The Sun
A dynamic sphere of plasma photographed by NASA's SDO every 12 seconds in 12 wavelengths, from the 5,000 K surface to 10 MK flare plasma. Each wavelength reveals a hidden layer of solar activity. See the 12 wavelengths explained.
☾
The Moon
Completing a cycle every 29.53 days. Lumara uses the lunar series from Jean Meeus's Astronomical Algorithms to calculate phase, illumination, rise and set, and distance offline. See the moon phase tonight, or plan ahead with the 2026 full moon calendar.
⚡
Space Weather
Solar flares rated B to C to M to X. Coronal mass ejections at up to 3,000 km/s. Geomagnetic storms on the G1 to G5 scale that drive the aurora and northern lights. Lumara tracks all three live from NASA's DONKI database. See the space weather guide, check today's solar flares, or whether the northern lights are out tonight.

Your location stays on your device. Solar and lunar images are fetched directly from NASA servers, so we never see your data. The app collects nothing at all.
Two things on this website are worth naming plainly. To see which pages get read, each page load pings a counter we run ourselves, recording only the page path and the day: no cookies, no IP address, no browser details, no identifier of any kind, so nothing links a view to a person. And the typefaces are served by Google Fonts, so Google receives your IP address and browser on each visit. The ISS video contacts YouTube only after you press the button that loads it, never before.
