Your Eyes In Space
youreyesinspace.com — a Space Engine–style universe explorer that
runs in the browser. Fly seamlessly from the Solar System to the edge of the observable universe
(13.8 Gpc); real star/galaxy catalogues plus a deterministic procedural universe.
Vite · TypeScript · Three.js. UI in English, Turkish, German, Spanish and French.
Features
- Solar System — planets, dwarf planets, moons and comets from NASA/JPL Keplerian elements, plus
284,000 asteroids and comets on their real orbits (JPL Small-Body Database);
procedural surface/atmosphere/cloud/ring shaders, eclipse and ring shadows.
- Real surface imagery — Earth (NASA Blue Marble NG + Black Marble night lights), Moon (LRO WAC),
Mars (Viking MDIM 2.1); altitude-based LOD tile streaming straight from NASA servers.
- Humanity's spacecraft — Voyager 1/2, Pioneer 10/11, New Horizons, Parker, ISS, Hubble, JWST (L2),
Perseverance, Curiosity, Juno; current positions and NASA 3D models.
- Stars — 2.8 million real stars (HYG, AT-HYG/Tycho-2, Gaia GCNS) and 6,400 confirmed exoplanets
from the NASA Exoplanet Archive; 2,750 L, T and Y brown dwarfs (UltracoolSheet); 4,700 measured
multiple systems (Tokovinin MSC, USNO ORB6); procedural planetary systems; interstellar flight and a
flyable Milky Way.
- Galaxies — 44,000 real galaxies (Updated Nearby Galaxy Catalog, 2MASS Redshift Survey) and 55
hand-curated ones, plus a procedural cosmic web out to 13.8 Gpc; LOD chain.
- Black holes — Sagittarius A* (with the S2/S38/S55 orbits), M87*, M31*, Centaurus A*, Cygnus X-1,
Gaia BH1, V404 Cygni, A0620-00, LMC X-1/X-3, M33 X-7 and more; real-time screen-space Schwarzschild
ray tracing (null geodesics), accretion disc with Doppler beaming and gravitational redshift, shadow
and Einstein ring.
- Deep-sky landmarks — the Orion, Carina, Tarantula and NGC 604 nebulae; the Pleiades, Omega Centauri
and Mayall II clusters; the Crab, SN 1987A and Cas A remnants; record-holding stars such as Eta Carinae,
R136a1 and WOH G64 — at their real positions in the Milky Way and neighbouring galaxies, all flyable;
plus the survey catalogues: 2,900 open clusters (MWSC), 155 globular clusters (Harris), 775 planetary
nebulae (Strasbourg–ESO), 274 supernova remnants (Green) and 2,000 H II regions (WISE).
- Pulsars — the Crab and Vela pulsars, the first pulsar PSR B1919+21, the first exoplanet host
PSR B1257+12 (with Draugr, Poltergeist and Phobetor), the fastest pulsar J1748-2446ad (716 Hz), the
Hulse–Taylor binary, Geminga, J0437-4715 and the magnetar SGR 1806-20; neutron stars spinning at their
real periods, sweeping beam cones along the magnetic axis that flash when they cross the line of sight;
plus the 4,300 ATNF pulsars with a known distance, binaries with their measured companions.
- Mission planner — pick a departure body and a target in the Solar System and get a route for the
selected simulation time: launch-window scan with a Lambert solver, Hohmann (Earth→Moon), single
gravity-assist transfers, elliptical capture; the Δv budget is compared against real vehicles (Voyager,
New Horizons, Parker, Juno, Galileo, Cassini, Dawn, Orion, Starship). Sci-fi ships (Enterprise-D /
NCC-1701 warp, Millennium Falcon / X-wing hyperspace, Rocinante constant acceleration) can reach stars,
pulsars, black holes and galaxies. On launch the vehicle is added to the scene, the trajectory is drawn
and the camera follows live; on interstellar arrival the reference frame switches to the target system.
- Guided tours — ten narrated lessons (Solar System, Mars and its rovers, Jupiter's moons, Saturn,
spacecraft, the life of stars, black holes, pulsars, neighbouring stars, galaxies). Each stop flies the
camera to the object while a synthetic voice (xAI TTS, voice "altair") explains it; subtitles follow the
per-sentence timestamps, the camera drifts slowly around the target once it has arrived and the next
stop starts only when both the narration and the flight are done. Audio exists for all five languages;
if a locale lacks it, English audio plays with localized subtitles.
- Camera — free flight, orbit, follow, autopilot, pointer-locked roaming; floating origin plus a
logarithmic depth buffer (from 1 m to 10¹³ km).
- UI — search, info panel, time controls, a "Places worth seeing" menu, settings,
F1 help.
- Mobile — touch controls (one finger look/orbit, two fingers zoom/fly and pan, tap / double tap),
phone layout (bottom-sheet panels, safe areas), automatic lower render scale on mobile.
- Multilingual — English, Turkish, German, Spanish, French. UI, info panels, the mission planner and
all body/landmark descriptions are translated; the language is detected from the browser and can be
changed in settings or with a URL parameter such as
?lang=de.
Development
npm ci
npm run dev # http://localhost:5173
npm run typecheck
npm run build # dist/
To rebuild the star catalogue (requires the HYG CSV):
node scripts/build-stars.mjs /path/to/hygdata_v41.csv
Translations: the source language is Turkish; _('…') calls, data-i18n* attributes and the
display fields of the data files are used as keys. Dictionaries live in
src/i18n/locales/<lang>/{ui,data}.json. To find missing/unused keys:
node scripts/i18n-check.mjs # report (exit 1 if anything is missing)
node scripts/i18n-check.mjs --missing de # list missing keys for one language
Guided-tour narration: the scripts live in src/data/tours.ts (Turkish source text); the other
languages are ordinary dictionary entries in locales/<lang>/data.json. The audio under
public/tours/<lang>/<tour>/<step>.mp3 and the manifests with sentence timings are generated with the
xAI TTS API (the key is read from the environment only):
