A little over a week ago, scientist published a detailed analysis of Vega's surprisingly planet-free debris disc. Vega, one of the brightest stars in Earth's sky, may have planets: but the October 31 paper rules out any Saturn-size or larger worlds in wide orbits. That reminded me of a Sherlock Holmes quote: "'Is there any point to which you would wish to draw my attention?' 'To the curious incident of the dog in the night-time.' 'The dog did nothing in the night-time.' 'That was the curious incident,' remarked Sherlock Holmes." ("The Memoirs of Sherlock Holmes", " Silver Blaze " , Arthur Conan Doyle (1894) Via Gutenberg.org) More to the point, not finding planets in Vega's debris disc should help scientists learn more about how stars and planets form. And gives me something to write about. Vega Debris Disc: "Smooth, Ridiculously Smooth" Dust, a Gap, and — the "Poynting-Robertson Effect...

"...All of us dwell under the same sky. All of us are moved by the beauty revealed in the cosmos and reflected in the study of the heavenly bodies and substances. In this sense, we are united by the desire to discover the truth about how this marvellous universe operates; and in this, we draw ever closer to the Creator...." ( Address to Participants in the Summer Course of the Vatican Observatory , Pope Francis (June 11, 2016)) My interest in science started as a fascination with dinosaurs. By the time I left high school, that fascination included astronomy, physics, cosmology, and more. My academic specialties were history and English, but I never lost my intense interest in pretty much everything else. That didn't change when I became a Catholic — partly because where my faith is involved, paying attention to the wonders and beauty surrounding us isn't a problem.

We've known about “black hole jet systems” for some time, but never one as big as Porphyrion: a 23,000,000 light-year giant.

A long time ago, some folks were — apparently — living happily in the Rhône River Valley. Whether or not they were happy there, we've found evidence that they stayed near what we call the Grotte Mandrin for 50,000 years. And that they somehow managed to keep newcomers from disturbing their solitude: and isolation. Idyllic as that may seem, keeping themselves free from what my culture called miscegenation may explain why Neanderthals aren't part of today's world. Not as identifiable individuals, at any rate.

I take commercial puffery with a grain of salt, but that 2,492 carat diamond from the Karowe mine does seem "epic".

A paper published this month doesn't so much tell us what's inside a neutron star, as show what's not inside. Considering how little we know about these immensely-dense stellar objects, that's a significant step toward understanding the things. I'll take a look at that, but mostly I'll be talking about what we've been learning, and why I think paying attention to this wonder-packed universe is a good idea. Even if — maybe because — this Haldane quote, written a few years before we knew about neutron stars, still reflects how God's universe has been surprising us. "Now, my own suspicion is that the universe is not only queerer than we suppose, but queerer than we can suppose…." (" Possible Worlds and Other Essays ", p. 286, J. B. S.

Headlines about an "eyeball planet" got my attention last month. Then I got distracted by what I thought were more time-sensitive topics — and remembered what two scientists learned when they simulated ocean currents and winds on a tidally-locked exoplanet. That last item was from 2013. It's still the best discussion I've seen of what an "eyeball planet" might actually look like. Turns out that a patch of open ocean on a tidally locked exoplanet's ocean wouldn't necessarily be circular. But I'll admit that "eyeball planet" is a cool description. And may be easier to remember than terms like "lobster-like spatial pattern". So this week I'll be talking about LHS 1140 b, which may not be an "eyeball planet" after all, ocean planet simulations; and — briefly, for me — how I see extraterrestrial life.

I remember when many folks were getting used to the idea that space travel wasn't just science fiction. Some apparently still haven't gotten the memo, but others have been developing new technologies. Like inflatable space stations. I'll be talking about that, and how I see getting back on the road to the stars. Building Better Habitats: Basket-Weave, and Now: Isotensoids? "...strong, simple, and safe...."

I look at that, and where we can be going.)

Folks living in the Caribbean, Yucatan Peninsula, and south Texas are cleaning up after Hurricane Beryl. Some are also mourning those who didn't survive the storm. I haven't been personally affected by Beryl, although my in-laws are in Louisiana, next state over. They seem to have been away from the worst weather, for which I'm grateful. This week I'll take a quick look at what happened, what the storm doesn't mean, and — as usual — whatever else comes to mind.

I haven't researched it, but I'm guessing that 'animals are conscious' headlines peaked about two months back. " If Animals Are Conscious, What about Us? " Crawford Kilian, The Tyee (April 29, 2024) " Scientists push new paradigm of animal consciousness, saying even insects may be sentient " Evan Bush, NBC News (April 19, 2024) " It's 'irresponsible' to ignore widespread consciousness across animal world, dozens of scientists argue " Saul Elbein, The Hill (April 19, 2024) "Animal consciousness" makes more sense than some headlines suggest — so this week I'll be talking about new research, old ideas, and how I see being human.

It's been 30 years since a Mexican theoretical physicist said that a warp drive was possible: hypothetically. And published math that backed up his claim. Last month, a team of scientists showed how we could build a warp drive: again, with math backing up their claim. This year's variation on the Alcubierre drive couldn't travel faster than light. But it can, they say, be built with materials we have today. This is a very big deal. And it's what I'm talking about this week. Along with whatever else comes to mind.

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.

UPDATE/FIX — The links in this post now take you to "Kamoʻoalewa: Breakaway Asteroid and Quasi-Moon" on A Catholic Citizen in America. I goofed when posting this preview - - - sorry about that: and have a good day/evening/weekend/afternoon.... :) The asteroid 469219 Kamoʻoalewa isn't exactly Earth's second moon. But it's been circling our world for centuries: and near Earth's orbit for much longer. Now scientists say they've traced the asteroid back to Giordano Bruno crater on the Moon. I'll be taking a look at what I could find of their research, Earth's moons, and asteroids whose orbits keep them near Earth.

Next week's total solar eclipse won't be total here in central Minnesota. I'm not terribly disappointed, since the odds are that I couldn't see it anyway. There's rain in the five-day forecast. We need rain a great deal more than I need to see a total eclipse of the sun, so I've got at least two reasons for not being terribly disappointed.

Wood generally doesn't last long if left out in the open. That's why finding interlocking logs near the Kalambo River is such a big deal. Well, part of the reason. They've been submerged, it that's the right word, in wet sediment. For something like a half-million years. Which makes them part of the oldest known wooden structure.

When I saw "epic importance" and "fossils" in the same headline, I figured whatever'd been found would be at least somewhat out of the ordinary.

Last month ended with headlines hinting that our first glimpse of extraterrestrial life was just around the corner. " Discovery Alert: A ‘Super-Earth’ in the Habitable Zone " Pat Brennan, NASA News (January 31, 2024) " Scientists More Hopeful Than Ever That Perseverance Has Already Found Life on Mars " Carly Cassella, ScienceAlert (January 24, 2024) A week later, there's the usual politics and pandemonium in the news: but no space aliens.
