Why do scientists study distant galaxies to learn about galaxies?
Scientists study distant galaxies to understand the formation, evolution, and properties of galaxies over time. By observing galaxies that are far away, they can explore the universe at different epochs and gain insights into how galaxies have changed and evolved since the early universe. Studying distant galaxies also helps scientists refine theories about the laws of physics and the nature of the universe as a whole.
Scientist believe that the more distant galaxies are formed when?
Far or near, all galaxies were thought to be formed in the first half billion years of the formation of the universe ... that is, about 13 billion years ago. Note that we're seeing the distant ones in a younger stage of development.
When scientists look at very distant galaxies through powerful telescopes they see the galaxies as they were millions or billions of year ago. Why is this?
The vast distances involved means that the light we see left those galaxies a long time ago.
How long ago did the galazies form?
Galaxies began forming around 13.6 billion years ago, not long after the Big Bang that created the universe. Over time, gravity caused matter to clump together, eventually forming the galaxies we observe today.
How did scientists belived that distant galaxies were rapidly moving away from the earth?
Scientists believed that distant galaxies were rapidly moving away from Earth primarily due to the observation of redshift in their light spectra. This phenomenon, known as the Doppler effect, indicated that as galaxies move away, their light shifts toward longer wavelengths (red). Edwin Hubble's observations in the 1920s showed a correlation between the distance of galaxies and their redshift, leading to the formulation of Hubble's Law, which demonstrated that the universe is expanding. These findings provided strong evidence for the Big Bang theory and transformed our understanding of the cosmos.
Why do scientists believe that there are billions of stars in galaxies?
Because they can see them.
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.
Billions of years ago galaxies existed in?
Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.
What happens if a black hole is sucked into a black hole?
Its called a Super Black-hole and scientists believe it is what holds all galaxies together.
Where do scientists believe the first gases that created the atmosphere came from?
Scientists believe that the first gases that created the atmosphere came from volcanic activity and the release of gases from the Earth's interior.

Why do they think there are hundreds of thousands of galaxies?
They (scientists) think there are hundreds of thousands of galaxies because the universe is limitless so there may be billions of galaxies!
How do scientists believe heavier elements such as carbon and oxygen were created?

When was Sorrow Galaxies created?
Sorrow Galaxies was created in 2007-09.
Where would you find visible energy and invisible matter in universe?
A good example of visible energy is found in the stars. An example of invisible matter is the "dark matter" that scientists believe surrounds galaxies. So, one answer to the question would be "in and around galaxies".
When was Principal Galaxies Catalogue created?
Principal Galaxies Catalogue was created in 1989.
When was Stardust Galaxies created?
Stardust Galaxies was created on 2009-10-30.
