How are stars made? You know, those celestial bodies illuminating the sky, happily burning until they get tired of that and become star dust, the components of which we are made.

“The cosmos is also within us. We’re made of star stuff.”

— Carl Sagan

Check out this simulation of a star forge.

If this is the forge, is dark matter the anvil?

How do stars form? Most form in giant molecular clouds located in the central disk of a galaxy. The process is started, influenced, and limited by the stellar winds, jets, high energy starlight, and supernova explosions of previously existing stars. The featured video shows these complex interactions as computed by the STARFORGE simulation of a gas cloud 20,000 times the mass of our Sun.

I’m also making today, although nothing as dramatic as stars. More like yogurt, a project that required the sewing machine, and a hack for our leaky dishwasher (yes, another appliance is on the road to obsolescence; they really don’t make them like they used to).

I’m also heading into the workshop to make things out of wood. Well, to remember how to make things. And find my tools. And my respirator. And my wood turning clothes. It’s been a while (thanks, Covid)!

My projects won’t be as dynamic or lovely as a star (or Chopin’s music, for that matter).

I’ll still try.

After all, I want to do my ancestors proud.

Now might be a good time to spend a little time with everyone’s favorite physicist, Neil deGrasse Tyson, as he revisits the origins of the atoms that make up the human body.

From stars we came and to the stars we must return.
