PPT-Hubble’s Law

Plot distance vs velocity We find Velocity proportional to distance H 0 is called Hubbles constant Best fit today includes many assumptions Uncertainties Until recently we didnt know . They measure atti tude when Hubble is changing its pointing from one target a star or planet for example to anoth er and they help control the telescopes pointing while scientists are observing targets Three gyros must operate simultaneously to prov Hubble 2006: Science Year in Review These Hubble snapshots reveal dramatic activities within the core of the galaxy NGC 3079, where a lumpy bubble of hot gas is rising from a cauldron of glowing ma Homogeneous and uniform cosmic expansion .
