- Perihelion ya 3I/ATLAS pa Okutobala 29 pa 1,36 AU (203 miliyoni km) kuchokera ku Dzuwa
- Kutsata kofunikira kuchokera ku Europe: VLT, SOHO/LASCO ndi ESA's JUICE mission
- Siginecha yamankhwala yosazolowereka: mpweya wa nickel wopanda chitsulo wapezeka patali kwambiri
- Masiku omwe akubwera: Venus (November 3), Earth (December 19) ndi Jupiter (Marichi 16, 2026)
Pamene ikuyandikira perihelion, 3I/ATLAS Zakhala cholinga chachikulu cha zakuthambo chifukwa ndi chinthu chachitatu chotsimikizika chapakati pa nyenyezi kuti chidutse pafupi ndi dzuwa. Kuwunika kwake kwa geometry kuchokera ku Earth pafupi ndi tsiku lofunikira sikwabwino, koma Kuyang'anira kogwirizana kuchokera ku Europe ndi malo ena owonera kumapangitsa kuti machitidwe ake azitsatiridwa. ndi tsatanetsatane wodabwitsa.
Kutali ndi mitu yodabwitsa, zomwe zilipo zimaloza ku a comet wamba wokhala ndi mawonekedwe apadera, omwe ma hyperbolic trajectory ndi orbital akuwonetsa ngati mlendo wochokera kunja kwa System dzuwaAsayansi amapezerapo mwayi wophunzira chemistry ndi mphamvu zake, pomwe malingaliro odabwitsa amayesedwa paumboni.
Kodi 3I/ATLAS ndi chiyani ndipo chifukwa chiyani ili yofunika?
Zapezeka pa Julayi 2, 2025 ndi netiweki ya ATLAS, yake Eccentricity wamkulu kuposa 6 ndi liwiro lake ndi ~ 58 km / s Ponena za Dzuwa, iwo anatsimikizira chiyambi chake chapakati pa nyenyezi. Imakhala ndi chikomokere komanso mchira wafumbindi m’masabata aposachedwa adawonetsa "anti-tail" (kapena kuoneka ngati mchira woloza ku Dzuwa) kufotokozedwa ndi momwe zimachitikira komanso kusinthika kwa tinthu, a Chochitika chodziwika mu comets of the Solar System.
Kuphatikiza pa chidwi chake cha orbital, 3I/ATLAS imapereka zenera lapadera lazinthu zakale zopangidwa kunja kwa chilengedwe chathu. Kuwaphunzira kungathe kuwulula ngati midadada yomangira mapulaneti kodi ndi ofanana kudutsa mlalang'amba kapena amasiyana malinga ndi chilengedwe cha nyenyezi?
Madeti ofunikira komanso mtunda wodutsa mu Solar System
Perihelion imapezeka pa Okutobala 29, pafupifupi 11:47 UT, pa 1,36 AU (203 miliyoni km) kuchokera ku DzuwaPatsiku limenelo, kutalika kwa dzuwa sikuli bwino ndipo chinthucho chikutsutsana ndi Dziko lapansi, kotero kuti Kuyang'ana molunjika kuchokera ku dziko lathu lapansi ndizovuta.
Pa Novembara 3, 3I/ATLAS idzayenda pafupifupi 97 miliyoni km kuchokera ku VenusMu sabata lomwelo, geometry yake idzakhala yabwino kwa European JUICE mission, panjira yopita ku Jupiter, kukachita. kuyang'ana kutali popanda kuwala kwa dzuwa pakati.
Kuyandikira kwake kwapafupi kwambiri ndi Dziko Lapansi kukukonzekera Disembala 19, pamtunda wofanana ndi 267 miliyoni Km (njira yokoka yokha). Ngakhale sichikhala chinthu chowala chowoneka ndi maso, chimakonda kuwoneka ndi ma telescope akuluakulu amateur pamlingo wozungulira +11 ngati. zimatulukanso m’mwamba m’mawa.
Kale mu 2026, pa Marichi 16, 3I/ATLAS iyandikira 54 miliyoni km kuchokera ku JupiterM'malo amenewo, kafukufuku wa Juno amatha kuyesa kujambula kapena kuyang'ana pawayilesi pofunafuna mpweya, nthawi zonse malinga ndi kuthekera kwa mishoni komanso zomwe asayansi akhazikitsa.
Ndani akuyang'ana: udindo wa Europe ndi malo akuluakulu owonera
Europe ikuchita mbali yofunika kwambiri. Telescope Yaikulu Kwambiri (VLT) ku ChileTelesikopu, yoyendetsedwa ndi ESO, yakhala ikuyang'anira kusinthika kwa comet ndi zida monga X-shooter ndi UVES, kujambula "kudzuka" kwake komwe kumayandikira Dzuwa. Ma telescopes ku Canary Islands nawonso athandizira, kulemba kusintha morphology ya mchira.
Mu danga, LASCO coronagraph m'ngalawa SOHO (joint ESA/NASA mission) Yalemba comet pafupi ndi perihelion ngakhale kuti imawala pang'ono. Kuphatikiza apo, zithunzi za CCOR-1 zochokera ku satellite ya GOES-19 zawonetsa njira yake yocheperako pomwe inali kumbali yakutali ya Dzuwa, chitsanzo cha momwe Zida za heliospheric zimatha kuthandizira kusaka kwa comet pansi pa zovuta kuyang'anitsitsa.
