Hubble devised subcategorization for spiral galaxies first based on whether the galaxy exhibited a bar and then how well the spiral arms were defined. The classes are designated as Sa, Sb, and SC with the Sa class being the most tightly wound. A capital B designation after the S indicates the presence of a bar as well.

Who devised the classification system for galaxies?
In 1962, astronomer Edwin Hubble decided to classify galaxies according to a logical scheme. he eventually decided to classify them according to their shape. Today, galaxies are divided into four main groups: spiral, barred spiral, elliptical, and irregular.
What is the name of the telescope that they use to see galaxies?
the hubble telescope edwin hubble :)
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.
The scientist who proved the existence of galaxies other than the Milky Way was who?
Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
What was the hubble space telescope named after?
The Hubble Space Telescope was named after the American astronomer Edwin Hubble, who played a crucial role in changing our understanding of the universe by demonstrating that galaxies are moving away from each other.
Who devised the classification system for galaxies?
In 1962, astronomer Edwin Hubble decided to classify galaxies according to a logical scheme. he eventually decided to classify them according to their shape. Today, galaxies are divided into four main groups: spiral, barred spiral, elliptical, and irregular.
What are the 4 main galaxy shapes?
There are various ways of categorising galaxies, often based on Edwin Hubble's work on the shapes galaxies. Classifications often give the four main types of galaxies as: Spiral (including barred spiral), Elliptical, Lenticular and Irregular.
What scientist discovered the three main types of galaxies?
spiral galaxies elliptical galaxies and irregular galaxies
What observation did Edwin hubble make about the movement of galaxies?
In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.
What is the name of the telescope that they use to see galaxies?

What important observation did Edwin Hubble make about the movement of galaxies?
In the late 1920s, the astronomer Edwin Hubble discovered that most of the galaxies he observed were moving away from Earth.
What did Edwin hubble notice about the direction of movement of galaxies in space?
Edwin Hubble noticed that galaxies are moving away from us in all directions. This observation led to the conclusion that the universe is expanding, which is now known as Hubble's Law.
Edwin Hubble found the galaxy in 1923 where did he found it?
In 1923, Edwin Hubble showed that the "spiral nebulae" that were presumed to be within our galaxy, the Milky Way, were actually other galaxies that lay far beyond our. The following year, he showed that the Milky Way was just one of many galaxies in the universe. Hubble's discovery, announced on January 1, 1925, fundamentally changed the view of the universe.
What significance does Edwin hubble have to the world of science?
Edwin Hubble was an astronomer.He proved that there are a lot of other galaxies out there.He proved that those galaxies are moving away from us and the universe is expanding.
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.

What measurement was Edwin Hubble famous for?
Edwin Hubble was famous for measuring the red shift of distant galaxies and interpreting that as evidence of the expansion of the Universe.
