Technical facts about this news release:

About Abell 2744:
Object Name: Abell 2744, Pandora's Cluster
Object Description: Galaxy Cluster and Gravitational Lens
Position (J2000): R.A. 00h14m 19s.51
Dec. -30° 23' 19".18
Constellation: Sculptor
Redshift: z=0.308
Data Description: Data were obtained as part of the HST proposal 11689: R. Dupke (Eureka Scientific Inc.) et al.
Exposure Dates: October 27-30, 2009
Instruments, Filters,
and Colors:
This image is a composite of separate exposures acquired by the ACS instrument on the Hubble Space Telescope (HST). Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
ACS/WFC F814W (I) red
ACS/WFC F606W (V) green
ACS/WFC F435W (B) blue
About MACS J0416.1-2403:

Redshift: z=0.396
Data Description: Data were obtained as part of the HST proposal 12459: M. Postman (STScI) and the CLASH Team
Exposure Dates: July - September, 2012
Instruments, Filters,
and Colors:
This image is a composite of separate exposures acquired by the ACS and WFC3 instruments on the Hubble Space Telescope (HST). Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are:
WFC3/IR F105W (Y)+F110W (YJ)+F125W (J)+F160W (H) red
ACS/WFC F775W (i) green
ACS/WFC F435W (B) blue