Chemistry yapadera: nickel vapor ndi CO2-rich coma
Chimodzi mwazotsatira zochititsa chidwi kwambiri ndi kuzindikira mpweya wa nickel mu chikomokere cha 3I/ATLAS pamtunda waukulu wa heliocentric (≈3,9 AU), popanda zizindikiro zachitsulo zofananira pamwamba pa malire a zida. Chitsanzo chachilendochi chikusonyeza kuti nickel akhoza kutulutsidwa kuchokera kuzinthu zomwe Iwo amathyoka pa kutentha otsika pansi pa cheza cha dzuwa, m'malo mobwera kuchokera ku sublimation mwachindunji kwachitsulo.
Pamene idayandikira, idapezekanso mpweya wa cyanogen (CN).mawonekedwe a comets, ndi zowonera ndi James Webb Space Telescope zimaloza ku chikomokere ndi wolemera mu CO2 pokhudzana ndi madzi, kuwonjezera pa madzi oundana a madzi oundana ndi carbon monoxide. Zonsezi zimapanga chithunzi chamankhwala chovuta chomwe chimathandiza kufananitsa 3I / ATLAS ndi 2I / Borisov ndi nyenyezi za dzuwa ophunzitsidwa bwino.
Mwayi woyezera mchira wa ion kuchokera pazombo zomwe zili panjira
Kafukufuku waposachedwa akupereka njira zothandizira njira za Hera (ESA) ndi kuchokera ku Europa Clipper kuyesa kuwona ma ion kuchokera kumchira wa 3I / ATLAS pawindo lapadera kwambiriPakati pa Okutobala 25 ndi Novembala 1 kwa Hera, komanso kuyambira Okutobala 30 mpaka Novembara 6 kwa Europa Clipper. Ngakhale atapita ku mtunda wa makilomita mamiliyoni kuchokera pakatikati Kuchokera kumchira, kubalalika kwa tinthu tating'onoting'ono tomwe timapanga timadzi tambiri tating'onoting'ono kumatha kuloleza miyeso yothandiza.
Pali zolepheretsa: Hera samanyamula zida zomwe zimapangidwira kuti zigwire ma ion kapena "maginito" owoneka ngati chikomokere, pomwe Europa Clipper ili ndi magnetometer ndi paketi ya plasma yoyenera kuyesa mwayiKomabe, kugwirizanitsa kumakhala kovuta ndipo kumadalira chipinda chochepa chowongolera chomwe chilipo.
Malingaliro odabwitsa komanso mayeso a asidi a perihelion
Monga zidachitika ndi 1I/'OumuamuaPalibe kusowa kwa kutanthauzira kwachilendo. Aganiziridwa kuti 3I/ATLAS ikhoza kukhala chinthu chopanga kapena "Trojan horse"kapena ngati anti-mchira angakhale a dala "braking"Pakalipano, miyeso ya photometric, spectroscopic, ndi morphological ikugwirizana bwino ndi a comet yachilengedwe yomwe imatulutsa fumbi ndi mpweya pansi pa kuyatsa kwapadera ndi momwe zimawonekera.
Perihelion imagwira ntchito ngati kuyesa kotsimikizikaNgati phata lake ndi lophwanyika, kutentha kungathe kuligawanitsa ndi kukulitsa chikomokere chake; ngati sichoncho, Tidzawona ntchito yokhazikika malinga ndi zomwe tikuyembekezera.Zizindikiro zaukadaulo monga zoyendetsa zopanda mphamvu yokoka, magetsi opangira, kapena kutentha kwambiri kwa injini sizinachitike. adanenedwa ndi umboni wamphamvuMu sayansi, kufotokozera kosavuta nthawi zambiri kumakhala kolondola mpaka kutsimikiziridwa mosiyana ndi deta.
Ndi magulu awa a kampeni ochokera ku Europe ndi dziko lonse lapansi, komanso ndi zochitika zomveka bwino - Venus pa Novembara 3, kuyandikira kwambiri padziko lapansi pa Disembala 19 ndi kuyandikira pafupi ndi Jupiter pa Marichi 16, 2026—, 3I/ATLAS imapereka mwayi wapadera woyesa mitundu ya nyenyezi zam'mlengalenga, kukonza njira zowonera ma heliospheric ndi yerekezerani chemistry yake ndi ya Solar System yathu popanda kutenga chilichonse mosasamala chomwe sichimathandizidwa ndi deta.
Ndine wokonda zaukadaulo yemwe wasandutsa zokonda zake za "geek" kukhala ntchito. Ndakhala zaka zoposa 10 za moyo wanga ndikugwiritsa ntchito ukadaulo wotsogola komanso kusewera ndi mitundu yonse yamapulogalamu chifukwa cha chidwi chenicheni. Panopa ndaphunzira luso la pakompyuta komanso masewera a pakompyuta. Izi zili choncho chifukwa kwa zaka zoposa 5 ndakhala ndikulembera mawebusaiti osiyanasiyana pa teknoloji ndi masewera a pakompyuta, ndikupanga nkhani zomwe zimafuna kukupatsani zambiri zomwe mukufunikira m'chinenero chomwe chimamveka kwa aliyense.
Ngati muli ndi mafunso, chidziwitso changa chimachokera ku chilichonse chokhudzana ndi makina opangira Windows komanso Android pama foni am'manja. Ndipo kudzipereka kwanga ndi kwa inu, nthawi zonse ndimakhala wokonzeka kuthera mphindi zochepa ndikukuthandizani kuthetsa mafunso aliwonse omwe mungakhale nawo pa intaneti.
