How do astronomers measure extreme distances?
Spotting objects that are very distant, and finding their distances is fascinating! When we look at the night sky, we get to observe a flat, two-dimensional view. So how do astrophysicists find the huge distances of stars and galaxies from Earth? Yuan-Sen Ting from TED-Ed demonstrates how trigonometric parallaxes, standard candles benefit us in determining the huge distance of objects even numerous billion light years away from Earth.
