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.

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.
When astronomers investigate the most distant galaxies they see evidence that?
When astronomers investigate the most distant galaxies, they find evidence that the universe was much younger and more active in its early stages. Observations of these galaxies reveal higher rates of star formation and interactions, suggesting that they were in a more chaotic and dynamic state. Additionally, the light from these galaxies has taken billions of years to reach us, allowing astronomers to study the evolution of galaxies over cosmic time. This research helps to deepen our understanding of the universe's formation and the processes that shaped its structure.
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 is Hubbles most recent discovery?
As of my last update in October 2023, one of Hubble Space Telescope's most recent discoveries includes the observation of a distant galaxy that appears to have formed only a few hundred million years after the Big Bang, providing insights into the early universe's formation and evolution. Additionally, Hubble has contributed to the ongoing study of exoplanet atmospheres, helping to identify potential signs of habitability in distant worlds. These findings continue to enhance our understanding of cosmic history and the nature of galaxies.
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 are the contributions of Edwin Hubble?
Edwin Hubble made significant contributions to astronomy, most notably through his discovery of the expansion of the universe, which led to Hubble's Law. He demonstrated that distant galaxies are moving away from us, with their speed proportional to their distance, providing strong evidence for the Big Bang theory. Hubble also played a crucial role in classifying galaxies and establishing the field of extragalactic astronomy. His work fundamentally changed our understanding of the universe and its structure.
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.
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.
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.
What evidence did Hubble base his thinking on?
Edwin Hubble based his thinking on several key pieces of evidence, notably his observations of distant galaxies and their redshifts. He discovered that most galaxies are moving away from us, with their light shifted to longer wavelengths, indicating an expanding universe. This led him to formulate Hubble's Law, which correlates the distance of a galaxy with its recessional velocity. His findings challenged the prevailing view of a static universe and provided crucial support for the Big Bang theory.
