ED Astrometrics: Maps and Visualizations

I finally got around to adding a section for exobiology on the exploration tips page:

https://edastro.com/exploration/#exobio

Also added a spreadsheet of the top closest binary star orbits. There's not much variation here, so I might lengthen the list later, or change the metric. But for now it's looking at the "average" orbital separation by adding the two SemiMajor Axes. So this is a distance between their centers, not their surfaces. I might consider making a second list based on the surface distances (subtracting their radii).

This is very much still a work in progress, and can break at any moment while I'm working on it. But I think it's far enough along to show it off a little bit.

I'm working on a real-time map of EDDN exploration activity. Opening it up in the web browser does an initial pull of the last half hour's worth of EDDN events, and maps them. As long as you leave it open in the browser, it will auto-update, downloading the deltas and redrawing the map dynamically (including if you change the pixel scale slider, or if you resize the window).

Activity spots on the map are colorized so that brighter is more recent, and the locations fade as they age away. This allows you to see some nice streaks on the map where someone is traveling at a fast pace.

A fun little "easter egg" that might be appreciated here-- the background nebula image on the page is the real-world NGC 7822. Because it's always NGC 7822. ;)

EDIT: The EDDN events are managed server-side, and what the client sees is a subset of events, limited to jumps and scans, and only looks at the coordinates. This keeps the data footprint small, and only the server needs to be subscribed to the EDDN feed.

Probably not, with the way I have this set up, but I'll put some thought into how that might be doable. So, I'll say "maybe". ;) Right now I have it designed to be as fast and lightweight as possible.
