Galaxies & the Universe

Leave the solar system behind. Spin a 3D Milky Way and find our Sun among its hundreds of billions of stars, evolve stars from nebula to black hole, and ride a powers-of-ten zoom from the summit of Everest to the cosmic horizon 93 billion light-years wide.

You will learn: doneGalaxy structure and our place in it doneLight-years and cosmic distances doneStellar evolution and fusion doneSupernovae, neutron stars, black holes donePowers-of-ten thinking
