Planets, Stars, Galaxies, and the Universe



We are now nearing the edge of the observable Universe. From our start, considering the sky seen from Earth, we have progressed through the Milky Way, to the local galaxy neighborhood, and have seen some of the most distant galaxies astronomers have detected. You now have been introduced to almost every type of object astronomers have identified. The next goal is to try to explain where it all came from, and what may be its fate.
