Touching the Sun
Despite its familiarity, the Sun is a very different presence from the friendly yellow circle in children's paintings. Our star is a broiling mass of plasma, with its powerful magnetic fields, twisted...

Disturbingly suggests that Button Moon is our own world, which has all sorts of problematic implications.

I think it would be a shame to declare that astrophysics can only be done within the professional field. What about retired colleagues or those who have moved on? Citizen scientists? Amateur observers? Experts from other fields? One could validate people, but that doesn't work well for arXiv.

From what I can tell, most of them think that they have the capacity to make a contribution (with LLMs). I thought Hogg's distinction about 'wanting the result' and 'wanting to do astrophysics' very useful in thinking about this.

There are a large number of people outside the professional academic system who want to write papers with LLMs. (Perhaps a separate problem, but still part of it, and it shows it's not all about advancement within the field)

Ah, but how? One obvious answer (which gets at what Hogg has to say about trust) is that it goes back to being a closed shop, reversing progress in open science.

I'm reminded of the old saw about wanting AI to take care of the admin and the washing up, while we do the science and art, but getting the opposite. I want ML tools for better review, but instead we're spending human effort on reviewing ML output.

Astronomers: highly recommend this thoughtful opinion piece by @hogg.bsky.social on how to think about our field in light of the development of large language models. whether you agree with him or not itβs vital to discuss the principles behind our science. π arxiv.org/abs/2602.10181
Why do we do astrophysics?
At time of writing, large language models (LLMs) are beginning to obtain the ability to design, execute, write up, and referee scientific projects on the data-science side of astrophysics. What implic...

Just a note to say this post just proved genuinely useful, and may have prevented my annual winter sadness about my bike lock.

As Emily says, we need to probe Uranus to find out whatβs inside.

They were wrong about whatβs inside Uranus
(Jokes aside, there have been a bajillion modeling papers about the internal structure of Uranus and Neptune and none of them will be provably right or wrong until we get a damn orbiter to one of them)
