The parallax method of measurement forms the lowest rung of what is called “the cosmic distance ladder,” the first in a succession of methods by which astronomers determine the distances to ...

The distance of 66,000 light-years almost doubles the previous record of the longest distance directly measured. The direct measurement method used was trigonometric parallax, first used in 1838.

A way of estimating more accurate distances to the thousands of so-called 'planetary nebulae' dispersed across our Galaxy has just been announced by a team of three astronomers.

But now, by using a technique called the trigonometric parallax method, a team of astronomers led by Xu Ye have been able to get a better sense of our location relative to other stars.

In 1838, Friedrich Wilhelm Bessel won the race to measure the first distance to a star other than our Sun via the trigonometric parallax—setting the first scale of the universe. Astronomers from ...

A way of estimating more accurate distances to the thousands of so-called 'planetary nebulae' dispersed across our Galaxy has just been announced by a team of three astronomers based at the ...

Astronomical distances are most easily measured using the so-called trigonometric parallax, in which astronomers make use of the annual shift in the star's position as a consequence of the Earth's ...

Hubble precisely measures distance to ancient star cluster The new measurement uses straightforward trigonometry, the same method used by surveyors ...
