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 ...

Over the 25 years I’ve written this column, I’ve often marveled at the mind-boggling distances to many celestial objects. Astronomers don’t often use miles to express stellar and galactic distances ...

It isn't easy to measure the distance of stars. We can't travel to them, counting the miles as we go, nor can we simply say that brighter stars are closer and dimmer ones more distant. Instead, we ...

The two sets of images were compared, showing definite parallax. According to NASA, this is not only the first time a spacecraft has measured stellar parallax, it is also the longest measuring ...

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 ...

As NASA's New Horizons spacecraft traveled through the Kuiper Belt at a distance of 438 million miles from Earth, an international team of astronomers used the far-flung probe to conduct an ...

(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.
