Chaotic ‘knot’ of merging galaxy clusters captured in multiple wavelengths

Some 780 million light-years from Earth, at least three galactic clusters are undergoing a chaotic merger, and using data from a variety of telescopes, astronomers captured the massive collision in a striking new image.

The smaller galactic clusters, each of which comprises hundreds or thousands of individual galaxies, are combining to form an even larger galactic cluster known as Abell 2256.
