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.

Get ready for the great planetary alignment February 28th!

February 27, 2025

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!

Japan launches world’s first wooden satellite

November 12, 2024

Researchers at Kyoto University who developed it hope it may be possible in the future to replace some metals used in space exploration with wood.

The researchers argue that “if” trees could be planted on Mars…

OK, just stop right there. I’m pretty sure Mars will struggle to support even grass, let alone trees.

And the argument that, due to a lack of oxygen, flammable wooden structures in space would not be in danger strikes me as a bit ludicrous…surely there would be oxygen inside the wooden structures?

And, you know, I do think I’ve seen this before some where…nah…

Interstellar! If only…

According to Thorne, who served as a consultant on the science of Interstellar, quantum mechanics could hypothetically explain a way to time travel via wormhole. So far, it’s a thought experiment that leads to the conclusion that you’d lose information along the way—not very practical.

First off, I’m incredibly annoyed at the way WordPress has screwed up the “quotation” function. It seems they are more focused on encouraging bloggers to use AI to write.

Uh. I don’t need AI. I blog. The end. WTH is the point of using AI to write my thoughts? It’s already being trained to USE my blog in the first place! Idiots.

OK. Second, the Popular Mechanics article I’m linking to is entitled “Interstellar travel is possible if we break into a higher dimension, scientists say.”

Only, that is NOT what scientists say. It’s still a thought experiment!

Chinese scientists “create” water from lunar soil

Using the new method, one metric tonne of lunar soil will be able to produce about 51 to 76 kilograms of water, equivalent to more than a hundred 500-millileter bottles of water, or the daily drinking water consumption of 50 people, the state broadcaster said.

The soil was from the 2020 expedition, which was the first in 44 years to bring back soil from the Moon.

Considering all of NASA’s problems, it looks like China will have a moon base years before the US does…and probably in prime resource locations as well.

And don’t forget that the hydrogen in the soil can also be used for rocket fuel. It would be a lot easier to launch ships to Mars and beyond without having to deal with Earth’s gravity…

Winner of “Best Short Story – Sports”! 🥇

MThomas

My short story “Two Strikes Against” was selected as the Winner in the inaugural Next Generation Short Story Awards! (Official list to be available next week.) UPDATED: Link here https://shortstoryawards.com/winners.php?year=2024

Basically it’s a story about a Japanese baseball player on Mars, with a twist. It got rejected a couple of years ago by several scifi magazines, so I figured why not try the sports category.

Especially since there was no scifi category.

Just grateful and thankful for the award. I hope you all get a chance to read the story!

(FWIW “Marsball” is mentioned by characters in an early chapter of Bringer of Light. In fact, I was going to call the story that. Very glad that I didn’t in the end!)

Now available! Bringer of Light

Bringer of Light: Locations video

This time I figured out how to import the slides directly into mmHmm, and I managed to update my MacOS to Sonoma, which allowed me to use my USB mic (yay). But I also called Ceres a “moon” at some point (it’s not a Moon but a dwarf planet in the asteroid belt near Mars). Oops. Not enough time to edit that bit out or record it again, so just word to the wise! Always fact-check videos, folks. Enjoy!

Bringer of Light – pre-order now!

Water molecules detected on the surface of an asteroid in space for the first time

March 13, 2024
MThomas

Water molecules have been detected in asteroid samples returned to Earth, but this marks the first time that the molecules have been discovered on the surface of an asteroid in space. The team studied four silicate-rich asteroids using data from the now-retired Stratospheric Observatory for Infrared Astronomy(SOFIA).
https://www.popsci.com/science/water-asteroid-space/

The asteroids in question are Iris (124 miles / 200 km in diameter) and Massalia (84 miles / 135 km). Both are in the asteroid belt between Mars and Jupiter. Iris is about the size of the US state of Maryland, while Massalia is roughly the size of Connecticut.

Note that the same observatory also found water on the Moon, about a “12-ounce bottle” worth. Not nearly enough for a settlement, but where there’s surface water (albeit trapped in soil on the surface), there’s likely to be more underneath.

(See also https://www.swri.org/press-release/swri-scientists-identify-water-molecules-asteroids-the-first-time — the PopSci linked article above essentially plagiarised almost its entire text. Bad scientist, bad.)

Original article here: Arrendono et al. (2024) Detection of molecular H20 on nominally anhydrous asteroids. Planet. Sci. J. 5. 37 doi 10.3847/PSJ/ad18b8 – good luck trying to read it!
