I built an interactive 3D map of every known neutron star

The site aggregates data from ATNF, McGill, SIMBAD and a few other sources into a single place you can actually navigate and explore. About 4,100 objects total, updated weekly.

https://viserac.github.io/neutron-star-project/

What it has right now:

3D visualizer with filters by type, galaxy, and distance. Click any object to see its coordinates, period, period derivative, distance, and links to Wikipedia and SIMBAD.

P-Pdot diagram with magnetic field isolines, characteristic age isolines, and the pulsar death line. Hover to identify any object.

Galactic heatmap with scatter, hexbin and KDE modes, overlaid on a calibrated GLIMPSE infrared image.

Full catalog table with 48 columns from ATNF and McGill, sortable, filterable with regex, and exportable as JSON or CSV.

A REST API for anyone who wants to query the data programmatically without downloading anything:

https://neutron-star-api.mistyck.workers.dev/

You can do things like:

import requests

results = requests.get("https://neutron-star-api.mistyck.workers.dev/cone?ra=83.8&dec=22.0&radius=2.0").json(.json())

The whole thing runs in the browser, no install needed. The pipeline and site are open source:

Happy to hear feedback, especially from people who work with pulsar or magnetar data. There are still several analyses I want to add including nearest neighbor search, clustering, and a line of sight tool.
