Who was the scientist that discovered these distant galaxies?
The scientist who discovered distant galaxies is Edwin Hubble. In the 1920s, Hubble observed that galaxies were moving away from us, leading to the formulation of Hubble's Law, which describes the expansion of the universe. His work fundamentally changed our understanding of the cosmos and established galaxies as separate entities beyond the Milky Way.
When did Hubble discover that the universe was expanding?
Edwin Hubble discovered that the universe was expanding in 1929 when he observed that distant galaxies were moving away from us, as indicated by their redshift in their spectral lines. This discovery led to the formulation of Hubble's law, which describes the relationship between a galaxy's distance and its velocity of recession.
What was Edwin Hubble the first to discover in 1925?
In 1925, Edwin Hubble discovered that there are other galaxies beyond our Milky Way. He also observed that these galaxies were moving away from us, leading to the discovery of the expansion of the universe.
How did Edwin hubble prove other galaxies exist?
Edwin Hubble proved the existence of other galaxies by observing the redshift of light from distant celestial objects. In the 1920s, he analyzed the spectra of these objects and discovered that their light was redshifted, indicating they were moving away from us. By correlating the redshift with their distances, Hubble established the relationship known as Hubble's Law, demonstrating that the universe is expanding and that these distant, redshifted objects were indeed separate galaxies beyond the Milky Way. This groundbreaking work fundamentally changed our understanding of the universe's structure.
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.
What did hubble discover as a result of studying red shift of distant galaxies?
that the universe was in 1904 expanding. this was due to the lack of blue shift, therefor it can be deduced that the red shift in orrcuring within the galaxy.
What did hubble find when studying the light from different galaxies?
When studying the light from different galaxies, Edwin Hubble was able to find out that the universe does radiate at wavelengths that our eyes cannot see.

This discovery led to the formulation of Hubble's law, which describes the relationship between a galaxy's distance and its velocity of recession.
What kind of Doppler shift did Hubble observe in these distant galaxies?
Most galaxies exhibit a redshift, meaning that they move away from us.
What is important about the Hubble telescope's discovery that there is a red shift in the spectra of galaxies?
The Hubble telescope did not discover that there is a red shift in the spectra of Galaxies. The telescope is named after the American astronomer, Edwin Hubble, who discovered the phenomenon in the 1920s.
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.
When did science discover that all matter is in constant motion?
If the galaxies are meant, it is credited to Edwin Hubble and became known as "Hubble's Law".
Why is it difficult to measure the Hubble constant H?
Both the speed and the distance of distant galaxies must be measured accurately.
What did Hubble find out about the most distant galaxies?
Hubble Space Telescope observations revealed that the most distant galaxies are much younger and smaller than those found nearby, providing insights into the early universe. These galaxies often exhibit irregular shapes and higher rates of star formation, indicating they are in a formative stage of evolution. Hubble's findings also support the concept of galaxy formation and evolution over cosmic time, showing that galaxies have grown and evolved significantly since their inception. Additionally, the discovery of these distant galaxies has helped refine the understanding of the universe's expansion and the influence of dark energy.
What do th spectra of distant galaxies collected today say about hubbles original findings?
The spectra of distant galaxies collected today support Hubble's original findings by showing that galaxies are moving away from us, indicating an expanding universe. The redshift in the spectra is evidence of this cosmic expansion, consistent with Hubble's discovery of the relationship between distance and redshift.
Why did Hubble find out about the most distance galaxies?
Hubble discovered the most distant galaxies primarily through his observations of redshift, which revealed that galaxies are moving away from us. This shift in the light spectrum indicated that the universe is expanding, allowing astronomers to infer the distance of these galaxies. By analyzing the light from these distant objects, Hubble was able to identify galaxies that were billions of light-years away, pushing the boundaries of our understanding of the universe's size and age. His work laid the foundation for modern cosmology and our understanding of the universe's evolution.
