空を見上げてください。それからこのページに目を落としてください。ここに並ぶ各インストゥルメントは、いままさにあなたの頭上で起きていることの小さなライブ模型です——惑星をめぐって滑る昼夜境界線、実際の軌道を回る八千基の衛星、今日の太陽風に応じてたわむ磁気圏。空を、動く図解として描き出します。
Assemble a multi-stage rocket from engines, tanks and a nose cone, then fly it to the Kármán line — live throttle, pitch and staging against real thrust, gravity and drag.
TLE をリアルタイムに伝播させた3D地球が、まだ一列編隊で飛ぶ最新のスターリンク打ち上げ群——「トレイン」——を見つけ出し、暗くしたコンステレーションの中で点灯させ、地上軌跡と軌道諸元を表示します。
A 3D Earth wrapped in tracked orbital debris from the great fragmentation events — Fengyun-1C, Iridium-33, Cosmos-2251 — propagated live with satellite.js and colored by source event, telling the Kessler-syndrome story shell by shell.
A live view of the Sun straight from NASA’s Solar Dynamics Observatory — switch wavelengths to peel back the corona, the chromosphere and the magnetic field.
A live gallery of raw Mars rover photographs — pick a rover, scrub through the Martian sols and cameras, and watch the surface arrive frame by frame.
A live readout of the wind blowing off the Sun — real-time speed, density, and the interplanetary magnetic field from NOAA, read for storm level and aurora odds as a southward Bz pries the magnetosphere open.
A live board of asteroids skimming past Earth — each plotted by how close it passes and how big it is, straight from NASA’s close-approach feed.
確認済みのすべての系外惑星を探索するライブツール——半径を公転周期に対してプロットし、発見方法ごとに色分け。NASA 系外惑星アーカイブから直接取得。
本物の太陽に照らされたライブの地球です。昼夜境界線は実際の UTC に追従し、夜側では街明かりが灯り、雲が地表の上を流れ、大気の青いハローが縁を包みます。
8,000 基を超える運用中の衛星が、TLE からリアルタイムに伝播した軌道で3D地球を周回します。任意の点をクリックすると名称、NORAD ID、高度、周期がわかります。コンステレーションごとに絞り込めます。
地球の双極子磁力線と磁気圏界面を、NOAA SWPC の太陽風データでライブに形づくります。南向きの Bz は示唆的なリコネクションのアニメーションを引き起こします。双極子近似、Shue 1997 モデルを使用しています。
OpenSky から取得した飛行中のすべての航空機を3D地球儀上のインスタンス化された点として描き、それぞれが約3分ぶんの薄れゆく飛行機雲の軌跡を引きます。軌跡はライブ位置のあいだを推測航法で補間しています。
A 3D fly-through of the Sun’s local stars — the nearest and brightest suns within fifty light-years, coloured by spectral class and ringed by distance shells.
Trace the stick-figures of 36 constellations and read the Greek and world myths behind each pattern of stars.
Watch a planet cross its star and carve the tiny dip in brightness that lets astronomers detect worlds light-years away.
Why the ocean bulges twice — the Moon and Sun stretch the seas by gravity, and their alignment swings the tide between spring and neap.
Pick a star’s birth mass and watch its whole life play out — a marker tracing its track across the HR diagram while the star itself swells, puffs and dies, with the fate (white dwarf, neutron star or black hole) and the wildly mass-dependent lifetime set by real scaling laws.
A smooth logarithmic flight through 62 orders of magnitude — from the Planck length past quarks, DNA, humans, Earth, the Sun, the Milky Way, all the way to the edge of the observable universe.
Thousands of icy ring particles ride Keplerian orbits around Saturn — and the Cassini Division opens exactly where the 2:1 resonance with the moon Mimas clears them, while Pan herds the Encke gap shut.
A clockwork Solar System where all eight planets ride their true ellipses at the correct relative speeds — Mercury sprinting, Neptune crawling — solved live from real Keplerian elements.
A live planetarium: pick a place and a moment, and the brightest stars wheel about the celestial pole with their constellations drawn in.
A physically-lit 3D Moon whose terminator and illuminated fraction are computed from the real Sun–Earth–Moon geometry for any date — scrub time and watch the maria slide under the shifting light.
The year’s great meteor showers, made watchable: streaks rain outward from each shower’s radiant, with peak rates and active windows laid across the calendar.
You never see the universe as it is now — only as it was when the light left; watch a pulse crawl outward at c and feel how deep the past you are looking into.
Three planets trace true ellipses around the Sun while the swept-area and harmonic laws come alive on screen.
The Hertzsprung–Russell diagram drawn live: a whole stellar population scatters into the main sequence, the red-giant branch and the white-dwarf graveyard, and you can watch a star of any mass trace its evolutionary track across it.
Steer the Moon through its tilted orbit and watch shadow cones line up the Sun, Earth and Moon into total, annular and lunar eclipses.
Climb the cosmic distance ladder rung by rung — radar in the solar system, the parallax wobble of nearby stars, pulsating Cepheids and Type Ia supernovae as standard candles, and Hubble’s law to the edge of the visible universe — each method calibrating the next across more than twenty orders of magnitude.
Thousands of asteroids ride Keplerian orbits between Mars and Jupiter — and the Kirkwood gaps open up exactly at the mean-motion resonances where Jupiter clears them.
SpaceX の各フライトをミッションコンソールとして表示します——成功と失敗のマーカー付きでスクロールできる飛行ログ、ライブの成功率ゲージ、そして打ち上げごとのパッチとリンクをまとめたドシエ。
八つの惑星がケプラー要素にしたがって太陽を周回します。「見栄え」を優先した誇張スケールと、実際の縮尺どおりのモードを切り替えて、宇宙がどれほど空っぽかを体感してください。
