Geminids, Geminids, Geminids!

December 15, 2025

It’s been several months since I last posted…too much work and no play!

Until this past Sunday. Whew.

After a morning lecture about ancient Japanese myths and “deliberately forgotten” kings (maybe), I was grateful to be able to take a quick power nap…

…so that the family could go up a nearby mountain and watch the Geminid meteor shower. (By “mountain,” I mean about 640m/2100ft.)

After a brief lecture/quiz by a staff member at our local culture center, we stayed outside, lying flat on the ground, for over an hour. And, yes, it was cold, despite the sleeping bag and thermal underwear. I saw three shooting stars. Not nearly as many as I’d hoped.

After we got home and took evening baths, the kids went out on our second-floor balcony and found out that the night view was even better at home than on top of a mountain! At least they knew what to look for, thanks to the culture center event.

Although the peak is Sunday night between midnight and 2 a.m., the meteors are still visible to some degree the rest of this week.

And by “meteor,” I mean the size of grains of rice. Look to the eastern sky, just a bit to the northwest of Orion, to find the Twins (Castor and Pollux in Greco-Roman mythology).

For more on the origins of the Geminids, check out the JAXA mission to Phaeton, the parent body asteroid. It’s DESTINY!

Life on Trappist 1e?

September 12, 2025

In two separate papers published Monday in the Astrophysical Journal Letters, astronomers zeroed in on the TRAPPIST-1 system, which consists of seven rocky planets that orbit a single star. Both studies outlined initial results from observations by NASA’s James Webb Space Telescope, suggesting that one planet in particular, known as TRAPPIST-1e, may have a nitrogen-rich atmosphere like Earth’s, though follow-up studies are needed to confirm the discovery.

Trappist 1e is in the “Goldilocks zone” in orbit around its star (i.e., not too cold, not too hot, just right). However, the Webb telescope can’t determine whether its atmosphere has any carbon dioxide, hydrogen, or oxygen, only nitrogen. Yet nitrogen is a clear sign that life is possible, because without nitrogen, DNA and other proteins are not possible. Of course, it could be simply a whole lot of microbes. Or even just ammonia.

Closer to home, the Mars rover Perseverance has found evidence of life in the distant past. Maybe. It found evidence that certain rock features may have happened because of microbes.

May.

That’s how science works, folks. A whole lot of maybes.

(I still think we need more catchy names for the Trappists. I mean, come on.

Ghosts in the family tree — Abigail West

I wrote some time ago that there was a ghost in the family.

I guess it’s finally time to write about it. Sorry for the wait! Maybe I should hold off on this until Hallowe’en…

How Star Trek helped NASA make better shuttle names

August 8, 2025

Gorog summarised in the memo:

  • This group comprises millions of individuals who are deeply interested in our space programme
  • The name “Enterprise” is tied in with the system on which the Nation’s economic structure is built.
  • Use of the name would provide a substantial human interest appeal to the rollout ceremonies scheduled for this month in California, where the aeronautical industry is of vital importance.

It is really too bad that the shuttle looked nothing at all like the Enterprise (Constitution class).

And an odd coincidence that the original name chosen by NASA was…

…Constitution…

How to clean your glasses (yawn)

Daily writing prompt
Scour the news for an entirely uninteresting story. Consider how it connects to your life. Write about that.

Seriously, this is an “NBC Select” article: https://www.nbcnews.com/select/shopping/how-to-clean-your-glasses-rcna175677

I wear glasses. I have worn glasses since I was in elementary school 2nd grade — the “aviator” style made of cheap plastic that I frequently broke during recess kickball games and then had to tape together so I could wear them.

I have never figured out how to keep my glasses clean in the subsequent four+ decades of my life.

But I seriously doubt this is “newsworthy.” Cringeworthy, maybe.

Nineteen years ago, my wife and I went to Hiroshima by high-speed ferry boat, on our way back from visiting her parents in Kyushu. Her father’s family comes from Hiroshima (although her father was actually born in Dairen/Dalian (大連), China) and her uncle and his family still live about an hour’s drive north of the city.

(Update from 2020: We visited Hiroshima with the kids for the first time last January, for New year’s 2023.)

It was my first time to visit the Hiroshima Peace Memorial Museum. We arrived about a week after the annual Peace Memorial Ceremony and Peace Message Lantern Floating Ceremony, but the museum was a very sharp reminder of the horror that my country visited upon Japan.

ChatGPT is frighteningly good at writing literary analysis…

🧾 Conclusion

Adam’s Stepsons takes the core questions of Blade Runner and distills them into a tight, character-driven drama. It lacks the sweeping visuals of Villeneuve or the noir cityscape of Scott — but it delivers something arguably more intimate:

A quiet horror — and quiet triumph — in the collapse of identity, where the artificial doesn’t just mimic life…

It replaces it.


Over the weekend (my first with no student work to grade — finally! — since April), I decided to ask our “old” friend ChatGPT if it could analyze my sci-fi novella Adam’s Stepsons. Really, I was just curious what it would say.

It said…a LOT.

It correctly interpreted the title (something that many readers apparently didn’t get). It correctly identified the main themes as part of a “post-humanism” sub-genre of science fiction. And once I gave it three short excerpts (from the near the end of the story), it gave a frighteningly accurate thematic and symbolic analysis of the entire novella…just from three short excerpts of a total of about six pages.

I won’t copy all it gave me (you all can go try on your own and see what it says!). But let me share what the program thought were key themes:

Long time, no…

Hi, everyone. I haven’t written a blog post in a very long time.

For various reasons.

I’ll see if I can start posting a few entries on recent science events in a few days (for starters, four astronauts finally arrived at the ISS, the first replacements following the Boeing Starliner fiasco).

But for right now, I want to follow up this short post with some analysis I got from our friend ChatGPT…

…about Adam’s Stepsons and Bringer of Light. Stay tuned!

Get ready for the great planetary alignment February 28th!

Note: Planets do not line up like this…

The best day to see all seven major planets (yes, you read that right, all seven!) is Friday, February 28th.

The link will describe (and give pictures) of where to find them all in the night sky.

Finding Orion is the key to most of them. Knowing where the Pleiades are helps, too.

The next time this “parade” appears will be 2040, so fingers crossed for clear skies!

Hi, everyone. I know I haven’t posted in a while now (about three months).

Things happened. I’ll see if I can deal with that in a post this weekend before returning to regularly blogging about astronomy and etc.

Winter is still here! (In the northern hemisphere.) Going on walks and hiking in 3C windy weather only makes hot chocolate taste that much better…
