UniverseDaily – Sun & Planets

UniverseDaily is a daily-curated astronomy app powered by NASA, ESA, and astronomy-engine. Real telescope and observatory data, organized into four tabs.

* Today
A live 72-hour Sun timelapse from NASA's Solar Dynamics Observatory plays on launch (Wi-Fi · cold start). 19 SDO channels — coronal loops, solar flares, magnetic fields, sunspots. Plus NASA APOD and a daily Moon card with phase, illumination, lunar age, next full moon, and the Korean lunar calendar.

* Sky — Tonight's observation
NEW Sky View: point your phone at the sky and see the Sun, Moon, planets, 1,665 stars and 89 constellations right where they really are — with AR camera background, red night mode, and time scrubbing. When the Moon meets a planet, a Tonight card and an optional evening alert let you know, and an arrow guide leads you to the target.
Plus sunrise · sunset · twilight times, Moon phase, planet visibility with rise/set for your location, the next solar/lunar eclipse, annual meteor showers, and an aurora forecast (NOAA Kp).

* Explore — From the Solar System to the cosmic web
Interactive 3D viewers for 7 planets (Mercury · Venus · Mars · Jupiter · Saturn with rings · Uranus · Neptune). Each planet card lists its moons with relative size and distance. Earth in DSCOVR EPIC full-bleed with 48h timelapse, a 3D Terrain mode (ETOPO 2022 seafloor relief) with surface landmarks, and a 7-step Birth of the Earth story. Sun with 19 SDO channels and 72h timelapse. Moon in 3D from NASA LRO data. 3D comparison console — Orbit, Gallery, and Travel views with auto-tour, light-speed playback, and a time slider.
NEW: journey beyond the Solar System through six cosmic scales — stars, star clusters, stellar remnants, interstellar matter, galaxies, and large-scale structure. An encyclopedia of 70+ real objects (Sirius, the Pleiades, the Crab Nebula, Andromeda and more) with photos, facts, and Wikipedia links. 20+ interactive 3D scenes: the H-R diagram, the life of stars, galaxy collisions, supernovae, a kilonova, and more. Cross-cutting threads — the origin of the elements, the speed of light, the four forces — connect it all.
NEW: cutaway interiors of 16 bodies — peel back the layers of the Sun, Earth, Jupiter and more, down to magnetic fields, pressure, and density.

* Gallery
Daily picks from Hubble Space Telescope, James Webb (JWST), the European Southern Observatory (ESO), and Mars rovers Curiosity & Perseverance.

* Widgets & alerts
A home-screen widget rotating today's pictures from APOD, Hubble, JWST, and ESO. Optional notifications when a new Picture of the Day arrives — and when tonight's sky is worth a look.
