Extra stellar systems are so far away from our own that we couldn’t even hope of developing a tape measure long enough to determine how far away they really are. On the other hand, astronomers can ...

Measuring the period of their pulsations is easy, as is measuring their brightness. Once we know how bright they really are, we can again solve for their distance.

We've taken three great steps forward in our quest to measure the distance to the stars, but we've still got further to go.

A team of astronomers has used asteroseismology, or the study of stellar oscillations, to accurately measure the distance of stars from the Earth. Their research examined thousands of stars and ...

How Do We Measure the Distance to Stars? The answer lies in the tiny shifts we see in a star’s position as Earth revolves around the sun. Scientific American contributor Christopher Crockett ...

Astronomers use the well-known period-luminosity relationship of Cepheid variable stars to calculate distance across the cosmos.

"We found that the acoustic oscillations of red giant stars tell us how to best measure cosmic distances using the Tip of the Red Giant Branch method," Anderson said in a statement.
