Interdisciplin\u0101ras diskusijas par kom\u0113tas st\u0101vokli<\/p>\n
Starpzvaig\u017e\u0146u kom\u0113ta 3I\/ATLAS, visticam\u0101k, ir saglab\u0101jusi savu integrit\u0101ti p\u0113c projugas gar\u0101m Saulei, neskatoties uz pla\u0161i izplat\u012btaj\u0101m spekul\u0101cij\u0101m, ka t\u0101 b\u016btu uzspr\u0101gusi un sadal\u012bjusies da\u013c\u0101s. \u0160\u0101di apgalvojumi rad\u0101s p\u0113c tam, kad izdevums Futurism zi\u0146oja par kom\u0113tas fragment\u0101ciju, kad t\u0101 atkal par\u0101d\u012bj\u0101s no Saules aizmugures. \u0160\u012b interpret\u0101cija da\u013c\u0113ji balst\u012bj\u0101s uz astrofizi\u0137a Avi L\u0113ba no H\u0101rvardas Universit\u0101tes bloga ierakstiem, kur vi\u0146\u0161, analiz\u0113jot divu nelielu teleskopu ieg\u016btos datus Sp\u0101nij\u0101, apr\u0113\u0137in\u0101ja, ka 3I\/ATLAS zaud\u0113jusi iev\u0113rojamu da\u013cu savas masas.<\/p>\n
A. L\u0113bs \u0161aj\u0101 sakar\u0101 atkal izvirz\u012bja hipot\u0113zi, ka 3I\/ATLAS var\u0113tu b\u016bt \u0101rzemju kosmosa ku\u0123is. Tom\u0113r liel\u0101k\u0101 da\u013ca astronomijas ekspertu pieturas pie nost\u0101jas, ka kom\u0113ta ir izdz\u012bvojusi p\u0113c peri\u0113lija (punkta, kas vistuv\u0101k Saulei) un nav nek\u0101ds m\u0101ksl\u012bgs objekts. Tiek uzsv\u0113rts, ka vizu\u0101lie dati neatbalsta ideju par kom\u0113tas sabruk\u0161anu.<\/p>\n
Astronomu nov\u0113rojumi un pier\u0101d\u012bjumi par kom\u0113tas veselumu<\/p>\n
\u201eVisos att\u0113los, ko esmu redz\u0113jis, kom\u0113ta izskat\u0101s piln\u012bgi norm\u0101li un neskarta. Nav nek\u0101du paz\u012bmju, kas liecin\u0101tu par kodola sadal\u012b\u0161anos,\u201d nor\u0101da Cihcins D\u017eans (Cichen Zhang), zin\u0101tniskais l\u012bdzstr\u0101dnieks no Lova observatorijas Arizon\u0101. \u0160ie apgalvojumi ir b\u016btiski, jo 3I\/ATLAS sasniedza savu peri\u0113liju 29. oktobr\u012b. P\u0113c tam astronomi pastiprin\u0101ti seko kom\u0113tas gaitai, cen\u0161oties ieg\u016bt p\u0113c iesp\u0113jas vair\u0101k inform\u0101cijas par t\u0101s sast\u0101vu.<\/p>\n

Skeptisms par Avi L\u0113ba teorij\u0101m<\/p>\n
Liel\u0101k\u0101 da\u013ca astronomu ir p\u0101rliecin\u0101ti, ka \u0161is sve\u0161zemju viesis ir parasta kom\u0113ta no nezin\u0101mas zvaig\u017e\u0146u sist\u0113mas M\u0113ness apkaim\u0113. Avi L\u0113bs, analiz\u0113jot izmest\u0101s vielas apjomu un 3I\/ATLAS masu, secin\u0101ja, ka, ja t\u0101 b\u016btu tradicion\u0101la kom\u0113ta, tai vajadz\u0113tu b\u016bt iev\u0113rojami liel\u0101kai par nov\u0113roto laukumu. Vi\u0146\u0161 ar\u012b apgalvoja, ka p\u0113c Saules p\u0101rlidojuma kom\u0113tai bija j\u0101sadal\u0101s vismaz 16 fragmentos, un ja tas nav noticis, to nedr\u012bkst uzskat\u012bt par dabisku kosmisku objektu.<\/p>\n
\u201cEs p\u0101rbaud\u012bju Avi L\u0113ba blogu, un \u0161\u0137iet, ka vi\u0146\u0161 ir uzc\u0113lis k\u0101r\u0161u nami\u0146u, pamatojoties uz savu nepamatoto apgalvojumu par kom\u0113tas pa\u0101trin\u0101jumu, kas ir ac\u012bmredzams kom\u0113tas orb\u012btas parametru sagroz\u012bjums, un ikviens, kas jebkad ir apr\u0113\u0137in\u0101jis kom\u0113tas orb\u012btu, uzreiz saprat\u012bs, ka t\u0101 ir k\u013c\u016bda,\u201d \u2013 nor\u0101da Cihcins D\u017eans.<\/p><\/blockquote>\n
Piem\u0113ram, amatieru astronomu Maikla B\u012bhnera un Franka N\u012bblinga 9. novembr\u012b uz\u0146emtajos att\u0113los redzamas kom\u0113tas izmest\u0101s str\u016bklas, kas liecina par akt\u012bvu sublim\u0101cijas procesu, nevis par sadal\u012b\u0161anos.<\/p>\n
Rivaliz\u0113jo\u0161ie p\u0113t\u012bjumi un gaid\u0101mie notikumi<\/p>\n
D\u017eeisons Raits (Jason Wright), Pensilv\u0101nijas \u0161tata universit\u0101tes profesors astronomij\u0101 un astrofizik\u0101, sav\u0101 blog\u0101 paudis, ka nav nek\u0101du paz\u012bmju, kas liecin\u0101tu par 3I\/ATLAS m\u0101ksl\u012bgo dabu. Vi\u0146\u0161 apstr\u012bd\u0113jis desmit A.

Neskatoties uz teor\u0113tiskiem str\u012bdiem, kom\u0113ta turpina savu ce\u013cu. Tiek prognoz\u0113ts, ka \u0161im starpzvaig\u017e\u0146u viesim b\u016bs maksim\u0101li tuvs att\u0101lums no Zemes 19. decembr\u012b. \u0160\u012b ir otr\u0101 zin\u0101m\u0101 kom\u0113ta, kas ierodas no citas zvaig\u017e\u0146u sist\u0113mas (p\u0113c 1I\/’Oumuamua), un t\u0101s turpm\u0101ka izp\u0113te var sniegt unik\u0101lu inform\u0101ciju par cit\u0101m galaktikas da\u013c\u0101m.<\/p>\n
