    I read the article but didn't watch the videos yet, but I'm curious as to what would be needed to make this a 3D map. That is, I'm assuming this 2D map records the position of all of these objects in the sky, but not the distance from Earth. But I thought that calculating the distance of objects is relatively straightforward, e.g. you hear all the time "Galaxy X is 2 billion lightyears away" or whatever. Would it just be really computationally expensive to calculate the distance to all of the 4 billion objects identified in the map?

      I think it is 2D because the universe is not that thick?

    I knew the universe was nothing but a brick wall, now we have proof!

    That's impressive. Though I think there's too much space on this plane. I'm wondering whether it is actually a 2D view since it obviously isn't planar.

    To paraphrase Samuel L Jackson - "I have had it with this m'f'ing space on a plane! Everybody strap in I'm about to open some f'in' windows."

    Proceeds to crank open an array of telescopes to get another 3D perspective of a 4D universe so we can project it onto our 2D viewing devices as if that were reality.

    For 2001 fans, Atmosphères by Ligeti[1] also works very well while doom scrolling the endless canvas that is the Universe.

    And here I thought this was the biggest 2D map.

    I wonder how many of the red points/stars are black hole stars[1]

    Seems like some of the most interesting objects are missing or have weird red/green artifacts, why is that?

    is there anyway to download the entire map, and play with it locally

    Wow, this is humbling

      In what ways? Galaxies are just fat fucks, they don't do no philosophy, play piano or shitpost.
      • Towaway69 2 hours ago
        If you squint, look at just the right portion, at just the right zoom level, the stars line up and spell out "thanks for all the fish".
        • sambapa 2 hours ago
          Hm, that's a good thing to consider - are there portions of the sky in which stars align into a coherent text?
          • Towaway69 1 hour ago
            Just gotta join the dots! ;)

            Or better still, develop a traveling salesman solution for visiting each star just once.

            So that wouldn't be just an academic exercise!

            Feed it to an LLM to see what it hallucinates

            I think the odds of a character are very high, the odds of a short word are very high, the odds of a meaningful sentence are quite low, and the odds of anything more than that vanishingly small. It probably also depends on whether you're ok with viewing your assembly from an arbitrary position or if it must be from earth.

    make sure you watch the youtube video embedded in the website, it adds some real perspective of just how massive this is

      Yep and the examples are really cool!

    Not this data, but from nearby 3D star map with rotations:

    Could this be used for a new Elitelike game?

    Not many people know this, but the actual universe is 3D, so this map is misleading.

    Holy shit, this is very impressive

    why is there so many weird flat lines is that an artifact?

    this is fascinating wish there was a 360 VR version of this

    truly immense scale

      back when I was playing with making VR content, this is one of the first things I did by using an 8K rectilinear image from NASA. Mapped it to a sphere and lined up Polaris at the zenith, and then just had one of the best nights of stargazing I had ever had!

    vaguely related to universe maps, I've been holding my breath for the Nancy Grace Roman Space Telescope launch at the end of the month

    It's going to do the best surveys EVER, like exponentially better

    * https://svs.gsfc.nasa.gov/14942/

    I thought for sure DOGE was going to kill it, or even rename it after him instead

    But the smallest planet Roman will be able to see would be Jupiter sized

    There was however going to be another telescope scheduled to launch in 2040 that could find earth-like worlds

    Fittingly enough it is called the "Habitable Worlds Telescope"

    but you know what, DOGE got that one

    Congress allocated $150 Million to begin development this year

    Somehow the executive branch pocketed that and changed it to $5 Million instead despite having no right to do that

    Yet another crime against science by this administration

    Hoping new Congress in January 2027 can fix this but I doubt it as too much of the rest of the country is "on fire" that has to be put out first

    So now won't be able to see its results in my lifetime
