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 ...

The cosmic distance ladder employs a series of methods to measure increasingly vast astronomical distances, with each technique building upon the previous one for verification. Parallax, using stellar ...

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 ...

The cosmic distance ladder could soon have another rung. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. In around 5 billion years, the sun will ...

Let’s try a demonstration that we all enjoyed in elementary school. Close one eye, hold out your thumb at arm’s length, and align it with an object on the other side of the room. Without moving your ...

Yardsticks are very useful around the house when you need a measurement. (I have also used them to fish out toys the cat knocked under a low piece of furniture.) They are standards by which we can ...

(Nanowerk News) For most of us, the countless bright spots in the nighttime sky all seem to be stars. But in fact, some of those spots are actually planets, or distant suns, or even entire galaxies ...

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 ...
