A formation in vivid blue. Text, July 23, 2021. Galaxy Cluster Collision.
 
New data from NASA's Chandra X-ray Observatory adds to evidence of an ongoing galaxy cluster collision in Abell 1775

 
(DESCRIPTION)
Structure and Chandra's data indicates that a smaller galaxy cluster is passing through a larger one.
 
Radio data of the same area shows a huge jet powered by a supermassive black hole.
 
Together, a multi-wavelength data shows the jet's structure change abruptly as it moves through different gas densities caused by the collision.
 
While Chandra data confirms the clusters are colliding, questions remain about the formation of the bright, curving structure shown in the clusters’ intersecting gas.
