The Supernova Cosmology Project has previously presented data from 42 Type Ia supernovae which set limits on the cosmological mass density Ω M and provided evidence for a cosmological constant Ω Λ , implying that the expansion of the universe is currently accelerating. This poster will present the results from an additional 11 Type Ia supernovae discovered in 1998--2000, observed with the Wide Field/Planetary Camera 2 (WFPC2) on the Hubble Space Telescope (HST) in the F675W (R) and F814W (I) filters. The WFPC2 observations of these supernovae provide much better photometric constraints on the lightcurves of the supernovae, yielding in turn a better measurement of the distance modulus to each supernova, particularly at higher redshifts, than was available for the 42 supernovae previously observed from the ground. These new observations improve our measurements of the cosmological parameters Ω M and Ω Λ . This work was supported by the Department of Energy and by the NASA Space Telescope Science Institute.
