Holographic Cosmos — start at today's real Solar System and travel out to galaxies and the Local Group
A 3D universe map that works with no internet
From Mercury to Neptune, everything starts at its real position for today's date and moves in real time at its real orbital and rotation periods (sidereal days). Earth's day/night line and the Moon's phase match today too. Speeds run from 2X to 128X with pause, and satellites or telescopes you've switched off keep moving at their real periods while hidden.
True distance and size ratios, Lagrange points (L1–L5) and Trojan regions. Every planet gets the hologram grid and day/night shading toward the real Sun.
The International Space Station, the Starlink swarm, the James Webb Space Telescope on its Sun–Earth L2 halo orbit (about 3.9× farther than the Moon), and the Starbase launch site in Texas with a Starship model.
From the LMC, SMC, Andromeda and Triangulum to dwarf galaxies, at their real directions, distances and shapes.
Proxima Centauri, TRAPPIST-1, Sirius and other nearby stars appear in their real directions; 10 constellations plus nebulae and clusters use real coordinates.
Browse 12 categories — clusters, nebulae, galaxies, star systems, planets, moons, satellites, space stations, telescopes and more — or search by name and jump straight there.
22 galaxies around the Milky Way, with trail lines showing their real motion.

This app is for education and visualization. Sizes, distances and positions of celestial objects are approximations for learning and cannot be used for navigation or observation planning. Models of facilities near Earth are simplified and drawn oversized so they are visible. One fictional station is included and clearly marked as fictional.
