Richard Stallman sez we should call it ‘PI’ … pretend intelligence.

I remember Angela Collier talking about this topic, but basically: the “AI” in question is a different beast from the “AI” in chatbots and image generators. The underlying tech is the same (artificial neural networks), but instead of making the bot mimic human output, you’re asking it to point out stuff.

So for example, you feed it with two sets of data:

  1. a bunch of pics of completely normal astronomical objects
  2. a bunch of pics of anomalous astronomical objects

Then you “ask” the bot to assign new pictures (not present in either set) to one of those sets.

In my opinion it’s one of the best ways to use the new tech. If there’s a false positive, nobody is harmed — the researcher will simply investigate the pic, see there’s nothing worth noting there, say “dumb clanker”, and move on. Ideally you don’t want false negatives, but if they do happen, you’re missing things you’d already miss anyway — because there’s no way people would trial down all those pics by hand.

It also skips a few issues associated with chatbots and image generators, like:

  • since it’s “trained” for a specific purpose, it isn’t DDoSing sites for training “data”. It’s all from the telescope, AFAIK in the public domain.
  • no massive training = no massive water/energy cost.
  • no concerns related to authorship or whatever.

That’s a composed image though, isn’t it?

Most definitely some kind of exposure.

Simply amazing! Thank you both for the amazing photo and the explanation of everything in it. Sharing this with my kids in the morning!

Also, love that we can see Betelgeuse.

Can we be sure? An ai only knows stuff its trained on?

Headline suggests that this is an observed fact, rather than the result of a simulation based on a model created by several EU scientists.

Furthermore the article asserts that “The observed motions … can only be properly explained with this “flat” mass distribution.” That premature assertion, based on this paper

www.nature.com/articles/s41550-025-02770-w

will have to stand up in the court of opinion of scientific peers. I hope to see Sabine go after that headline.

Yeah, I figured. She’s just a bit questionable for my tastes

Well, this is some exciting news.

It blows my mind that they were able to simulate the big bang well enough that running the simulation for a while resulted in stars in the same places as in present reality. That’s crazy.

It’s wild to think that literally every human being who ever lived—all our history, drama, and breakfast plans—is tucked away in that tiny blue sliver disappearing behind the moon. It’s the ultimate "blue marble" moment, but even surge credit card pre approval more lonely.

The good news is we have 50 million years to prepare.

But we’ll still leave it until the last minute.

Nelots, w Phobos: Doomed Moon of Mars

I mean in the grand scheme of things, all moons, planets, and even stars are doomed eventually. For a species with an average life expectancy of 80-some years, there ain’t much of a difference in 50 million and 5 billion years anyway.

guy,

Our moon is escaping us though

Nelots,

True, though as far as I’m aware our sun will destroy Earth and its moon long before it manages to break free.
