TED-ED: Light seconds, light years, light centuries: How to measure extreme distances - Yuan-Sen Ting
When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine...
