The lonely galaxy 3C 297, located 9.2 billion light-years from Earth, has unique characteristics typically found in galaxy clusters. Astronomers suggest it may be a “fossil group,” absorbing former companion galaxies, making it the most distant fossil group ever discovered. Credit: X-ray: NASA/CXC/Univ. of Torino/V.

This image features a galaxy called 3C 297 that is lonelier than expected after it likely pulled in and absorbed its former companion galaxies. The solo galaxy is located about 9.2 billion light-years from Earth and contains a quasar, a supermassivepulling in gas at the center of the galaxy and driving powerful jets of matter seen in radio waves.
