Sorry for the delay, everyone—I know I said you’d have a post on Sunday, not Tuesday, but I cut myself while opening a new set of knives and had to get stitches. I still don’t have full use of my finger—it’s got an annoying gauze bandage that makes it…

I often refer to what we call the interstellar medium as the galaxy’s “backstage,” and I do that for a reason: for the most part, we can’t see it. The backstage of any theater isn’t part of the show. You, as part of the audience, never see it. But you see…

Take a wild guess: What do you think this image is showing you? If you said it looks like a giant black hole in space, I don’t blame you. I also don’t blame you if you thought it looks like a giant outer space blob…and the funny thing is, that’s actually…

What you see here is the Trifid Nebula, a vast cloud of gas and dust in space. In my last post, we explored why it looks the way it does. We discovered that the pink hues of emission nebulae are caused when extremely hot nearby stars “excite” the gas of…
