A free public lecture 7 p.m. Thursday at the Sam Noble Oklahoma Museum of Natural History, Timberdell Road and Chautauqua Avenue, will provide information about how scientists calculate astronomical ...
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 ...
Centuries ago the stars were believed to reside just beyond the planets of our solar system.It never fails to astound me how big the Universe is—how far away even the nearest stars are, let alone ...
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 ...
One of the greatest problems that confronts astronomers at the present time is an accurate knowledge of the distances of stars. From the earliest times, the relative positions of stars or their ...
The cluster of stars known as the Pleiades is one of the most recognizable objects in the night sky, and for millennia has been celebrated in literature and legend. Now, a group of astronomers has ...
Brown dwarfs are sometimes called failed stars. They’re stars’ dim, low-mass siblings and they fade in brightness over time. They’re fascinating to astronomers for a variety of reasons, but much about ...
For the first time, astronomers have produced a complete description of a black hole, a concentration of mass so dense that not even light can escape its powerful gravitational pull. Their precise ...
A research team from Imperial College London and the University of Barcelona has used data from astronomical surveys to measure a standard distance that is central to our understanding of the ...

How astronomers measure distance without travelling anywhere
It’s a bit mind-bending to realise that everything we know about the scale of the universe comes from people stuck […] ...
