The universe,
observed openly.
Open Void streams real-time data from a distributed network of ground and orbital observatories — giving researchers, educators and enthusiasts open access to the deep sky.
Everything above the horizon
A unified toolkit for capturing, tracking and understanding what moves through the night sky.
Orbital tracking
Follow satellites, debris and near-Earth objects with sub-second telemetry and predictive pass modelling.
Remote telescopes
Queue exposures on our shared instrument network and pull calibrated frames straight to your workspace.
Deep-sky imaging
Stack, align and process wide-field captures with GPU pipelines tuned for faint nebulae and galaxies.
Signal archive
Query decades of radio and optical observations through a single, versioned scientific API.
Sky navigation
Plate-solve any frame in milliseconds and get precise equatorial coordinates for every field.
Alert streams
Subscribe to transient events — supernovae, flares and occultations — the moment they are detected.
Open data for the whole sky
We believe astronomical data should be a shared resource. Open Void connects independent observatories into one federated network and publishes the results for anyone to use.
- ✦ Free tier for students and educators, forever.
- ✦ Open formats — FITS, VOTable and JSON out of the box.
- ✦ Reproducible pipelines with full provenance tracking.
- ✦ Community-reviewed catalogues updated nightly.
Built on an open scientific API
Access every observation programmatically. Authenticate once and stream calibrated data anywhere.
Reproducible
Every dataset ships with the exact pipeline version and calibration frames used to produce it.
Secure by default
Token-scoped access, end-to-end encryption and audited data lineage across the network.
Global mirrors
Edge-cached archives on five continents keep queries fast wherever you observe from.
