Although it shares a similar size to that of a star, its mass and other characteristics differentiate it from conventional stars that orbit in the Milky Way. NASA has indicated that <strong>it could be a low-mass star or a brown dwarf<\/strong>. The latter are celestial bodies that, unlike stars, do not manage to constantly fuse hydrogen in their cores. Among the 4,000 brown dwarfs discovered in WISE data, none have been observed traveling into intergalactic space like CWISE J1249 does.<\/p>\n\n\n\n<p>Another intriguing factor is its composition, as it contains much less iron and other metals compared to typical stars and brown dwarfs, <strong>suggesting that it is a very ancient object<\/strong>, possibly originating from one of the first generations of stars in our galaxy.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"720\" height=\"540\" src=\"https:\/\/articles-img.sftcdn.net\/sft\/articles\/auto-mapping-folder\/sites\/3\/2024\/08\/Comparativa-tamano-estrella-enan.jpg?GoogleAccessId=wp-stateless%40kubertonic.iam.gserviceaccount.com&#038;Expires=1778355337&#038;Signature=Je3uY34glfOn%2BKD%2B9xuGID%2Bovh2%2BcKEtlr3%2FGvmXKjcqW14bTz%2Bro58g8%2BUZUfuNkfJa389I8xKEckzbJZzZa9nwv%2Ba4%2FdxLCOITwQWosGQ8jVLsGhNujMtjanyIr1xD0mHT%2B52UsZ13wrQlR2jjS2zEyZ8kl8Pu3Cnl0hHsZ06h6GccpjwGFQ0sdJdkSiRGpelcn%2B2HUCrNMArBJZathffm44DGP8IMwNW9j0UH2N5dFNU7HHW2O1Qo7gudv2k60alSGGA86%2FDErqru0NusQOnC0UuvsfbqlnOo8ipfFXpoDzw7lIx%2BEZy2o5dcVJRV5E2VVawOUgwIStZdJ0GjeQ%3D%3D\" alt=\"\" class=\"wp-image-287372\" \/><\/figure>\n<\/div>\n\n\n<p>Scientists are puzzled by the incredible speed of CWISE J1249. One of the proposed theories suggests that the object originated in a binary system with <strong>a white dwarf that exploded as a supernova<\/strong>. Another possibility is that it was expelled from a globular cluster after <strong>a close encounter with a pair of supermassive black holes<\/strong>. According to <strong>Kyle Kremer<\/strong>, assistant professor in the Department of Astronomy and Astrophysics at the University of California, San Diego, &#8220;when a star encounters a binary black hole, the complex dynamics of this three-body interaction can launch it out of the globular cluster.&#8221;<\/p>\n\n\n<div class=\"sc-card-program\">\r\n  <div class=\"sc-card-program__body\">\r\n    <div class=\"sc-card-program__row clearfix\">\r\n      <div class=\"sc-card-program__col-logo\">\r\n        <img decoding=\"async\" class=\"sc-card-program__img\" alt=\"NASA App\" src=\"https:\/\/images.sftcdn.net\/images\/t_app-icon-s\/p\/2cddcc48-a4d6-11e6-88af-00163ec9f5fa\/3678680588\/nasa-app-logo\" width=\"100px\" height=\"100px\">\r\n      <\/div>\r\n      <div class=\"sc-card-program__col-title\">\r\n        <span class=\"sc-card-program__title\">NASA App<\/span>\r\n        <a class=\"sc-card-program__button sc-card-program-internal\" href=\"https:\/\/nasa-app.en.softonic.com\/android\" target=\"_self\" rel=\"noopener noreferrer\">DOWNLOAD<\/a>\r\n      <\/div>\r\n      <div class=\"sc-card-program__col-rating\">\r\n        <svg class=\"rating-score__content\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" version=\"1.1\" x=\"0\" y=\"0\" viewbox=\"0 0 50 50\" enable-background=\"new 0 0 50 50\" xml:space=\"preserve\"><path class=\"rating-score__background rating-score--good\" fill=\"none\" stroke-width=\"6\" stroke-miterlimit=\"10\" d=\"M40 40c8.3-8.3 8.3-21.7 0-30s-21.7-8.3-30 0 -8.3 21.7 0 30\"><\/path><path class=\"rating-score__value rating-score__value--0\" fill=\"none\" stroke-width=\"6\" stroke-dashoffset=\"0\" stroke-miterlimit=\"10\" d=\"M40 40c8.3-8.3 8.3-21.7 0-30s-21.7-8.3-30 0 -8.3 21.7 0 30\"><\/path><text class=\"rating-score__number\" content=\"\" text-anchor=\"middle\" transform=\"matrix(1 0 0 1 25 31.0837)\" data-auto=\"app-user-score\"><\/text><\/svg>\r\n      <\/div>\r\n    <\/div>\r\n    <div class=\"sc-card-program__row\">\r\n      <span class=\"sc-card-program__description\"><\/span>\r\n    <\/div>\r\n    <div class=\"sc-card-program__row\">\r\n      <img decoding=\"async\" class=\"sc-card-program__bigpic\" src=\"\" onerror=\"this.style.display='none'\">\r\n    <\/div>\r\n    <a class=\"sc-card-program__link track-link sc-card-program-internal\" href=\"https:\/\/nasa-app.en.softonic.com\/android\" target=\"_self\" rel=\"noopener noreferrer\"><\/a>\r\n  <\/div>\r\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>NASA has echoed the discovery in the Milky Way of an unusual celestial object that is moving at a speed of one million kilometers per hour, which could lead it to leave our galaxy.
