HH 30 in Taurus has been imaged with the Hubble Space T elescope WFPC2. The images
show in re—ected light a—ared disk with a radius of about 250 AU that obscures the protostar…

We discuss the photometric performance and calibration of the Wide Field Planetary Camera
2 (WFPC2) on the Hubble Space Telescope (HST). The stability and accuracy of WFPC2 …

We may now examine in more detail the causes of vegetation changes, chiefly through
experiments or observations which ecologists have carried out on the redevelopment of forest …

We measure the morphology-density relation (MDR) and morphology-radius relation (MRR)
for galaxies in seven z~ 1 clusters that have been observed with the Advanced Camera for …

… was used to determine the small remaining aberrations (Burrows and Krist 1994). As a result
… A more detailed description of HST and WFPC2 optical parameters is given in Burrows and …

We analyze deep multicolor Advanced Camera images of the largest known gravitational
lens, A1689. Radial and tangential arcs delineate the critical curves in unprecedented detail, …

Reactive oxygen species (ROS) have emerged as important cellular-signaling agents for
cellular survival. Herein, we demonstrate that ROS-mediated oxidation of DNA to yield 8-oxo-7,…
