What was Edwin Hubble's equation?
Edwin Hubble is known for his work on the expansion of the universe, which led to Hubble's law. The equation for Hubble's law is v = H0 * d, where v is the velocity of recession of a distant galaxy, H0 is Hubble's constant, and d is the distance to the galaxy.
What did Edwin Hubble due to help prove the Big Bang Theory?
Edwin Hubble played a crucial role in providing evidence for the Big Bang Theory by observing the redshift of galaxies. He discovered that galaxies were moving away from each other, and the farther away they were, the faster they were moving. Hubble's observations supported the idea that the universe is expanding, which is a key component of the Big Bang Theory.
How did Edwin Hubble determine that the Great Galaxy in Andromeda is located beyond our galaxy?
That became clear once the telescopes were powerful enough to distinguish individual stars in the galaxies. Before that, they were seen only as "nebulae" (cloud-like objects), and it wasn't clear whether M31 (for example) was part of our own galaxy. M31 is also known as the Andromeda Galaxy.
How did Edwin hubble sub-categorize spiral galaxies?
Edwin Hubble sub-categorized spiral galaxies into "normal" and "barred" spiral galaxies based on the presence of a central bar structure. Barred spiral galaxies have a straight bar of stars running through their center, while normal spiral galaxies do not have this feature.
What is the name nasa's most famous telescope?
The first large space telescope was the Hubble, and it's probably still the most famous one. But a LOT of the new and exciting work being done is using the Kepler Space Telescope, a device which was specially designed to search for planets around neighboring stars.
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 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 kind of Doppler shift did Hubble observe in these distant galaxies?
Most galaxies exhibit a redshift, meaning that they move away from us.
Who first propsed that the universe is expanding?
The astronomer Edwin Hubble was the first to find evidence of the expansion of the Universe, through his observations of distant galaxies. He observed that light emitted from most of the distant galaxies was more red in color. This is known as the Doppler effect or Doppler shift, where objects that emit a certain wavelength and move away from the observer appear to have a longer wavelength than the true wavelengths to the observer. It's the opposite case when objects emitting waves that are coming closer to the observer. These observations lead Hubble to believe that these surrounding red-shifted galaxies are moving away from us. Since most of the galaxies were moving away from us, and since Hubble found that with increasing distance between the galaxies there is an increasing speed at which they are moving apart, he concluded that the Universe was and still is expanding.

How do the speeds at which most nearby galaxies are moving away from the earth compare to the speeds of distant galaxies that are moving away from earth?
Distant galaxies are moving away from Earth at faster speeds compared to nearby galaxies. This is due to the expansion of the universe, where galaxies farther away experience a greater redshift, indicating faster recession velocities. This relationship is described by Hubble's Law, which states that the recessional velocity of a galaxy is directly proportional to its distance from us.
What did astronomers Edwin Hubble discover that led to the formulation of his law?
Basically, his discovery was that most galaxies move away from us; and that the galaxies that are farther away, also tend to move away faster.
What imporatant observation did Edwin Hubble make about the movement of galaxys'?
That most galaxies move away from us; and that the general tendency is that galaxies that are farther away move away from us faster.

Is the hubble telescope still in operations today in 2007?
Yes, and better than ever. Google "Hubble Ultra Deep Field" for some of the most amazing pictures you will ever see. Thousands upon thousands of galaxies.
