  • As they swing past one another (within the central white dot in the Webb images), the stellar winds from each star slam together, the material compresses, and carbon-rich dust forms. Webb’s latest observations show 17 dust shells shining in mid-infrared light that are expanding at regular intervals into the surrounding space.

    […]

    Like clockwork, the stars’ winds generate dust for several months every eight years, as the pair make their closest approach during a wide, elongated orbit.

    reference: https://science.nasa.gov/missions/webb/webb-watches-carbon-rich-dust-shells-form-expand-in-star-system/

    Baaically you’re looking at dust showing a pattern of stellar turbulence. There’s a nice video clip in the article that shows how the two stars orbit each other. Because the orbit is consistent, it is producing these compression waves every 8 years when the stars are closest to each other.

    Also interesting:

    The dust’s distribution isn’t uniform. Though this isn’t obvious at first glance, zooming in on the shells in Webb’s images reveals that some of the dust has “piled up,” forming amorphous, delicate clouds that are as large as our entire solar system.


  • If you’re posting relevant, quality & especially original content then it’s not spam. If you crosspost it to a bunch of communities on the same server that’s a little spammy, so maybe don’t do that, but I don’t think it’s spammy to crosspost to similar communities on other servers.

    Also consider defining the scope of your new community differently. It might be the same topic as another community, but is it more focused? more nuanced? what’s the niche you want to fill that the larger community doesn’t, or doesn’t dive deeply enough into?

    And finally manage your expectations. You might have to be the sole contributor for a year or more before you start seeing active participation from other users.










  • Hmm…

    The ketogenic diet is not considered a benign, holistic, or all-natural treatment. As with any serious medical therapy, it may result in complications, although these are generally less severe and less frequent than with anticonvulsant medication or surgery. […] Supplements are necessary to counter the dietary deficiency of many micronutrients. […] Like many anticonvulsant drugs, the ketogenic diet has an adverse effect on bone health. […] In adolescents and adults, common side effects reported include weight loss, constipation, dyslipidemia, and in women, dysmenorrhea.

    Sounds like you’re right, this diet is something that should be done for specific medical reasons, with professional guidance and with specific goals in mind:

    The ketogenic diet is a high-fat, adequate-protein, low-carbohydrate dietary therapy that in conventional medicine is used mainly to treat hard-to-control (refractory) epilepsy in children.

  • anyone who calls you a Russian propagandist

    This is in fact a propaganda piece. It presents no information, only opinions. It makes only vague accusations, not specific examples of the “lies” which could be discussed or disproven.

    Claims made without evidence can be dismissed without evidence.

    it’s mighty convenient how Russia being tied up in Ukraine

    This sentence implies that “the western empire” is somehow to blame for Russia not getting to invade and conquer a neighbor quickly and easily, and that that’s a bad thing.

    If Russia finds “being tied up in Ukraine” inconvenient, I can think of one way they could resolve that… go the fuck home.


    Yes, ask questions, be skeptical, don’t take the official story at face value… but don’t accept answers to those questions from Putin sympathizers.

    I second this - virtualization is the easiest way to branch out and try new things. You can keep the working system you already have, and also experiment with other systems.

    A further advantage is that you can run services in separate VMs, which helps if you need isolated contexts for security, privacy, or stability reasons. And, if you break something while you’re learning you can just delete that VM and start over without affecting your other working services.
