Age is kind of a mystery to me.
Distance, though...
Spectra show characteristic lines. They indicate the presence of specific elements, and they're always at the same frequency.
Except they're not. Very distant objects show the right pattern of lines, but "shifted" to the red to some amount. Since we know what the lines' frequencies are supposed to be, we can calculate the amount of this "redshift".
The amount of redshift tells us, indirectly, the distance, by comparison to other objects that we can actually measure the distance to using other techniques (redshift is proportional to distance).
This sort of relates to "age" in a way: the further away something is, the longer it took for the light to get to us, and so based on the distance we can calculate that the light we're now seeing must have actually been emitted x million years ago or whatever (physicists are cringing at this sentence, because relativity says there's no such thing as universal time).

We are able to tell the different contents of our Universe based on the color of light that is being emitted through the Telescopes eye. The telescope only reads the certain light spectrum's one at a time. Once the Hubble sends the information back to earth, our computers mix those lights into a black and white photo. This in terms takes many many hours to complete. Those beautiful pictures of the Universe and Galaxies are down with the basic spectrum's of light.
Light has also gave us a better understanding of what our neighboring stars are created from. Its a reason why we know stars from 100's of light years away are made up of liquid Hydrogen. This helps us better understand how stars are boring, how they destruct and how they interfere with its neighboring planets

How did Copernicus' heliocentric discovery help the universe?
It did not help the universe at all but it did help us in the continuing efforts to understand the universe.
What is the spectrum of the moon?
The lunar spectrum is identical to the solar spectrum. The moon reflects the sun's light, and it cannot help but be the same.
What is the James Webb space telescope going to study?
It is going to replace the Hubble Space Telescope in the year 2018. It will study the edges of the universe, where the light from the creation of the Universe is still in transit to the Earth. So what JWST will do is to look at the past, billions of years ago, when the Universe was only a few hundred million years old. This would help us understand more about the evolution of the Universe.
What spectum is obtained When any element in the gas phase is excited to the point where it emits visible light?
When any element is excited to the point where it emits visible light, it emits a unique spectrum. The mercury in a florescent lamp emits a spectrum in the ultraviolet spectrum. It excites phosphorus powder on the inside of the bulb. The ultraviolet rays strike the phosphorus and it emits white light. Sodium emits yellow light. Potassium emits purple light. Sodium actually emits two different yellows. Each element emits several different colors.The above is not wrong, but it doesn't really answer the question. I believe the answer the poster was looking for is emission spectrum.You may be correct. I have no intention of giving the emission spectrum of every element. I only wished to help the questioner understand what happens when an emission spectrum is produced. I had the idea that the questioner had the idea that every element produced the same emission spectrum. We interpreted the question differently.
How will Stephen hawking's theory about black holes help the world?
This will help the world by helping us more understand about black holes for when we are able to travel farther into the universe.
How does light help us understand the entire story of the universe?
light helps us understand the story of the universe due to somthing called red shift this is where the light waves are contorted to the red end of the spectrum this occurs in objects that are moving away from us. all galaxies in the universe are moving away from us we know this because of red shift.

This science help us understand the earth's place in universe?
Astronomy.
Why are astronomers important?
They help us understand the universe around us.
What is the spectrum of sunlight?
spectrum of light is the colors of son or u can say the elements of sun. we find out the elments of sun with the help of spectroscope, a prism in spectroscope help to break down the colors or spectra of sun light. spectrum of light is the colors of son or u can say the elements of sun. we find out the elments of sun with the help of spectroscope, a prism in spectroscope help to break down the colors or spectra of sun light.
What is the spectrum of the moon?
The lunar spectrum is identical to the solar spectrum. The moon reflects the sun's light, and it cannot help but be the same.
What enters the eye to help you see?
Electromagnetic radiation (light) limited to the narrow visible spectrum.

How does atoms help us understand God?
Because God(Father,Son, and Holy Spirit) is the true Graviton of the universe.
Each element will give off the same spectrum of light?
NO!!!! Each element gives off a unique spectrum of light.

What effect does a convex lens have on light?
It refracts light twice, such that the overall effect is that the light is converged. A ray diagram will help understand this.
