Pretty narrow, only a few degrees across, therefor: tan(theta)*(distance to supernova) = diameter
So, assuming 8,000 LY we get: tan (2 degrees) = 0.017 * 8000LY = 136 LY across.
Basically enough to fry us and a few hundred other star systems at the same time
I pulled the beam with info from this conversation.
You can simulate this in your computer. You can download Celestia, an astronomy software that lets you travel between the stars and explore the Milky Way in 3D space. You can star-hop around and see that, within the Solar System, even within the Local group, most of the constellations remain largely intact. It's when you travel to distant stars that the constellations are distorted, because they're Solar-centric.
The sine wave is the disk of the Milky Way; it appears as a circle (distorted into a sine) because we're inside of it, looking outwards. You can actually see three other galaxies in the picture; the Magellanic Clouds, small galaxies that orbit the Milky Way, are the two spots near the bottom under the highest part of the sine wave, and the Andromeda Galaxy is barely visible close under the peak (here). The Milky Way is just much more prominent in the picture than they are, because the Magellanic Clouds are much smaller than our galaxy and the Andromeda Galaxy (which is the same size as the Milky Way, roughly) is rather far away.
I'd recommend taking a look at Celestia, a free program that renders the universe in 3D. If you look around from Earth, you can see the sky as it appears in Google Sky, but you can also zoom out to see the galaxy from the outside. The demo (under the help menu) is also pretty cool.
If by "3D map or chart", you mean just view the cluster in 3D, then either Celestia or Space Engine would work. They are 3D simulations on the known universe and beyond so you just have to search for that cluster in either of them.

Inteiro ainda não dá, mas com os softwares acima, dá pra passear um bocado através do universo observável. E num piscar de olhos, não precisa ter vida infinita.☺
> I'm looking for constructive criticism
Why would I use this instead of Celestia or Space Engine, both of which can load user data sets and move forward and backwards in time?
Seriously, not a personal attack. Just don't understand why you would re-create the wheel when there are already programs out there that do it better and faster?
Of course, the amount of radiation Earth would receive from two stars would depend of the distance of the two stars are from Earth. Earth would receive twice the radiation only if the two stars where the same size and the same distance from Earth. This is very unlikely. So I think you need to do a number of scenarios with Suns at different distances.
Here are some resources and online calculators which might help you do that.
If you're especially interested in creating your own solar/ star systems or traveling only through the existing solar system/ universe you shoud check the below named websites. You probably won't believe what you could easily create and/ or explore. - It is 100% free, real-time, 3D, detailed as far your computer can go and you can time warp to the future or the past. Moreover you can travel to any destination at your desired speed or even instantaneous jump to any place in the universe. - But it is no rocket simulation! The celestia space website says: "Celestia - real-time 3D visualization of space. The free space simulation that lets you explore our universe in three dimensions." - By the way, NASA, ESA and other space agencies are using it for their presentations of spacecraft travels. - And no, I'm not related in any way to that project. I only used it for more than 10 years and found it very helpful for explanations of space stuff to friends and children. https://celestia.space/ http://www.celestiamotherlode.net/
Worshiping planets and trying to get their alignment to predict the future is a sin.
Studying them is the science of Astronomy, nothing wrong with that.
Check out Celestia and Stellarium.
That's very compelling new information. We'd need to see that math running in a space simulator like this one...
Let's see if you plug those dynamics into an existing earth-space simulator, what happens. I'll bet the Russians are WAY AHEAD of everyone else on this science. They have the most to lose if it's true, all to gain (because they own the pole), and they are the ones that discovered it!
BTW, kudos to the Russians! They discovered this by pure human experimentation in orbit. Those cosmonauts aren't just courageous, they are clever in zero-g!
Technically speaking, it's a very easy simulation, and holding on to it would be even easier. Considering how good science is in the Expanse, that would've been a piece of cake for them. All it requires is the initial positions of all the relevant objects that they'd need (or use), and just simulate positions for 400 years.
I forgot an application i used more then a decade ago, it was literary similar to Google Earth and Nasa's Globe one, for the whole solar system, you could input the time, and it would show the correct positions of objects in the solar system.
I'm not sure if you can do it with Stellarium, but i think it's doable.
EDIT: found it, Celestia
Alpha Centauri is part of Centaurus :)
The four main stars of the southern cross are quite far away (80-330 ly), so from Alpha Centauri (4 ly) the constellation would look more or less the same.
Also, Celestia can show you the night sky as seen from other stars.
You can try Celestia. It's free and not terribly resource intensive. There's also Space Engine. It's free as well, but a bit harder on your computer. I haven't used Space Engine much myself, but with Celestia at least, all you need to do is put yourself close to Earth, hit enter, type in the name of the object you want to get the distance for, and hit enter again. A data block should pop up, showing the distance, among other things.
Stellarium é como um planetário digital, dá para colocar sua localização e ver o a posição dos planetas, estrelas, satélites e etc em "tempo real".
Celestia simulador espacial 3D.
Ambos são gratuitos e open source.
>The only way to see a scale model of the solar system, is to build one.
