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.
As many as the stars.
You can see the Sun - and that is a star. The light from the sun swamps out the light from the stars, (signal to noise ratio).
Sometimes the brightness of the light from the moon drowns out the star's light.
You see a star as what it used to look like because the light from the stars takes so long to get to Earth. While the light it making its way to Earth the stars are burning out, some of the stars we can see may have been burnt out for millions of years now!
Yea. You can see the light reflecting off a planet and they look like stars. You can tell the diff. by if the 'star' you are looking at twinkles then it is probably a planet.
No. Every star you see produces its own light, just as the sun does. Which isn't surprising when you recall that the sun is a star.
The stars you see at night still exist.
Yes, when we observe stars, we are looking at the past because the light from stars takes time to travel to Earth, so we see them as they were in the past.
When looking up at the sky, you see dots instead of stars because stars are extremely far away and appear as tiny points of light due to the vast distances involved. The Earth's atmosphere and light pollution also scatter and block much of the light emitted by stars, making them appear as dots or points of light.
we only see stars in the sky at night because in the day it is light because of the sun. The stars are very light but the stars can not be seen because of the sunlight. So when it is pitch black you can see the stars so the stars sparkle in the sky without no light showing so its just the stars and the moon lighting up the world!
The stars that you see at night are part of our Milky Way galaxy, which contains billions of stars. Each star you see is a sun-like star that emits its own light, and they are at various distances from Earth.
Stars are pretty much the light from stars that died. The light is a supernova and the stars are so far away that it takes a long time for the light to reach us. Once the light reaches us, we won't see that star anymore. If you went up to the "star" there wouldn't be anything there. The light is still traveling toward us, but the star is gone.
