    I like this more than the idea of a dark side anyhow - a new moon from Earth just means the far side of the moon is brilliantly lit.

    Hey just apropos of a headline I just saw; there's no dark side of the moon. There's a FAR side. It's illuminated 50% of the time, just like the near side. It's not dark.

    Having now tested all the knuckle injuries (thanks winter) I’ve decided this is the worst one

    An amorphous blob in yellow and orange on a purple background, surrounded by sparkles.
    A similar layout and colors, but more irregular and pixelated; this is data.

    Celebrating with a piece from inktober Olay is donating $1 to for every tweet that uses the hashtag — I figure Art twitter can help this along, post your spacey art with the hashtag

    But there’s lots of information in these maps too, which is why I make them- they can tell me if I suspect the supermassive black hole in the center of the galaxy is brightly growing. Probably not in this case, because I’d expect a central concentration of yellow.

    For me, this map is a prescience phase- some of the quantities of a galaxy that I’m interested in can only be calculated if the light is just coming from stars, so any of the pale yellow regions get tossed out for the next stage.

    The second image is the actual data. It’s a map of a galaxy, where each pixel has a spectrum. The colors are flagging how much I believe that the light coming from pure starlight - pale yellow is prob no, light purple is prob yes! Dark purple is faint light.

    Stage two is "get really good at data presentation". Working on this one.

    I've gotten really good at optimizing my code, in completely related news

    "Huh, this faster, for debugging, mode of my code still takes a few minutes to run, even without going through all the data," I said to myself just now. News Flash, from self to self: the "faster, for debugging, mode" of the code still handles 22 million data points. 🤦‍♀️

    An illustration of a purple peony drips a dark purple liquid from its petals. There is a faint purple glow behind the flower.
