Description
The Hertzsprung-Russell diagram is an incredibly useful device for learning about populations of stars. However, sometimes students can get confused by it, thinking that the diagram represents stars moving through space. There are a number of web sites (some with animations) that can help you visualize what the H-R diagram can be used for. Here's one to get you started:

Your task for this week's discussion board is to find another site that explains some aspect of the H-R diagram (or, it can just be a site that explains some part of stellar evolution). Post the link. Then, explain something about the H-R diagram and/or stellar evolution that this site helped you learn and/or that you find interesting.
-Your initial post should be at least 250 words.
-Respond to at least two other students

The H-R diagram
In the early 1900s, Ejnar Hertzberg and Henry Norris Russel independently developed
the Hertzsprung- Russell diagram (H-R diagram). In the study of stellar evolution, the H-R
diagram presents a crucial tool. H-R diagram can be used for theoretical or observational
purposes. In the theoretical perspective, the H-R figure examines temperature of stars against
their luminosity, while in observational perspective; the figure plots the colour of starts against
their outright magnitude (Cosmos, 2019).
Interestingly, the H-R figure allows astrono...
