It is the equivalent of how far light can travel at the speed of light in one year.

A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
"light-year"
"Light year" is a distance. It's defined as the distance light travels in one year,through vacuum.That's a huge distance compared to the daily experience of human beings ... about5,874,600,000,000,000 miles, or more than 31 thousand round trips to the sun and back.It's used in discussion of the distances between objects in space, and it actuallyturns out to be not a so large a unit at all. The nearest star outside of our solarsystem is about 4.2 light years distant from us, and the nearest galaxy outside ofour Milky Way is about 2.5 million light years distant from us.
Probably, the word was light year, and this distance is that travelled by light in one year. Of convenient use in distant astronomy.From the most distant stars, we are just now seeing the light that has been travelling for 4 billion years or so.
one light year is a measurement of time but one light year in distant is many millions of miles so not they cant
Light a Distant Fire was created in 1988.
Light a Distant Fire has 432 pages.
It depends on where you are measuring it from. Its distance from the earth varies depending of the relative positions in their orbit, but all planets in our solar system are considerably less than 1 light year distant.
"Light-year" and "parsec" are two units of length used in astronomy - for distant objects. 1 parsec = 3.26 light-years. A light-year is defined as the distance that light travels in a year. A parsec is defined as the distance at which an object would have to be to have a parallax of one arc-second.

Distant Light - The Hollies album - was created on 1971-10-08.

The fantastic Novel, Distant Waves, was published in the year of 2009.
The light from distant galaxies is redshifted. The only reasonable explanation for that is that the galaxies are moving away from us.
Distant stars give off less light
