First Exomoon Candidate Detected via Radial Velocity in CD-35 2722 System

ESO's VLT, using the CRIRES+ spectrograph, detected radial velocity wobbles on a 30+ Jupiter-mass brown dwarf in the CD-35 2722 system, revealing a companion at least as massive as Jupiter. Published in Nature on 22 July 2026, the finding would be the first exomoon confirmed — though the team calls it an "exosatellite," reflecting the classification debate the detection has triggered.
