Chandra Release - September 18, 2024

Visual Description: Zwicky 8338 

This release features a composite image of two pairs of hot gas tails found inside a single galaxy cluster. The image is presented both labeled and unlabeled, with color-coded ovals encircling the hot gas tails.

In both the labeled and unlabeled versions of the image, mottled purple gas speckles a region of space dotted with distant flecks of red and white. Also present in this region of space are several glowing golden dots. These dots are individual galaxies that together form the cluster Zwicky 8338.  

To our right of center is a glowing golden galaxy with a mottled V shaped cloud of purple above it. Yellow labels identify the two arms of the V as tails trailing behind the hurtling galaxy below. 

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