When to use Earthshine 3D Explorer
Use this explorer when you want to understand the ashen glow on a crescent Moon, and skip it when you want the full cycle of lunar phases or the day-night map of Earth.
- Explaining the old Moon in the new Moon arms
- Tracing light from the Sun to Earth to the Moon and back
- Linking Earth albedo to how bright the glow looks
This is an educational visualization with boosted glow, not to scale.
Walk the controls in the step-by-step guide, or compare options in vs alternatives. Open the Earthshine 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.
- 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.
