Currently **297** SNRs. ## Dataset description Supernova remnants (SNRs) are the expanding shells of gas and dust left behind after a supernova explosion. They are key sources of cosmic rays and play a major role in the chemical enrichment of the interstellar medium. Green's catalog is the standard reference for Galactic SNRs, maintained since 1984. This dataset includes positions (equatorial and Galactic), angular sizes, morphological type, 1 GHz radio flux density, and radio spectral index for each remnant. ## Schema | Column | Type | Description | |--------|------|-------------| | `name` | string | SNR designation (Galactic coordinates, e.g. "G001.0-00.1") | | `alt_names` | string | Alternative/common names (e.g. "Cas A", "Crab Nebula") | | `ra` | float | Right ascension (degrees) | | `dec` | float | Declination (degrees) | | `lii` | float | Galactic longitude (degrees) | | `bii` | float | Galactic latitude (degrees) | | `major_diameter` | float | Angular size major axis (arcmin) | | `minor_diameter` | float | Angular size minor axis (arcmin) | | `type` | string | Morphological type code (S, F, C, ?) | | `flux_1_ghz` | float | Radio flux density at 1 GHz (Jy) | | `spectral_index` | float | Radio spectral index | | `snr_type_name` | string | Full type name: shell, filled-centre, composite, uncertain | ## Quick stats - **297** supernova remnants - **234** shell, **9** filled-centre, **37** composite ## Usage ```python from datasets import load_dataset ds = load_dataset("juliensimon/supernova-remnants", split="train") df = ds.to_pandas() # SNRs by type print(df["snr_type_name"].value_counts()) # Brightest SNRs at 1 GHz top = df.nlargest(10, "flux_1_ghz")[["name", "alt_names", "flux_1_ghz"]] # Sky distribution in Galactic coordinates import matplotlib.pyplot as plt plt.scatter(df["lii"], df["bii"], s=5) plt.xlabel("Galactic longitude (deg)") plt.ylabel("Galactic latitude (deg)") plt.title("Galactic SNR Distribution") ``` ## Data source All data comes from [Green's SNR Catalog](https://www.mrao.cam.ac.uk/surveys/snrs/) hosted by NASA's High Energy Astrophysics Science Archive Research Center (HEASARC), accessed via the TAP protocol. ## Update schedule Quarterly (1st Monday of January, April, July, October at 19:00 UTC) via [GitHub Actions](https://github.com/juliensimon/space-datasets). ## Related datasets - [gamma-ray-bursts](https://huggingface.co/datasets/juliensimon/gamma-ray-bursts) — Fermi GBM GRB Catalog - [gravitational-waves](https://huggingface.co/datasets/juliensimon/gravitational-waves) — LIGO/Virgo detections - [exoplanets](https://huggingface.co/datasets/juliensimon/exoplanets) — NASA Exoplanet Archive ## Pipeline Source code: [juliensimon/space-datasets](https://github.com/juliensimon/space-datasets) ## Citation ```bibtex @dataset{supernova_remnants, author = {Simon, Julien}, title = {Green's Supernova Remnant Catalog}, year = {2026}, publisher = {Hugging Face}, url = {https://huggingface.co/datasets/juliensimon/supernova-remnants}, note = {Based on Green's SNR Catalog via NASA HEASARC} } ``` ## License [CC-BY-4.0](https://creativecommons.org/licenses/by/4.0/)
