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 is the galaxy classification?
The current galaxy classification is based on. * The Hubble sequence is a morphological classification scheme for galaxies invented by Edwin Hubble in 1936 * The de Vaucouleurs system for classifying galaxies is a widely used extension to the Hubble sequence, first described by Gérard de Vaucouleurs in 1959. * The Yerkes (or Morgan) scheme uses the spectra of stars in the galaxy
How did Edwin hubble sub-categorize spiral galaxies?
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.
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
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 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.
Who classified the galaxies?
Edwin Hubble Classified the Galaxy different categories depending upon its visual appearance.
Where did Edwin hubble study?
Edwin Powell Hubble (November 20, 1889 - September 28, 1953) was an American astronomer who studied the most distant objects visible at the time and contributed to our understanding that the galaxy is expanding.
What is Edwin Hubble's whole name?
Edwin Powell Hubble
Is Edwin Hubble an American?
Yes. Edwin Hubble was American.
What did hubble discover near the end of the 1920's?
In the '20s Edwin Hubble discovered that the Milky Way is just one of millions of galaxies and he showed that the galaxy is expanding.
