The Hubble Space Telescope has witnessed a spinning comet slow its own rotation and then start spinning in the opposite direction, in the first observation of its kind demonstrating that comets can be even more dynamic than we thought.
Comet 41P/Tuttle–Giacobini–Kresák is a Jupiter-family comet, meaning that it is a short-period comet (orbiting the sun every 5.4 years) that has come in from the Kuiper Belt before being snagged by Jupiter's gravity.
