Since its launch 25 Years ago, the Hubble Telescope has returned images of unprecedented beauty of a dynamic and changing universe. In this episode of COSMIC JOURNEYS, Hubble’s most iconic images are bought to life to answer some of the most important questions facing astronomers today. Colliding galaxies, the birth and death of stars, jets of gas thrown out by material crashing into distant suns: these incredible images tech us valuable lessons about how galaxies are formed, what dark matter is and even the fate of the earth itself.
