Pan across galaxy cluster Abell 1689
September 12, 2013 · ESA/Hubble
This video pans across a new Hubble image of galaxy cluster Abell 1689. This cluster acts like a cosmic lens, magnifying the light from objects lying behind it and making it possible for astronomers to explore incredibly distant regions of space.
This new image combines visible and infrared data from Hubble’s Advanced Camera for Surveys (ACS) to reveal this patch of sky in greater detail than ever before, with a combined total exposure time of over 34 hours.
