A curated gateway into stars, planets, galaxies, nebulae, and the most extreme objects in our universe.
How stars are born, shine, evolve, and end their lives as white dwarfs, neutron stars, or supernovae.
Rocky worlds, gas giants, and icy planets — from Mercury to Neptune and beyond.
Alien worlds orbiting distant stars — hot Jupiters, super-Earths, ocean worlds, and more.
Includes: Life-Candidate Worlds
Proxima b, TRAPPIST-1, Kepler-452b, Europa & Enceladus — places where liquid water and life may be possible.
Spirals, ellipticals, irregulars — cosmic cities with billions of stars and dark matter halos.
Emission, reflection, dark & planetary nebulae — star-forming nurseries and stellar graveyards.
Ancient leftover building blocks of the solar system — sometimes visiting as meteor showers and bright comets.
Stellar, intermediate & supermassive black holes — where gravity is so strong even light cannot escape.
Hyper-energetic cosmic lighthouses and galaxy-powered engines, visible across billions of light-years.
Catastrophic star explosions that forge heavy elements and seed galaxies with the material for new stars and planets.
