(Nanowerk News) 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.

The average distance between the Earth and Sun measured using trigonometry is 93 million miles, not 3,000 miles as claimed in a viral post online. The author of the post claims that measuring with a ...

Parallax is the observed displacement of an object caused by the change of the observer's point of view. In astronomy, it is an irreplaceable tool for calculating distances of far away stars. When you ...

Astronomers have succeeded in precisely determining the astronomical yardstick for the Galaxy based upon precise distance measurements from advanced radio telescopes. The new findings are that the ...

Astronomers directly measured the distance to a region on the far side of our Milky Way Galaxy, past the Galaxy's center. Bill Saxton, NRAO/AUI/NSF; Robert Hurt, NASA Using a 180-year-old technique ...

Try this experiment: extend your thumb at arm’s length and close one eye at a time. Your thumb will seem to ‘jump’ between two positions as you switch the eye that is closed. That jump is known as ...

Astronomers from the U.S. Naval Observatory (USNO), in collaboration with others from the REsearch Consortium On Nearby Stars (RECONS), have determined new distances to a group of faint young stars ...
