Lesson 7 Lab: Cosmic Distance
Ladder
Lesson 7 Lab: Cosmic Distance
Ladder introduces a few of the primary
methods used by astronomers to determine astronomical distances. Parallax is
introduced first, spectroscopic parallax, main sequence fitting, variable
stars, and supernova are all discussed. You will see how some of these methods
are used to measure the distances to nearby stars while others are used to
determine distances to very distant galaxies.
The Cosmic Distance Ladder Module consists of material on seven
different distance determination techniques. Four of the techniques have
external simulators in addition to the background pages. You are encouraged to
work through the material for each technique before moving on to the next
technique.
Getting started with Lesson 7 Lab: Cosmic Distance Ladder:
·
First, select the following link and
work through the background sections on Radar Ranging, Parallax, Distance
Modulus, Main Sequence Fitting, Supernova, Cepheids, and Hubble’s Law under the
‘Main Content’ section at:
Next, open the Parallax Explorer Simulator, and
familiarize yourself with the capabilities of the Parallax Explorer Simulator
through experimentation. You will also be using the following simulators:
o
Supernova Light Fitting Curve Simulator
o
Spectroscopic Parallax Simulator
After familiarizing yourself with the
simulators interactives, follow instructions and answer questions in the Lesson 7 -
Lab Cosmic Distance Ladder Worksheet.
Note: The Lab Simulators require Flash Player which is integrated into
Windows 10 and work best with Internet Explorer (IE). To avoid technical issues
IE is recommended for running the simulations. If you try another browser you
will need to set up flash player options for that browser yourself. For
example, if you are using Chrome, go to the upper left of the URL browser
entry, select "Not Secure" then select "Allow" to give
Chrome permission to open the simulator.

Select the Lesson 7 Lab: Cosmic Distance
Ladder link above. Then answer the questions
using your worksheet.
Labs do not have a time limit but are due on the due date of the lesson
posted in the Syllabus Page 2.
