Researchers have discovered a second pair of tails trailing behind a galaxy in this cluster. Previously, astronomers discovered a shorter pair of tails from a different galaxy close to this latest one. This newer and longer set of tails was only seen because of a deeper observation with Chandra that revealed the fainter X-rays that have been shown in the optical data. These tails span for over a million light-years and help determine the evolution of the galaxy cluster.

This tactile plate is a physical relief map based on the intensity of X-ray and Optical data, depicting two pairs of hot gas tails found inside a single galaxy cluster in the X-ray data from Chandra. This plate is presented unlabeled.

Mottled gas speckles a region of space dotted with distant flecks. Also present in this region of space are several larger dots. These dots are individual galaxies that together form the cluster Zwicky 8338.

To our right of center is a galaxy with a mottled V shaped cloud above it. This cloud represents two tails trailing behind the hurtling galaxy below.

To our left of center is another raised bump of a galaxy, this one surrounded by gas. Behind it, opening toward our right in the shape of a widening V lying on its side, are two more mottled clouds. These newly-discovered gas tails are even larger than the previously discovered tails. These tails, which overlap with the galaxy on our right, are over 1.6 million light-years long.
