B C and D, but there's a fair chance I've given you deliberately false information because you're clearly cheating on your homework. In future phrase the question in a less obvious way.

It doesn't. Infact, what is the shape of the galaxy? Where would you draw the perimetres?

Cepheid variable stars have been used to determine the?

1)placing cosmological constraints on the expansion of the Universe through the determination of distances to galaxies 2)to measure many characteristics of our galaxy and our relationship to it


What is the process used by astronomer to estimate the number of galaxies in the universe?

They used a method called "representative sampling" to obtain their estimate. The sky is divided into sections of equal size and the number of galaxies in one section are counted. The count from that one section is then multiplied by the total number of sections in the sky


How is light years used in science measurement?

A light year is the distance light travels in a year. That is roughly 6,000,000,000,000 miles (six trillion miles). Thus such a unit is used only to measure the largest distances, those between stars and galaxies.


What is a spectrascope?

The correct spelling is spectroscope. A spectroscope is a scientific instrument that is used to measure properties of light waves. It is an optical device for producing and recording spectra to be examined.


Why was the term light year in invented?

Distances to other planets, other stars and other galaxies are very large, making measurements in meters or kilometers difficult to handle (although scientific notation can be used). As a result, astronomers have gotten accustomed to measure distance within the Solar System in astronomical units, and to other stars and galaxies, either in light-years or in parsecs.
