Why scientist don't expect to find galaxies that have large blue shifts?
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.
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 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 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 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 kind of Doppler shift did Hubble observe in these distant galaxies?
Most galaxies exhibit a redshift, meaning that they move away from us.
According to Hubble's Law the most distant clusters of galaxies are?
The basic idea of Hubble's Law is that galaxies (or galaxy clusters) that are farther away move away from us faster than those that are closer to us.The most distant galaxy yet found is a protogalaxy with the designation UDFj-39546284, with a redshift z = 11.9, about 13.42 billion light-years distant from the Milky Way.In case you are asking for the most distant CLUSTER of galaxies, and not the most distant astronomical galaxy, the answer would be the cluster (or protocluster, science is not yet sure about the nature of this structure) which denomination is BoRG-58 , with a redshift z≅8, and about 12 billion light-years distant 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.
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.
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 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 is the most distant galaxy the Hubble can detect?
The furthest Hubble as ever gazed into the universe is the Hubble Ultra Deep Field. Search that in google and check it out.
Scientists believe that the more distant galaxies formed?
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
Which instrument has been used to detect the oldest most distant objects in the solar system?
The Hubble Space Telescope has been used to detect the oldest and most distant objects in the solar system. Its powerful cameras and instruments help astronomers study these objects, such as distant galaxies and stars, by capturing their light and providing valuable insight into their formation and evolution.
What is the most famous satellite in space?
The Hubble Space Telescope is one of the most famous satellites in space. It has provided stunning images of distant galaxies and has helped scientists in making groundbreaking discoveries about the universe.
How far away are the most distant galaxies?
That is impossible to answer because scientist don't know ALL the galaxies.
Why scientist don't expect to find galaxies that have large blue shift?
