Interplanetary path screen
Choose spatial endpoints and a time direction. Backward mode is reverse playback of a forward-time modeled orbit; it does not solve continuous traveler motion toward a decreasing environment epoch.
Forward routes use a zero-revolution Lambert transfer and integrate under modeled gravity, then screen planets, covered moons, curated small bodies, available recorded spacecraft, and sampled satellite TLEs. Backward mode swaps endpoints, solves an ordinary forward-time arc, and reverses its playback. It does not integrate a forward-experiencing traveler whose environment epoch decreases continuously. Collision results apply only to the synthetic spatial arc and covered object records. Coverage gaps, unmodeled objects, and orbit uncertainty remain; no result certifies a time-travel route.
Probe trajectory · space to surface
Choose an archived probe path. Phoenix cruise is replayed in heliocentric space; Phoenix entry, descent, and landing and MRO Jezero are replayed around Mars with terrain when coverage is available.

Stick mapping
The stick steers the camera smoothly; let go to stop. The compass follows the camera. The throttle sets journey time scale continuously from 1× to 10× without jumping the timeline. Moving the stick switches from full-sky dome to the projector-aimed window view. The dashboard readouts refresh live while this tab is open.

If your child stirs, the room glows back up softly with the nocturne playing, then fades to black once they settle.

UFO journeys
Treat each report as a destination constraint. Visit the estimated craft position at the event epoch, or replay the sky from the witness location. A preview sets the scene; a continuous past-directed route is not yet solved.
Stellar & planetary maps
Browser image viewer: observations stream from Astrarium and render in this tab; projector connection is optional. Drag to pan · scroll or pinch to zoom. Previously viewed image data remains available offline on this device.
Quasars are plotted as a density layer. Hover or tap a marker for its SDSS designation, redshift, and estimated comoving distance. Distance is inferred from redshift using a flat ΛCDM model (H₀=70 km/s/Mpc, Ωₘ=0.3), not directly measured. Catalog: SDSS DR16Q.

Deep-sky image studio
Render the sky from Gaia stars and 3D gas, or show a real telescope observation. Telescope-only mode uses calibrated, sky-aligned MAST science pixels, including the stars and nebula as observed. Drag the image to travel across the field; scroll or pinch to zoom. Copy image link shares the current pointing.
Astrarium catalog reconstruction
H II surface mesh: Gaia Sky Gaia DR3 dataset by Kevin Jardine, based on known ionizing stars and clusters, H-alpha survey sizes, and Gaia distance estimates. This is a projected 3D isodensity surface, not telescope pixel data. Dataset details · Creator notes.
Black holes
Confirmed black-hole systems plotted at their measured sky positions. Stellar-mass systems are shown at the visible companion’s catalog position; masses and distances are approximate published values.

The selected star follows a smooth Milky Way disk, bulge, and dark-halo gravity model; its planets and the ship stay in local gravity-bound orbits. Measured proper motions and radial velocity seed the galactic path when available. If stellar motion is missing, Astrarium assumes a circular disk orbit; this is a test-particle model, not a star-by-star N-body calculation. Missing masses are estimated. Surface colors and phase are illustrative where unknown. Data: NASA Exoplanet Archive, confirmed Planetary Systems table.

Night sky viewer
Point your phone at the sky to identify stars and guide toward named stars or black holes. Location and motion sensors are used only on this device.
Viewer stopped · start to request location and phone orientation.
Heading uses the phone compass and can be affected by nearby metal or electronics. Black holes are not visible directly; their positions are marked from the catalog. Tilt your phone in a figure eight to calibrate its compass if the direction seems inaccurate.
Stellar cartography
For a steadier solve, prop the phone securely on a surface facing up, with an unobstructed view of the sky. Keep it still while the app combines a short burst of frames, then matches persistent points against bright stars predicted from your location, time, and phone orientation.
Camera off · location and orientation not requested.
Use HTTPS and allow camera, location, and motion access.
Use a stable, level surface away from metal. The burst suppresses changing noise but cannot recover detail the camera sensor never captured; clouds, city glow, focus, and exposure still matter. GPS provides surface position; matching stars refines pointing, not GPS accuracy.
