When to use Kilonova 3D Explorer
freetoolonline.com editorial team
Use this explorer when you want to see the real event that was detected in both gravitational waves and light, and why that combination mattered.
The numbers side by side
| Aspect | Kilonova 3D Explorer | Typical alternative |
|---|---|---|
| Install size | 0 MB - runs in the browser | Desktop astronomy software varies |
| Price | USD 0 | Often paid software |
| GW170817 gamma delay | 1.74 seconds after merger signal | News article without event scrub |
- Showing the real 1.74-second gamma-ray delay that tightened the gravity-speed-equals-light-speed constraint
- Explaining where heavy elements like gold and platinum actually come from
- Contrasting a neutron-star merger's real light show with a black-hole merger's total darkness
This is an educational visualization with a schematic inspiral and an illustrative gamma-ray jet angle - the real jet was not pointed at Earth for this event.
Walk the controls in the step-by-step guide, or compare options in vs alternatives. Open the Kilonova 3D Explorer.
Why trust these tools
- Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
- No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
- Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
- Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
