This is the first time researchers have observed evidence of a comet reversing its spin.\u00a0<\/p>\n<p>The object, comet 41P\/Tuttle-Giacobini-Kres\u00e1k, or 41P for short, likely originated in the Kuiper Belt, and was flung into its current trajectory by Jupiter\u2019s gravity, now visiting the inner solar system every 5.4 years.<\/p>\n<p>After its 2017 close passage around the Sun, scientists found that comet 41P experienced a dramatic slowdown in its rotation. <a href=\"https:\/\/www.nasa.gov\/solar-system\/nasas-newly-renamed-swift-mission-spies-a-comet-slowdown\/\" rel=\"noopener\">Data from NASA\u2019s Neil Gehrels Swift Observatory in May 2017<\/a> showed the object was spinning three times more slowly than it had in March 2017 when it was observed by the Discovery Channel Telescope at Lowell Observatory in Arizona.<\/p>\n<p>A new analysis of follow-up Hubble observations has shown the spin of this comet took an even more unusual turn.<\/p>\n<p>Hubble images from December 2017 detected the comet spinning much faster again, with a period of approximately 14 hours, compared to the 46 to 60 hours measured by Swift. The simplest explanation, researchers say, is that the comet continued slowing until it almost stopped, and was then forced to spin in the near-opposite direction by outgassing jets on its surface.<\/p>\n<p>The <a href=\"https:\/\/iopscience.iop.org\/article\/10.3847\/1538-3881\/ae4355\"  rel=\"noreferrer noopener nofollow\">science paper<\/a> detailing this finding published Thursday in The Astronomical Journal.<\/p>\n<div id=\"\" class=\"hds-media hds-module wp-block-image\">\n<div class=\"margin-left-auto margin-right-auto nasa-block-align-wide\">\n<div class=\"hds-media-wrapper margin-left-auto margin-right-auto\">\n<figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><img decoding=\"async\" loading=\"lazy\" width=\"2048px\" height=\"2048px\" data-no-id=\"true\" sizes=\"auto, (max-width: 2048px) 100vw, 2048px\" srcset=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/hubble\/releases\/2026\/03\/STScI-01KKH8ZMJNEDZ0VG0TN1HS3VQQ.tif?w=2048 2048w\" alt=\"Illustration, close up of rocky, potato-shaped body of a comet with detailed, cratered surface at the bottom right.

Because the jets kept pushing, they ultimately caused the comet to start rotating in the opposite direction.<\/p>\n<p>\u201cIt\u2019s like pushing a merry-go-round,\u201d said Jewitt. \u201cIf it\u2019s turning in one direction, and then you push against that, you can slow it and reverse it.\u201d<\/p>\n<p><strong>Evidence of rapid evolution<\/strong><\/p>\n<p>The study also shows that the comet\u2019s overall activity has declined significantly since earlier returns. During its 2001 perihelion passage, 41P was unusually active for its size. By 2017, its gas production had decreased by roughly an order of magnitude.<\/p>\n<p>This change suggests that the comet\u2019s surface may be evolving quickly, possibly as near-surface volatile materials become depleted or covered by insulating dust layers.<\/p>\n<p>Most changes in comet structure occur over centuries or longer. The rapid rotational shifts observed in comet 41P provide a rare opportunity to witness evolutionary processes unfolding on a human timescale.\u00a0<\/p>\n<p>Modeling based on the measured torques and mass loss rates suggest that continued rotational changes could eventually lead to structural instability for comet 41P. If a comet spins too rapidly, centrifugal forces can overcome its weak gravity and strength, potentially causing fragmentation or even <a href=\"https:\/\/science.nasa.gov\/missions\/hubble\/hubble-takes-close-up-look-at-disintegrating-comet\/\" rel=\"noopener\">disintegration<\/a>.<\/p>\n<p>\u201cI expect this nucleus will very quickly self-destruct,\u201d said Jewitt.<\/p>\n<p>Yet, comet 41P has likely occupied its present orbit for roughly 1,500 years.\u00a0<\/p>\n<div id=\"\" class=\"width-full maxw-full margin-left-auto margin-right-auto hds-media-align-wide hds-module wp-block-nasa-blocks-video\">\n<div class=\"hds-cover-wrapper width-full maxw-full flex-column\">\n<div class=\"hds-video-container width-full embed-container\" style=\"\"><video title=\"Comet 41P Reversal Animation\" id=\"nasa-plus-PUaVh\" class=\"video-js video-player vjs-fluid width-full\" data-setup='{\"controls\":true,\"preload\":\"auto\",\"plugins\":{\"mux\":{\"debug\":false,\"data\":{\"env_key\":\"91nns8oppqdfqc44lgo4b1gni\",\"player_name\":\"www.nasa.gov Player\",\"video_name\":\"Comet 41P Reversal Animation\"}}}}'  poster=\"https:\/\/assets.science.nasa.gov\/dynamicimage\/assets\/science\/missions\/hubble\/releases\/2026\/03\/STScI-01KKH98DBARS7KQWC3FJEGE8RA.jpg?w=1280&#038;h=720&#038;fit=clip&#038;crop=faces%2Cfocalpoint\" ><source src=\"https:\/\/assets.science.nasa.gov\/content\/dam\/science\/missions\/hubble\/releases\/2026\/03\/STScI-01KMGPETGXSQZ1G83XKWZS45S0.mp4\" type=\"video\/mp4\"><p class=\"vjs-no-js\">To view this video please enable JavaScript, and consider upgrading to a web browser that<br \/>\n\t\t\t\t\t<a href=\"https:\/\/videojs.com\/html5-video-support\/\"  rel=\"noopener\">supports HTML5 video<\/a><\/p><\/video><\/div>\n<\/div>\n<div class=\"hds-media-caption hds-caption padding-y-2\">\n<div class=\"hds-caption-text p-sm margin-0\">\n<div>This artist\u2019s concept depicts comet 41P as it approached the Sun and frozen gases began to sublimate off the comet\u2019s surface.
