Zooming In On CLASS B1608+656

April 17, 2014

This video begins with a view of the night sky before zooming in towards galaxy cluster CLASS B1608+656. It homes in first on a view of the area around the cluster from the Digitized Sky Survey (produced with a ground-based telescope), before focusing on Hubble observations of the cluster.

Hubble’s very long exposure (14 hours) combined with advanced instrumentation and a unique location above the distorting atmosphere means that its observations are both much sharper and much brighter than those taken from the ground-based telescope. Hubble’s image is clearly visible as a square of brighter galaxies near the end of the zoom video.