Or they could have just used <a rel="nofollow" href="https://youtu.be/Kj4524AAZdE?t=1m">Celestia</a>.
While primarily the earth's rotation, stars can also move themselves.
> So we’ve covered ways the stars “move” due to the Earth’s orbit. But stars can move for other reasons as well. Maybe we’re observing a binary system where two stars are orbiting around each other. Maybe the stars are embedded in a galaxy that is itself rotating. Maybe the star is moving due to the expansion of the Universe, which gradually stretches distances between objects. - Universe Today.
Some fun astronomy apps for OP:
Further than the solar system but less than outside of the galaxy. Probably a handful of light years at most should change the relative position of the stars enough.
You can use this program to view the stars from different positions in the galaxy if that helps.
From ten lightyears away, most of the constellations would probably be pretty similar. I remember seeing sci-fi art that have had some recognizable constellation in the sky of another star, with our own sun added to it, because of the angle.
There's a program, Celestia, where you can view the galaxy from different perspectives and different times, so you can play with it and see how far in space and time you can get and still recognize the sky. https://celestia.space/index.html
Space Engine and good old Celestia let you travel through space and observe the stars from anywhere in the universe. Is this what you're looking for?
Haven't tried any yet but this looks like what you're after.
Personally I'm really hoping someone ports Celestria to Quest. It's open source so I don't see any reason it couldn't happen.
Are you familiar with map projections? The earth is approximately a sphere, and so when you try to make a map, you have to pick how to display it. E.g. https://en.wikipedia.org/wiki/Robinson_projection
Well, an accurate map of the observable universe is also a sphere. Except you're inside the sphere looking out at it. That ellipse you see online is a lot like a map projection.
Anyway, I Google'd "3d visualization of universe" and the first result was https://celestia.space/. Looks cool.
Hope this helped.
Here's v1 of my experiment with making a map for the Expanse. I haven't found many resources that visualize the relative positions of locations in the story. I used Celestia for rendering the orbits. I chose September 2350 to determine the orbital positions, except Tycho Station. The position of Tycho is based on this screenshot.
I found some screenshots from an old SyFy interactive map but I couldn't find the actual interactive map. It also didn't appear to be to scale.
I would be interested if people have information that would help with choosing a more accurate arrangement. There's a lot of constrains from story events. For example, when >!The Roci saves Bobby and Avasarala that constrains the relative positions of Tycho station, Earth, and Jupiter!<
Download Celestia and under Render-> View Options turn on Constellations Diagrams and Labels. Then travel to another location. As long as you're within a few light years of earth, everything looks pretty familiar. Go to a distant (but still bright in the Earth's sky) star like Rigel or Deneb and nothing is recognizable.
Although Astrology seems rediculous I am interested in the effects of planets on the sun and its barycentre.
https://celestia.space/forum/viewtopic.php?f=2&t=11956&p=99478&hilit=barycentre#p99478
Turns out according to them, the planets with the most effect on the sun gravitationally are; 1 Jupiter, 2 Saturn and 3 Venus.
So a conjunction of Saturn and Jupiter must be substantial effects on the Suns wobble around the barycentre. Internal structures in the sun will be influenced by this tidal pull, like the moon has on the Oceans.
If anyone is willing to delve into it these JPL HORIZONS ephemerides can be used to visualize spacecraft path right within Celestia which has its own set of advantages but won't be suitable for a simple and online accessible visualizations like OP offers.
There is an older software like this called Celestia that runs on any hardware, even computers that are not a fraction as fast as yours. While not as pretty as SpaceEngine and lacking some of its features, it still looks great and is just as fascinating. It's free and open source:
It can be expanded by mods, which add high-res planetary textures, fictional and real spacecraft, etc.
I don't want to discourage you from learning a new skill but I thought as an astronomy teacher you might be interested in some very cool free software. Celestia, a digital planetarium and Space Engine, a known universe "simulation".
GIS = Geographic Information Systems Geo = Earth So, you’re correct that it isn’t the right terminology. However, there are similarities such as both disciplines such as both use image analysis.
But, check out Celestia Software
Google Sky! Surprised your source didn't mention it, it's been around for a decade+. It's got imagery for various planets as well as deep zoom stuff of distant stars and galaxies.
If you want something 3-D, try Celestia (it's free!). There are a lot of other similar programs but that's the one I've tried myself.
Download a free program called Celestia. This is an astronomy program, but it lets you move to anywhere inside the galaxy. So, if the alignment is possible you should be able to orient the camera to it. One note, it will take you a day or so of playing with the program to learn it well. The key for you is to turn on constellation lines. https://www.youtube.com/watch?v=N7yePKJlhgw (Old vid but shows the basics.) https://celestia.space/ (Home Page)
That question was fine from my 4 year old nephew on why was the moon out in the day, so I showed him some YouTube videos and took him on a tour of the solar system with https://celestia.space/.
But you know adults who didn't know this?
Judging from the site SE looks really pretty but the license is kind of terrible. http://spaceengine.org/manual/license
I recommend space explorers supplement with Celestia and Stellarium.
