Why is light an important tool used in astronomy?
Stars are the sources of light. If they did not emit light, there would be no stars and thus no astronomy.
Would we see stars if there was no sun?
no,because the light of the Sun reflects off stars which makes them visible to us.
Can visible light travel through space?
Light can travel through space. All the light that we get on the earth's surface; usually travels from the sun through space before it can reach here.
Why does a telescope work at night?
Telescopes do not normally work well at night, unless you happen to be looking at stars and other planets. This is because the stars do not depend on our Sun shining on them to be bright. Think of the stars as you would, say, a row of flashlights a block away. With the naked eye with no moon or streetlights, you may not be able to see much farther than 15 or 20 feet, yet those flashlights at the other end of the block are very easy to see. The stars are similar: they make their own light, and you can see them a looong way away.
Do you use a spectroscope to study stars in the sky?
It is one tool that you can use. It is more for examining light and its properties, than for simple observation of stars, which you would use a telescope or binoculars for. It can be used to specifically examine the light to try and find out more about the stars and what they consist of.
Why can you still see stars after they have died?
The nearest star (other than the Sun) is 4.7 light-years from Earth, meaning it takes 4.7 years for light from that star to reach us. That star could die and we would not know it for 4.7 years. Some stars are billions of light years away, it would be billions of years before we noticed that the star was no longer shining.

What colour will red boots look in red light?
They will look red. This is because red boots only reflect red light. If white light was shining on them then they would still appear red because the red light would be reflected into your eyes and the other colours from the spectrum would be absorbed. However, if, for example blue light was shining on them, they would look dark/black because there is no red light to reflect.
What would the stars look like when earth is 1 light year old?
"Light year" is a distance, not a time. It's the distance that light travels through space in one year, roughly 5,878,500,000,000 miles. The earth is about 4,500,000,000 years old now. The stars probably look pretty much the same now as they did when the earth was born, except that they're different stars now ... some of the old ones have disappeared and newer ones have started shining since then.
When you are sleeping and light shines through the window can a person see the light with their eyes closed?
When you are awake with your eyes closed, you can tell when there is a light on or a light shining nearby. However, if you are unconscious or sleeping, the brain may not detect a light shining. During the REM period of sleep, for example, you would be dreaming and not using your eyes to see your surroundings.
What color would appear if red green and blue light shining on a white sheet of paper?
grayish red
How many meters per second would it take stars light to reach earth?
Light travels at about 300,000 metres per second. The time taken for that light to reach us would depend on the stars distance.
What unit would you use to measure the distances from stars?
To measure the distance of stars you have to measure by light years.
What process cause stars to give off heat and light?
what causes stars to give off heat and light is when the poporazzi abushes them and they get really mad...that would be the heat. and the flashes form the cameras would be the light
What is the negation of the statement The Sun is shining?
The negation of the sentence the sun is shining would be that the sun is not shining.
What is the size and color of the stars?
The stars are just like the sun. If you fly to a star it is probably bigger than earth but sometimes it could be as big as a country. If the star is dead it would be like a rock if it is alive they would be shining in the sky as a similar color to the sun.
