The Lives Of The Stars

Well, I’m back from the visit to the preview of the Griffith Observatory that I mentioned to you I was going to. It was a rather good visit. They organised it well, and -boy!- have they done a great job on the restorations! I’ll try and assemble the several pictures that I took into some sort of narrative for you, and report soon. While you wait, here’s one of my favourites:

main sequence exhibit

This is particularly poignant, in my opinion. The children are looking at the lovely exhibit of the life stages of stars. You can just see the line of what is called the “Main Sequence”, a line [along] on which most stars [move through their life] end up for most of their life, on a “Hertzsprung-Russell” chart of colour/temperature horizontally vs brightness/luminosity vertically. Here’s a nice chat about the lives of the stars at NASA.

I’m a sucker when it comes to pictures of children learning… I don’t know why.


(A commenter called “supernova” correctly refined my statements above. Thanks!)
