Explore a supernova remnant - an expanding shock shell like the Crab Nebula. Scrub age after the explosion, play/pause expansion, and toggle filaments around the neutron-star core.
Published teaching figures (Crab case): distance ~6,500 ly, expansion ~1,500 km/s, historical SN 1054. Star Lifecycle 3D teaches the timeline; Neutron Star Pulsar 3D teaches beams - this page teaches the remnant shell.
Drag to orbit and scroll or pinch to zoom. Scrub age, play/pause, or toggle filaments.
Supernova Remnant 3D Explorer
This browser explorer shows a supernova remnant as a teaching schematic - not a hydrodynamics solver. Using the Crab Nebula as the literacy case: about 6,500 ly away, expanding near 1,500 km/s, born from the SN 1054 guest star, with a neutron-star core.
Scrub age after the explosion to grow the shell, play/pause expansion, or hide filaments for a clearer wireframe view. Star Lifecycle 3D owns evolutionary stages; Neutron Star Pulsar 3D owns pulsed beams - this page owns the expanding remnant shell.
- Expanding orange remnant shell with filament particles
- Bright neutron-star core marker
- Age scrubber (years after explosion) with play/pause
- Filament visibility toggle
- Published ~6,500 ly / ~1,500 km/s / SN 1054 teaching figures
- Distinct from star-lifecycle and neutron-star-pulsar
- Runs fully in the browser with the vendored three.js engine - no account, no upload
Students see how a shell grows with age; teachers link expansion speed to remnant size; curious readers connect the 1054 guest star to today's Crab Nebula.
| Figure | Value | Source note |
|---|---|---|
| Distance | ~6,500 ly | Crab Nebula literacy |
| Expansion speed | ~1,500 km/s | Shock / filament order of magnitude |
| Historical SN | 1054 CE | Guest-star records |
| Core remnant | neutron star | Pulsar beams on sibling page |
Everything renders on your device with WebGL. The 3D engine loads once (about 0.7 MB) and is cached; no scene data is sent to a server.
This is an educational remnant schematic - not a hydrodynamics or MHD model.

Frequently Asked Questions
What does the Supernova Remnant 3D Explorer show?
A teaching schematic of an expanding remnant shell like the Crab Nebula - about 6,500 ly away, expanding near 1,500 km/s after SN 1054 - with a neutron-star core marker.
What is SN 1054?
A bright guest star recorded in 1054 CE. Its debris is the Crab Nebula we observe today, still expanding at about 1,500 km/s.
How is this different from Star Lifecycle 3D?
Star Lifecycle 3D teaches evolutionary stages along a timeline. This page teaches the post-explosion expanding shell and remnant geometry.
How is this different from Neutron Star Pulsar 3D?
Neutron Star Pulsar 3D teaches pulsed beams and spin. This page teaches the surrounding remnant shell that expands around that core.
Why scrub age?
Age after the explosion grows the schematic shell radius so you can see how a young remnant differs from a ~1,000-year-old Crab-like case.
Is this a hydrodynamics model?
No. It is an educational remnant schematic - not a hydrodynamics or MHD solver.
