We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST ) and have used them to trace the history of cosmic expansion over the last 10 billion yr. These objects, which include 13 spectroscopically confirmed SNe Ia at z 1, were discovered during 14 epochs of reimaging of theGOODSfields North and South over 2 yr with the(More)
