Edwin Hubble discovered that the majority of galaxies are moving away from Earth, leading to the formulation of Hubble's Law. He observed a correlation between a galaxy's distance from Earth and its recessional velocity, indicating that the farther a galaxy is, the faster it is moving away. This discovery provided strong evidence for the expansion of the universe and fundamentally changed our understanding of cosmology.
What else can I help you with?
What did Edwin hubble discover about the redshift?
Edwin Hubble discovered that galaxies are moving away from us, and the further a galaxy is from us, the faster it is moving away. This phenomenon is known as redshift, where the light emitted from these galaxies is shifted towards the red end of the spectrum due to their motion away from us.
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.
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 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.
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".

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 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 YEAR DID EDWIN HUBBLE DISCOVER THE Milky Way?
Edwin Hubble did not discover the Milky Way; rather, he is renowned for his contributions to our understanding of the universe's structure and the existence of galaxies beyond the Milky Way. In the 1920s, Hubble provided evidence that the Milky Way is just one of many galaxies in the universe, using observations of the Andromeda Nebula. His work fundamentally changed our understanding of the scale of the cosmos.
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?
the hubble telescope edwin hubble :)
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 two quantities did Edwin Hubble compare to discover the expansion of the Universe?
Edwin Hubble compared the distances to galaxies (based on their brightness) and their redshifts (due to the Doppler effect) to discover the expansion of the Universe. By finding a relationship between these two quantities (dubbed Hubble's Law), he provided evidence that the Universe is expanding.
What scientist discovered the three main types of galaxies?
spiral galaxies elliptical galaxies and irregular galaxies
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.
