NASA’s Chandra X-ray Observatory unveils color-coded images exposing shock waves, cooling gas, and black hole-carved cavities in galaxy clusters. The new “X-arithmetic” technique highlights invisible cosmic processes shaping the universe’s largest structures.
The Chandra X-ray Observatory of NASA has publicised brightly coloured colour-coded images of huge galaxy clusters, which expose the dark secrets of the universe in terms of structures and the processes that are very active in shaping the largest structures in the universe. With the aid of colours to distinguish the different energies of X-rays, astronomers are able to emphasise shock waves, cooling gas, and cavities left behind by gigantic black holes, which are normally not visible to the human eye.
A Clearer Look at Invisible Cosmic Activity
According to NASA, the new Chandra technique, which is frequently referred to as "X-arithmetic," separates the X-ray light according to energy and assigns each band a different colour. In this way, one can very quickly see the different astrophysical components of a cluster: for example, areas coloured yellow represent the bubbles that black hole jets have blown, the blue colour shows cooler or more dense gas, and the pink colour follows the faint shock fronts or the ripples similar to sound waves that are spreading in the hot plasma.
