This month's analysis of a piping hot Super-Earth's atmosphere is a big deal. But it's not the "first" detection of a terrestrial exoplanet's atmosphere, not by about eight years. 1 I'll be talking about how scientists sift through data, 55 Cancri e's atmosphere, its planetary system, why 55 Cancri e — the exoplanet was officially named Janssen in 2015 — and why calling Janssen a "diamond planet" may be appropriate.

They were looking for supernovae. What they found may become a double planet, like the Earth-Moon system, once it cools down. Or a planet with a giant moon, again like the Earth-Moon system. Then again, an oddly-uneven dusty disk may be orbiting this young, very "Sun-like" star. Either way, ASASSN-2qj is much more interesting than it was a few years back. strong>Barycenters and Binaries: Briefly Rabbit Holes and an ‘Assassin Star’ Professional Scientists, Amateur Astronomers, Teamwork and Twitter/X "...So Slow Smart" ASASSN-21qj: Once Obscure, Now Intriguing A Very Sun-Like Star Uncertainty and Science '...A Star to Steer By...'

As I've said before, this isn't the world I grew up in. Back then, the Solar System had nine planets, assorted moons, and asteroids. Plus, of course, the sun. Now we've got planets, dwarf planets, minor planets, natural satellites, trans-Neptunian objects, plutoids, comets, centaurs, and small Solar System bodies. Just to keep things interesting, definitions for the new labels overlap. Some labels, like plutoids, didn't catch on; and it all keeps changing as we collect more data. This week I'll be talking about sednoids, another subset of trans-Neptunian object; 1 along with whatever else comes to mind. "All the News That's Fit to Print" — and Some That Isn't 'COMET PILLS!

Nerd alert! This week I used words like deuterium and magnetohydrodynamics. And I may have gone into more detail that necessary about why we didn’t have fusion power generators in the 1960s. A British company's plans for test-firing a fusion rocket engine got my attention last week. I'd planned on writing about it then, but a dental procedure and household matters got in the way. So I researched and made more notes over the weekend, and when my town's power came back online late Monday afternoon: the notes weren't there any more. That's something I may talk about, sometime next week. Anyway, I re-researched, got stuck and/or distracted a couple times — I'll talk about tralphium and mindsets in a bit — and ended up with this post. Which, as it turned out, included a bit about NASA's interest in UAPs and the serious search for extraterrestrial intelligence.

TThis week, I'll talk about Professor Ethan Siegel's view that "the myth of the super-habitable super-Earth planet" is "a scientific catastrophe", other non-catastrophes; and a problem with "super-Earths" as a label. Along the way I'll look at science, news, headlines and silliness. And finally, skip lightly over a 13th century academic debate that got out of hand. "...A Scientific Catastrophe"?

There may have been times when one generation's world was much like another's. This is not one of those times. Science textbooks of my youth included speculation that Earth's mountains exist because our planet has been cooling and shrinking. One of my geology professors didn't "believe in" continental drift, and that's another topic. Back then, we knew that planets orbit our star, but weren't sure how the star we call the Sun and the Solar System formed. We still don't, for that matter. Not for sure. But the nebular hypothesis, or something very much like it, is a pretty good fit with observations. I'll get back to that, and some of what we've been learning about planetary systems: including TRAPPIST-1 and its seven worlds. More at A Catholic Citizen in America .

Venus is dead as a doornail as far as life is concerned. Life as we know it, at any rate, and already I'm drifting off-topic. Geologically, though, we've know that there's still metaphorical life in Venus. Or was, until very recently. Orbiters have sent back evidence of geologically-recent volcanic activity, including images of shield volcanoes and lava flows. But we had no direct evidence of a volcano that's active now.

...The Webb data had already been used in 21 research papers, back in February. I'd prefer looking up a few of them, picking out one that sounded interesting, and talking about it.

Monday afternoon was sunny and warm. For central Minnesota in January. The high was around 32° Fahrenheit, 0° Celsius. Our sidewalk and driveway were free(ish) of snow, with a bit over a half-foot covering the yard. The weather station at Sauk Centre Municipal Airport was back online Thursday afternoon, and then the National Weather Service posted a Winter Weather Advisory for this area. Sauk Centre Municipal Airport isn't in the Chicago O'Hare class. But with two runways, hangar space for 11 private aircraft, a fuel pump and a private airplane maintenance facility, it meets our needs. Granted, one of the runways is a grass surface marked with yellow cones. I don't know if it's usable in winter. And that's another topic.... More at A Catholic Citizen in America .

Scientists in Sweden, taking part in 2019's BEAST program that used SPHERE on the VLT discovered an 'it might be an exoplanet.' In 2021, they got confirmation. They'd spotted an exoplanet. And SPHERE on the VLT 1 has an picture of the newly-discovered world. I'd planned on talking about BEAST, SPHERE, VLT; comparing ground-based and space observatories; and whatever else came to mind. Then, on Tuesday, I started running a fever. It was of the 'nothing serious' variety, but quite enough to slow me down. After that, the household got a brief visit from number-two daughter, son-in law and granddaughter: a happy occasion. Which also didn't help me do what I'd planned. So I trimmed my plans back to what was possible, and this is the result. b Centauri(AB)b, AKA HD 129116 b: Big Bright Stars and a Big Mystery Planet (From ESO, used w/o permission.)

Designations like HD 63935 b and c don't exactly roll of the tongue. Although with a little work I might pronounce them "trippingly on the tongue," as Hamlet put it. Maybe saying "sixty five ninety three five bee and cee" would do the trick. Then again, maybe not. I thought, briefly, of calling HD 63935, HD 63935 b and HD 63935 c "Sam, Fred and Chuck;" but thought better of it. At any rate, I'd been catching up on 'exoplanet' notes from the last year or so when I read about the HD 63935 planetary system. HD 63935's known planets there, sub-Neptunes, should help scientists learn more about how planets form. Or, rather, observing them and analyzing those observations should....

We haven't found extraterrestrial life. But we're still finding planets circling other stars. Thousands of them. Some of those planets couldn't possibly support life as we know it. But some might. Atomic oxygen may be a good biosignature: evidence of life. That's what some scientists said in a recent paper. If they're right, we may be a step closer to finding life in this universe.

We've known about 55 Cancri e since 2004. It may have lakes and rivers of lava. But that's probably not what keeps its night side hot enough to melt copper. Ross 128 b, discovered this year, is a bit more massive than Earth, warm enough for liquid water, and too hot. It's not quite 'Earth 2.0,' but it may support life....

This universe is bigger and older than some folks thought, a few centuries back. I don't mind, at all. Besides, it's hardly new information. We've known that we live in a big world for a long time.

We could detect oxygen in Proxima Centauri b's atmosphere. It's a biosignature, but not proof of life. Some extrasolar planets are like Earth, almost. Many are unlike anything in the Solar System.

The world didn't end last Saturday. That's nothing new, and neither is another fizzled End Times prediction.

I'll also take a look at the continuing, and serious, search for Planet 9; predictions involving close encounters of the cometary kind; and what we're learning about the outer Solar System....

I nearly missed an interesting development in SETI, the Search for Extraterrestrial Intelligence. Interesting, and as newsworthy as most Stephen Hawking stories, but probably not significant. Professor Hawking didn't start chatting with aliens over the Labor Day weekend. That would be major news. But an outfit he's connected with will be listening to FRB 121102. I think it's likely that they'll collect useful data, and that this isn't a prelude to 'first contact.' Other scientists say they've spotted several planets orbiting Tau Ceti. Two of them may be just inside that star's habitable zone. More at A Catholic Citizen in America .
