About this document
Estimating Speeds & Distances in Astronomy by Dulce J. Luaton is a document available to read on EtoBox.
The document provides information about estimating the speeds and distances of far-off objects using the Doppler effect and cosmic distance ladder. It discusses how the Doppler effect is used to determine velocity and how the cosmic distance ladder uses different objects as "rungs" to measure increasingly distant objects. It also summarizes evidence that the universe is expanding, such as distant galaxies moving away from us and the abundance of light elements, and explains how the expansion of the universe
