Description:
By observing 25 massive galaxy clusters with HST's new panchromatic imaging capabilities (Wide-field Camera 3, WFC3, and the Advanced Camera for Surveys, ACS), CLASH will accomplish its four primary science goals:
- Map, with unprecedented accuracy, the distribution of dark matter in galaxy clusters using strong and
weak gravitational lensing;
- Detect Type Ia supernovae out to redshift z ~ 2, allowing us to test the constancy of dark energy's
repulsive force over time and look for any evolutionary effects in the supernovae themselves;
- Detect and characterize some of the most distant galaxies yet discovered at z > 7 (when the Universe
was younger than 800 million years old - or less than 6% of its current age);
- Study the internal structure and evolution of the galaxies in and behind these clusters.
Deep Optical Photometry of Six Fields in the Andromeda Galaxy

Description:
Using the Advanced Camera for Surveys on the Hubble Space Telescope, Thomas Brown
(STScI) et al. obtained deep optical images reaching well below the oldest main
sequence turnoff in six fields of the Andromeda Galaxy. The fields fall at four
positions on the southeast minor axis, one position in the giant stellar stream,
and one position on the northeast major axis. These data were obtained as part of
three large observing programs (9453, 10265, 10816) designed to probe the star
formation history of the stellar population in various structures of the galaxy.
Hubble Infrared Pure Parallel Imaging Extragalactic Survey (HIPPIES)
Short Name:
HST.HIPPIES

Space Telescope Science Institute Archive
Description:
Hubble Infrared Pure Parallel Imaging Extragalactic Survey (HIPPIES) utilizes long-duration pure parallel
visits (~> 3 orbits) of HST at high Galactic latitude (|b|>20o) to take deep, multi-band images in WFC3
(since Cycle 17) and in ACS (starting Cycle 18). It is unique in its large number of descrete fields
along random sightlines, and thus is complementary to other surveys over contiguous fields but
along limited sightlines.
