The Cassiopeia A supernova remnant glows in X-ray, visible, and infrared light in this Jan. 8, 2024, image that combines data from NASA’s Chandra X-ray Observatory and Hubble, Webb, and Spitzer space telescopes. A study by the XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft has made the first-ever X-ray detections of chlorine and potassium from the wreckage; a paper about the result was published Dec. 4, 2025, in Nature Astronomy.

Hubble, Webb Sure Gets A Lot Of Great Photographs & Videos From "FAR OUT" There, But
Those Chemicals Are Readably Available In Our Las Vegas Tap Water, But Too Much Chlorine,
We're Supposed To Be Able To Drink It, Not Add To Our Swimming Pools

Lt Col Charlie Brown astronomy is not one of my "Jack of all trades" skills. So can you tell me how this phenomenon, nebulas, objects that take shape in the presence of infrared lights, etc.?

Most Of Us Are Lacking In Knowledge When It Comes To Outer Space,
But We Just Don't Admit It In Front Of Everyone, - So "Shhh" Keep Our Secret.-

Hey Phyllis, I am no expert but basically when you shine Infra red light through a cloud of gas, any molecular bonds show up on a spectroscope as a frequency peak or valley. And that correlates to what the bonds are in that molecule. And those bonds are well known, so they can tell which molecule is present like Potassium or Chlorine. They have truly remarkable sensitive instruments that can do this sort of Atomic Chemistry at a distance.
So the most common element in our Universe is Hydrogen. Everything you see around you starts with that. The Heavy Elements are all made in Stars: Nickel, Iron, Gold etc...and some are made in the hot Plasma blowout from a star. Hence the saying that we are all Star Dust. It really is fascinating to trace the elements back to (get the pun, trace elements LOL) to the Early Universe when the different types of Hydrogen ruled. Hope that helps.

SGT Kevin Hughes it does. As you know my son loves science, so I am going to show him this post.
