Exoplanet Atmosphere Spectroscopy 3D Explorer vs alternatives
The Exoplanet Atmosphere Spectroscopy 3D Explorer shows the molecule-by-molecule transit signal in the browser - JWST data archives win for the exact published spectra; astronomy textbooks win for the full radiative-transfer derivation.
| Option | Strength | Access | Trade-off |
|---|---|---|---|
| Exoplanet Atmosphere Spectroscopy 3D Explorer (this page) | Real WASP-39b band positions, transit-linked spectrum, 4-molecule toggle | Free, in browser | Teaching approximation; not raw JWST data or a retrieval pipeline |
| JWST Early Release Science papers (Nature, 2023) | Exact published spectra and statistical detections | Free, published reference | No interactive 3D scene |
| Astronomy textbooks | Full radiative-transfer and retrieval derivation | Free/paid, education-focused | No 3D teaching scene |
Key published figures
| Figure | Value |
|---|---|
| Target studied | WASP-39b, a "hot Saturn" about 700 light-years away |
| Orbital period | 4.055 days |
| Transit depth | about 2.1% |
| Carbon dioxide (CO2) band | about 4.3 micrometers - first definitive exoplanet detection, JWST 2022 |

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.
- Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
