How was the evidence for hubble law collected?
The evidence for Hubble's Law, which shows the relationship between distance and recession velocity of galaxies, was collected through observing the redshift of light from galaxies. Astronomers used spectroscopy to measure the redshift of galaxies, which is caused by the Doppler effect as the galaxies move away from us. By studying the redshift of galaxies at different distances, astronomers were able to support the idea that the universe is expanding.
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.
Why is the Hubble telescope valuable for studying objects outside of your solar system?
The Hubble is important to study objects in distant space, since it has a powerful lens's, which allows other galaxies light into it. This gives us pictures of places so far away, that it is impossible that a human will ever go there. The Hubble allows us visions of our universe, that we otherwise, would not have.
What are two important discoveries hubble made that proved other galaxies exist outside our own?
Hubble discovered that the nebulas were galaxies based on the powerful telescope at Mt Wilson. The second discoveries was the red shift relationship v=HD shows that the galaxies were outside our own galaxies definitely and quantitatively, using light sources in galaxies that were standard sources that could calibrate the distance.

Will Hubble make a 3D map of at least 100 billion galaxies in the observable universe?
No, because it will be impossible for Hubble make a 3D map of at least 100 billion galaxies (i.e. 60 billion spiral and barred spiral galaxies, 20 billion lenticular galaxies, 15 billion elliptical galaxies, and 5 billion irregular/peculiar galaxies) in the observable universe, at distances up to 13 billion light-years; since the observable universe is 13.7 billion light-years in diameter.

How far is the hubble deep field galaxies from the earth?
The Hubble Ultra Deep Field is a million second exposure into an area of the universe revealing numerous galaxies as far away as 13.7 billion light-years. By our reckoning, it is within a few hundred million years of the origins of the universe. But since the light took that long to get here, we have very little idea where the galaxies actually are right now in time.
How many galaxies are in the Hubble Ultra Deep Field?
There are at least 3000 galaxies in the Hubble Deep Field North (with billions of stars, planets, and moons in each one; as well as asteroids and nebulae). Their light has taken 13 billion years to reach Earth.
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.
The Doppler effect applies to light waves as well as sound waves. Astronomers use this to measure the motion of stars and galaxies. In 1929 Edwin Hubble discovered that light from distant galaxies was?
shifted to longer wavelengths, indicating that the galaxies were moving away from us. This observation led to the development of the theory of the expanding universe.
What are 2 discoveries that Edwin Hubble made which changed astronomy?
Edwin Hubble demonstrated that The Milky Way (our galaxy) is not the only galaxy that exists, but that there are many more galaxies in the universe. Also, he examined the wavelength of light coming from various galaxies, and determined that the further away it was, the greater the shift of wavelength into the red end of the spectrum. This is called 'Hubble's Law' and meant that the whole universe was expanding and not just that objects were moving within it.
