Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus.\u00a0<\/div>\n<div class=\"hds-credits\">Image: NASA, ESA, David Jewitt (UCLA); Image Processing: Joseph DePasquale (STScI)<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\n<p>A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet <a href=\"https:\/\/science.nasa.gov\/solar-system\/comets\/3i-atlas\/\" rel=\"noopener\">3I\/ATLAS<\/a> using the crisp vision of NASA\u2019s <a href=\"https:\/\/science.nasa.gov\/mission\/hubble\/\" rel=\"noopener\">Hubble Space Telescope<\/a>. Hubble is one of many missions across NASA\u2019s fleet of space telescopes slated to observe this comet, together providing more information about its size and physical properties. While the comet poses no threat to Earth, NASA\u2019s space telescopes help support the agency\u2019s ongoing mission to find, track, and better understand near-Earth objects.<\/p>\n<p>Hubble\u2019s observations allow astronomers to more accurately estimate the size of the comet\u2019s solid, icy nucleus. The upper limit on the diameter of the nucleus is 3.5 miles (5.6 kilometers), though it could be as small as 1,000 feet (320 meters) across, researchers report. Though the Hubble images put tighter constraints on the size of the nucleus compared to previous ground-based estimates, the solid heart of the comet presently cannot be directly seen, even by Hubble. Observations from other NASA missions including the <a href=\"https:\/\/science.nasa.gov\/mission\/webb\/\" rel=\"noopener\">James Webb Space Telescope<\/a>, <a href=\"https:\/\/science.nasa.gov\/mission\/tess\/\" rel=\"noopener\">TESS<\/a> (Transiting Exoplanet Survey Satellite), and the <a href=\"https:\/\/science.nasa.gov\/mission\/swift\/\" rel=\"noopener\">Neil Gehrels Swift Observatory<\/a>, as well as NASA\u2019s partnership with the <a href=\"https:\/\/keckobservatory.org\/\"  rel=\"noreferrer noopener\">W.M. Keck Observatory<\/a>, will help further refine our knowledge about the comet, including its chemical makeup.<\/p>\n<p>Hubble also captured a dust plume ejected from the Sun-warmed side of the comet, and the hint of a dust tail streaming away from the nucleus. Hubble\u2019s data yields a dust-loss rate consistent with comets that are first detected around 300 million miles from the Sun. This behavior is much like the signature of previously seen Sun-bound comets originating within our solar system.<\/p>\n<p>The big difference is that this interstellar visitor originated in some other solar system elsewhere in our Milky Way galaxy.<\/p>\n<p>3I\/ATLAS is traveling through our solar system at a staggering 130,000 miles (209,000 kilometers) per hour, the highest velocity ever recorded for a solar system visitor. This breathtaking sprint is evidence that the comet has been drifting through interstellar space for many billions of years. The gravitational slingshot effect from innumerable stars and nebulae the comet passed added momentum, ratcheting up its speed. The longer 3I\/ATLAS was out in space, the higher its speed grew.<\/p>\n<p>\u201cNo one knows where the comet came from. It\u2019s like glimpsing a rifle bullet for a thousandth of a second. You can\u2019t project that back with any accuracy to figure out where it started on its path,\u201d said David Jewitt of the University of California, Los Angeles, science team leader for the Hubble observations.<\/p>\n<p>The paper will be published in <a href=\"https:\/\/journals.aas.org\/astrophysical-journal-letters\/\"  rel=\"noreferrer noopener nofollow\">The Astrophysical Journal Letters<\/a>. It is already available on <a href=\"https:\/\/arxiv.org\/abs\/2508.02934\" rel=\"noopener\">Astro-ph<\/a>.<\/p>\n<h3 class=\"wp-block-heading\">New Evidence for Population of Wandering Space Relics<\/h3>\n<p>\u201cThis latest interstellar tourist is one of a previously undetected population of objects bursting onto the scene that will gradually emerge,\u201d said Jewitt. \u201cThis is now possible because we have powerful sky survey capabilities that we didn\u2019t have before. We\u2019ve crossed a threshold.\u201d<\/p>\n<p>This comet <a href=\"https:\/\/science.nasa.gov\/blogs\/planetary-defense\/2025\/07\/02\/nasa-discovers-interstellar-comet-moving-through-solar-system\/\" rel=\"noopener\">was discovered<\/a> by the NASA-funded <a href=\"https:\/\/fallingstar.com\/home.php\"  rel=\"noreferrer noopener\">Asteroid Terrestrial-impact Last Alert System<\/a> (ATLAS) on July 1, 2025, at a distance of 420 million miles from the Sun. ATLAS is an asteroid impact early warning system developed by the University of Hawai\u2019i.\u00a0<\/p>\n<p>In the meantime, other NASA missions will provide new insight into this third interstellar interloper, helping refine our understanding of these objects for the benefit of all. 3I\/ATLAS should remain visible to ground-based telescopes through September, after which it will pass too close to the Sun to observe, and is expected to reappear on the other side of the Sun by early December.<\/p>\n<figure class=\"wp-block-embed alignwide is-type-video is-provider-youtube wp-block-embed-youtube\">\n<div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Interstellar Visitor is Fastest Comet Ever Recorded\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/pc4A8va8NRU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div>\n<\/figure>\n<p><em>The Hubble Space Telescope has been operating for more than three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe.
