Solar System Hệ Mặt Trời
8 planets orbit the Sun — true size & speed ratios, real surface colors, click for an interior cross-section.
Comet Sao chổi
A ball of ice & dust racing along a stretched ellipse — its gas and dust tails always stream away from the Sun.
Black Hole Hố đen
A gravity well that swallows even light — event horizon, glowing accretion disk & warped spacetime.
Galaxy Thiên hà
A giant island of stars — the spiral Milky Way with hundreds of billions of stars, a disk, arms & a dark halo.
Universe Vũ trụ
All of spacetime — the Big Bang, ceaseless expansion & the cosmic web of galaxies.
Earth–Moon & Tides Trái Đất – Mặt Trăng
The Earth–Moon system to true scale: a tidally locked Moon, two tidal bulges, spring–neap tides set by the Sun.
Eclipses Nhật & Nguyệt thực
Sun–Earth–Moon shadow cones sweep for real: the Sun’s disk is covered → corona, the Moon turns red (blood moon).
Rocket & Orbit Bệ phóng & Quỹ đạo
Launch a gravity-turn rocket to orbit with real Tsiolkovsky physics; tune thrust, staging, the delta-v budget.
Habitable Zone Vùng sống được
The habitable zone shifts with star type; drag a planet in and out: liquid water in green, too close boils, too far freezes.
Exoplanet Transit Săn ngoại hành tinh
A planet crossing the stellar disk → a U-shaped dip in the light curve; phase-fold many cycles to pull the signal from noise.
Star Lifecycle Vòng đời sao
A star creeps along its evolutionary track on the HR diagram — born, swelling into a red giant, then dying by mass & time.
Star Forge Lò sinh sao
A gas-dust cloud collapses into an accretion disk then ignites fusion + fires bipolar jets; mass decides which star is born.
Supernova Siêu tân tinh
The iron core collapses → an explosion blasts off the outer layers, seeding heavy elements → leaving a neutron star/pulsar or black hole.
Quasar / AGN Quasar & Nhân thiên hà
A supermassive black hole devours matter → a blazing accretion disk + twin near-light-speed plasma jets (the brightest objects in the universe).
Asteroids & Belts Tiểu hành tinh
The rocky belt between Mars & Jupiter with Kirkwood gaps, Trojan swarms, the icy Kuiper Belt & the Oort Cloud wrapping the Solar System.
Gravitational Waves Sóng hấp dẫn
Two black holes / neutron stars spiral in, warping & ringing the sheet of spacetime — ripples spread, a ‘chirp’ reaching the LIGO detector.
Binary Stars Hệ sao đôi
Two stars orbit a shared center of mass, pour gas across the Roche lobe into an accretion disk, and eclipse each other into a telltale light curve (Algol · Sirius · nova).
Mars & Terraforming Sao Hỏa
The red planet with polar ice caps & 2 moons — drag the ‘terraform’ slider to turn it green with seas, plants & sky (or watch the solar wind strip its atmosphere).
Pulsar Sao xung / Sao neutron
An incredibly dense neutron star spinning fast, firing two lighthouse-like beams — each sweep past us reads as a perfectly regular pulse.
Gravitational Lensing Thấu kính hấp dẫn
A huge mass bends passing light — a background galaxy appears as an Einstein ring, double image or arc. How we ‘weigh’ even dark matter.
