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.
Do astronomers see distant stars as they were long ago?
Yes. Because they are so far away, the light from the stars takes a long time to reach us (other than our star, the sun, which takes 8 minutes for the light to get here.) That way, a star 8 lightyears away, will be seen as it was 8 years ago.
During which Earth year did the light that you see from Canopus actually leave the star?
The year is 1681
What does narrator mean when she says that the sunlight you see actually left the sun 8.5 minutes ago?
light travels at 300 million meters a secons so it takes the light from the sun 8.5 minutes to reach the earth as it is a long way away :D
When we look in the night sky are we seeing the universe as it is?
No. We are seeing as it was. The light we are seeing now was first emitted some time ago. We see the other planets in our solar system as they were a few minutes to a few hours ago. We see stars as they were a few years to a few centuries ago. We see other galaxies as they were millions to billions of years ago.
What year did the alpha centauri light leave the star?
If you mean the light we see NOW, it left the star about 4.4 years ago, since that is the distance of the star, expressed in light-years.
Do you see stars as they are or as they were?
as they were, the time it took the light to travel from them to us determines how long ago we are viewing, even the light from our sun is 8 minutes old if I remember right.
When was Long As I Can See the Light created?

How long can you drive your 1997 Chevy lumina with the oil light on before changing oil?

How long to leave light on for Goldfish?
Goldfish do not need their tank light on for more than 6 hours. Unless you have a lot of live plants in your tank, leaving the light on for a long time will result in an increase in algae in your tank. If you begin to see an algae bloom, then you're best to leave the light off for several days.
How many light years can you see into our galaxy?
100 years ago

How were cars long long time ago?
Different, but you didnt say how long ago and that's relative. For some of the earliest-see below.
How can we know how some parts of the universe looked a million years ago?
Light takes time to travel, so light reaching us from a million light years away has taken that long to travel to us. We see what it looked like when the light left.
When looking at stars do you see the star or its light?
You see the light it gave off in the past, not now. The star you see now could have died years ago, but its light is still trying to reach earth.
