A wide open space (It could be your backyard or a park.) Two Hula-Hoops (Alternatively, you could use two flat rocks or bricks that you can sit on.) A yardstick or meterstick (Use one that has clear ...

Have you ever wondered how astronomers measure the distance to other objects in the universe? How do they make claims that this nebula is 1,500 light years distance or that galaxy is 2.5 million light ...

How is astronomical distance determined? Just cannot get my head around cepheid variables, parallax, etc. How is it possible to tell how far away something is when you cannot bounce a radar beam off ...

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 ...

No, but it was considered. The reason parallax measurements weren’t taken with Voyager or any other interplanetary spacecraft is simply that astronomers can do better from the ground or with dedicated ...

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 ...

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 ...

For the first time, astronomers have directly measured the distance to a spot clear across the galaxy. The established but challenging technique promises a new way to map the structure of the Milky ...
