New analysis on 2017 Hubble images of the Jupiter-family comet, 41P/Tuttle–Giacobini–Kresak (41P/TGK), indicates that the comet underwent a spin reversal between April and December 2017. While this behavior is not unheard of, 41P/TGK's rotational changes were deemed "particularly dramatic" in the new paper published on the arXiv preprint server.
