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 is the relationship between red-shift and distant galaxies?
Redshift is the phenomenon where light from distant galaxies appears to be shifted towards longer (redder) wavelengths. This is due to the expansion of the universe causing the galaxies to move away from us. The amount of redshift is directly related to the distance of the galaxy from us, with more distant galaxies experiencing higher redshift.
Can you see your own galaxy in the night sky?
No you would see an entirely different vista. Most of the stars you can see from earth would not be visible to the naked eye from the galactic core, and they would also be lost in a blaze of glory of the core suns. From within a planetary atmosphere you probably would not be able to see stars even at night, due to the ambient light. The core suns are packed about a quarter of a light year apart.
When astronomers study distant galaxies they notice changes to the waves they observe describe the change to the waves they observe?
Because the universe as a whole is expanding, distant galaxies are moving away from us. As a result, electromagnetic waves emitted by those galaxies experience what is known as a red shift. Their wavelengths get longer.
Why is spring one of the best seasons to observe distant galaxies?
Spring is a good season for observing distant galaxies because it offers clearer skies with less atmospheric turbulence compared to other seasons. This results in better visibility of faint objects, allowing astronomers to capture more detailed images of distant galaxies. Additionally, spring nights are longer and have darker skies, providing more observing time for studying these celestial objects.
The visible part of distant galaxies is the galaxies what?
The "nucleus".
When the ultraviolet light from hot stars in very distant galaxies finally reaches us what form does it reach the Earth in?
visible light

Are quasars part of your solar system?
No, quasars are not part of the solar system. Quasars are extremely distant and energetic objects located in the far reaches of the universe, millions or billions of light years away from our solar system. They are powered by supermassive black holes at the centers of galaxies.
Why do scientist study the light coming from distant galaxies?
They study distant galaxies because they want to know whats out in other galaxies and how many planets it has
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.
The fact that the light from distant galaxies is red-shifted suggests that the galaxies are?
Moving away from us
How do the distant galaxies ussually move?
Away from us.
Where is the distant galaxy?
There are distant galaxies all around us - in all directions, and at varying distances.
What is true in Number the Stars by Lois Lowry?
The number of stars, as in distant "suns", are large. In our solar system, there is one star. In our galaxy, there are many, many stars. In all the visible galaxies, the number is yet larger. And what about all the presumed galaxies beyond our vision?
What is the method used view distant galaxies?
Gravitational lensing
What destroyed the steady state theory?
Briefly, the Steady State theory assumes that the Universe looked the same in the past as it does now. Observations of distant galaxies showed that this is not the case - distant galaxies are quite different to the ones that are closer by. Note that if you look at distant galaxies, you are observing the past of the Universe, because of the time it takes light to get here. That evidence played a part, but it was the detection of the "cosmic microwave background radiation". That was what convinced most astronomers that the Big Bang Theory was correct.
