Abell 2597 galaxy cluster, composite image
Abell 2597 galaxy cluster. Composite image of the galaxy cluster Abell 2597, showing the fountain-like flow of gas powered by the supermassive black hole in the central galaxy. The yellow is ALMA data showing cold gas. The red is data from the MUSE instrument on ESO's Very Large Telescope (VLT), showing the hot hydrogen gas in the same region. The blue-purple is the extended hot, ionized gas as imaged by the Chandra X-ray Observatory (CXO). The yellow ALMA data shows infalling material and the red MUSE data shows material launched in a vast spout by the black hole. ALMA is the Atacama Large Millimeter Array. MUSE is the multi-unit spectroscopic explorer. Abell 2597 is in the constellation of Aquarius. Image published in 2018.
