A light year is the distance that light travels in a year, so it is a measure of distance, not time. Light travels at about 186,000 miles per second or about 300,000 kilometres per second. There are 31,536,000 seconds in a year. There is about 5,869,713,600,000 miles in a light year or about 9,445,950,434,500 kilometres.
CCDs, or Charge-Coupled Devices, are the light sensor chips used in all digital cameras. The application to astronomy, especially to space telescopes and space probes, is obvious.
Astronomy is all about the things in outer space and planets are in outer space.
Astronomy is the study of the outer space. If you look up at the sky at night you are looking at outer space which is astronomy.
Astronomy is the study of space.
Astronomy IS the study of the Universe, i.e., basically, of outer space.
Astronomy is about space, and the only way people will know about space is by exploring it. space programs help people learn about it.
Synonyms of astronomy are: stargazing, starwatching, radio astronomy, astrophysics, and space science.
Astronomy is the scientific study of natural objects and phenomena in outer space.
Because of the vast distances in space and a light year is the distance of light travelling at 186,000 miiles per second in one year.
Common units used in astronomy include astronomical unit; light-year; parsec.
Because if we know the knowledge of astronomy, we will be smarter.
Astronomy is the study of celestial objects (Space objects).
Astronomy is the study of outer space and the universe. This includes the solar system and earth in space.
Yes it's the study of space.
Astronomy has several sub-branches as general astronomy, astrophysics and space sciences.
A light year is a much larger unit and so is better suited to the huge distances in space. Therefore, it is a more useful measurement in astronomy than a meter.
A PC is a parsec, a length of measurement in space roughly equal to 3.26 light years or 19,560,000,000,000 miles.
A black hole is an object in space. Astronomy is the study of objects in space. Therefore, black holes would be among the topics covered by astronomy.
Astronomy is the study of Earth and other things out in the endless space.
Not just stars. Astronomy is the study of everything in space.

It's an object in outer space; that's basically what astronomy is about - studying objects in outer space.
