New observations of the galaxy cluster SPT-CLJ2344-4243 at X-ray, ultraviolet, and optical wavelengths are helping astronomers better understand this extraordinary system. Chandra data (blue) reveal large cavities in the X-rays, which have been combined in this composite image with optical data from Hubble (red, green, and blue). Astronomers think these X-ray cavities were carved out of the surrounding gas by powerful jets of high-energy particles emanating from near a supermassive black hole in the central galaxy of the cluster. Massive filaments of gas and dust, which extend for 160,000 to 330,000 lights years, surround the X-ray cavities.
