Nördnytt! 🤓Scientists release biggest 2D map of the universe
- anigbrowl - 267 sekunder sedanResearchers expect it will remain the most comprehensive 2D map of our universe for years to come.
Most likely. I doubt there is going to be any serious investment in astronomy over the next decade given economic headwinds and a deteriorating strategic situation. The big money will be going into defense and economic sovereignty and building/launching new high powered telescopes will not be a priority. Optical/sensor advances will be prioritized for earth observation (commercial, military, or weather/climate) and it maybe that we're in an era of diminishing technological returns already. I do expect a lot of analytical advances thanks to the combination of open datasets and AI, although it seems more likely that most of these will be in stamp collecting - interesting astronomical facts for people who are already interested in astronomy. Hard to guess if we will see challenges to prevailing cosmological theories.

- hn_throwaway_99 - 2452 sekunder sedanI 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?
- KaiMagnus - 1605 sekunder sedanI've got some crazy feelings browsing this.
Are there any particularily detailed areas? But maybe the humbling reality is just: The closer we look, the more galaxies appear where we thought was black void…
- doodlebugging - 10637 sekunder sedanThat'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.

- Towaway69 - 9746 sekunder sedanI wonder how many of the red points/stars are black hole stars[1]

- pants2 - 6577 sekunder sedanSeems like some of the most interesting objects are missing or have weird red/green artifacts, why is that?
- br0ceph - 83449 sekunder sedanis there anyway to download the entire map, and play with it locally
- fercircularbuf - 70315 sekunder sedanWow, this is humbling
- therobot24 - 86433 sekunder sedanmake sure you watch the youtube video embedded in the website, it adds some real perspective of just how massive this is
- ionwake - 8284 sekunder sedani note the hyperspace bypass is missing
- cwmoore - 11266 sekunder sedanNot this data, but from nearby 3D star map with rotations:
- TheSpacerr - 5632 sekunder sedanAbsolutely crazy
- Razengan - 7322 sekunder sedanCould this be used for a new Elitelike game?
- antonvs - 7509 sekunder sedanNot many people know this, but the actual universe is 3D, so this map is misleading.

- zuzululu - 9883 sekunder sedanwhy 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
- cryptolobster - 6829 sekunder sedanHoly shit, this is very impressive
- ck2 - 4338 sekunder sedanvaguely 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
