouldn't
Are there galaxies other than the Milky Way?
There are billions of galaxies in the Universe.
Your galaxy is a part of a group What is the name of the group and the two galaxies in it?
The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".The local group of galaxies that include our Milky Way is called the "Local Group".
