It's been two and a half weeks since NASA's "Public Meeting on Unidentified Anomalous Phenomena", aired on YouTube. Or is that streamed on YouTube? Never mind. The NASA panelists did not announce contact with an extraterrestrial diplomat, or admit that they've been holding space aliens captive. So some of the folks who were contributing to the video's live chat were profoundly disappointed. The panelists did, however, discuss what Unidentified Anomalous Phenomena (UAP) means, how they'll be collecting and analyzing data, and answered some questions. Ideally, I'd have listened to all four hours of the meeting, pondered its content, and would now be sharing the highlights. That didn't happen. But I did catch bits and pieces of the video: mostly during the last hour. So I'll be talking about that today, focusing on a former pilot and astronaut's experience: along with flying saucers, ball lightning and (very briefly) space aliens.

When I started writing this, I'd planned on talking about WASP-18 b, a hot Jupiter: how we've found water in its atmosphere, and something odd about the planet's temperature on the edge of its sunlit side.

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"?

Nations and organizations running the International Space Station agreed to keep supporting it until 2030. That's what I'll be talking about this week. Along with why the ISS won't last forever, plans for either ditching it in the South Pacific or starting an orbiting salvage yard, commercial space stations and something my oldest daughter and I thought of.

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 . (New planetary system pattern discovered. TRAPPIST-1 worlds. Solar System formation and evolution ideas, from Descartes to pulsar planets. Psalms 115:3.)

The TRAPPIST-1 planetary system is news again, this time because we've taken the innermost planet's temperature. That, by itself, isn’t newsworthy. We've been using infrared observations to learn how hot exoplanets are at least since 2006. 1 What makes the latest observations special is that they’re the first time scientists have measured a comparatively small, cool exoplanet's temperature.That's what I'll be talking about this week, along with whatever else comes to mind.

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.

Betelgeuse, the bright red star in Orion's right shoulder, is a semiregular variable star, with small periods of 185 days and 2,100 days and a main period of around 400 days. It will explode at any moment, and we're right next door. If I had any sense, from one viewpoint, I'd talk about the ozone hole, denounce forever chemicals and promote a 'Save the Panda' fund I'd set up. Or maybe indulge in free association inspired by Revelation and Gematria, and slip in hints that your only hope is to give me money. Yeah. That kind of trouble I don't need. Besides, I suspect the weird mix of numerology and Bible trivia that infested 'Christian' radio during my youth is no longer in vogue. 1 So instead, I'll look at the last two times Betelgeuse was newsworthy. Then I'll talk about cosmic scale, stars and whatever else comes to mind. Headlines! Science Distances, Safe and Otherwise Estimates and an Example Looking Ahead, Looking Back

Gene-editing rules showed up in my news feed last Monday. So, indirectly, did genetically-edited twins who, as far as I know, are still alive. If I'd known how little I'd be able to verify about Dr. He Jiankui's famous (or infamous) twins, maybe I'd have picked another topic.

...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.

It's been a little over 10 years since scientists spotted Kepler-22 b. It was the first time we'd spotted a transiting exoplanet that's in its sun's habitable zone. That may or may not mean that Kepler-22 b is habitable. The odds are good that the exoplanet is a water world: covered with an ocean far deeper than Earth's Since then we've discovered quite a few water worlds. And, possibly because there's a 1995 action film called "Waterworld", they're often called ocean worlds. 1 This week I'll talk about two (probably) ocean worlds, Kepler-138 c and d; discovered in 2014, they're far to hot for life as we know it. But scientists recently published a new analysis of those two worlds. And that gave me something to talk about. So did a proposed change in when taxpayer-funded research projects release data. It's good news or bad news, depending on who's talking. That's this week's first item. I'll also look at

We've found two new worlds, GJ 1002 b and c, that could be habitable. They're the right size and most likely around the right temperature. Actually, make that three new worlds. Another one, Wolf 1069 b, showed up in my news feed as I was writing this. 1 But Wolf 1069 b will wait for another time. What with one thing and another — including an unexpected visit from a daughter, son-in-law and granddaughter — I didn't ramble on as much as usual this week. So I'll take a brief, for me, look at GJ 1002 b and c. And I'll talk about literally cool data from the JWST: a look at ingredients for "the building blocks of life" in the Chamaeleon I dark molecular cloud. More at A Catholic Citizen in America . (GJ 1002 b and c may be habitable worlds orbiting a nearby red dwarf. JWST gives us new data about CHONS: key elements in the building blocks of life.)

As I write this, scientists have not made contact with an extraterrestrial civilization, cured the common cold, or developed a process for using pocket lint as a pollution-free sustainable energy resource. So I'll be looking at galaxies, black holes, and a place where stars are forming. Scientists figure that last item will help them work out how the earliest stars formed. But first, NASA's APOD (Astronomy Picture of the Day), almost five years back. Make that pictures: of the Cartwheel Galaxy Region and HST WFPC2. More at A Catholic Citizen in America .

Kepler-1658 b, KOI-4.01, is a "hot Jupiter". In another 2,500,000 years, give or take a bit, it won't be there any more. That makes it a hot subject for scientists: literally and figuratively. Kepler-1658 b is also the the Kepler space telescope's first confirmed exoplanet. ... ... today I'll be talking about Kepler-1658 b and why studying it matters. To scientists, at any rate....

I'd been planning on writing about chimps, strength, muscles, and assumptions this week. Then, a few hours later, I noticed that I'd been talking about horses, digestion, etymology, cephalic index and other assumptions. Which, for me, is about par for the course.

It's been a while since I talked about what I'm doing here and why I'm doing it. And even longer since I talked about Nancy H. C. Ward's "Sharing Your Catholic Faith Story: Tools, Tips, and Testimonies." The book's a big deal for me, since it's the first time I wrote for the Red River Valley Historical Society’s Heritage Press that I've had an in-print byline. More to the point, as Lisa Hendey said, it's "an enjoyable template for the challenge of evangelization." So today I'll talk about social media, evangelization, science, history, art, "Sharing Your Catholic Faith Story" and why I post something here weekly. Not necessarily in that order.
