Pakati pese zvakasikwa kune huwandu hwakawanda hwema comet anogona kukanganisa kutenderera kwedu. Mumwe wavo ndiComet Neowise. Iyo ndeimwe yemakometi anopenya akaonekwa kubva kupasi redu. Izvo zvaigona kuonekwa munaJune 2020 uye zvainakidza.
Muchikamu chino tiri kuzokuudza zvese hunhu, mavambo uye zvido zve comet Neowise.
Mhando huru
Comet Neowise ndeyekukosha kukuru kwesainzi. Zvinogona kutarisirwa kuve nehupamhi hwechipiri, ndiko kuti, kuve nekupenya kwakakwirira, zvichitibvumira kuti tizvione kubva kure pasina kudikanwa kweteresikopu kana maboniboni. Zvekare, iyi kiti kubva ku Oort Cloud. Aya ma data akakosha nekuti makometi aya anowanzo kuve nezvinhu zvakasvibirira kubva kuma nebulae ayo akaumba zuva redu. Saka, dzinopa ruzivo rwakakura kwazvo nezvekwakabva zvinhu zvese.
Saka ndeimwe yemakometi anopenya akapfuura nepasi rose mumakumi emakore apfuura, achitisiyira mukana wekuriona neziso rakashama mukati memwedzi uno uye kupfuura nepasi redu zvakare, pzvakare, mune angangoita makore mazana matanhatu nemazana masere.
Inogona kuonwa kwevhiki yaChikunguru 11-17. Comet Neowise yaionekwa nguva pfupi zuva risati rabuda (kuma6 mangwanani), vachitaura nezveSpain (north hemisphere). Kuti uwane icho, iwe waingofanirwa kutarisa kuchamhembe kwakadziva kumabvazuva, pasi pechikwiriso. Pane yakaderera nhanho, iwe waigona kuona izvo zvishoma zvipingamupinyi pakatarisana. Zvakare, zvaive zvakakosha kuve mune imwe nzvimbo ine zvishoma mwenje kusvibiswa kuti ugone kukoshesa denga rese mushe.
Nguva yepedyo yaakasvika paNyika yaive musi waChikunguru 23, uye yaive makiromita anosvika mamirioni 103 padhuze nepasi pakukura 4. Iyo daro yakakura zvakakwana zvekuti hapana njodzi yekukanganisa, saka hapana chikonzero chekushushikana nezvechiitiko ichi. Nekudaro, kunyangwe zuva repedyo pasi pano raive Chikunguru 23, Comet Neowise yaionekwa neziso rakashama, uye simba rayo rakaramba riri padanho rechipiri kusvika Chitatu, Chikunguru 2.
Kwakatangira Comet Neowise
Mutungamiriri yakawanikwa munaKurume 27, 2020 mune infrared mifananidzo. Yakawanikwa panguva yeProjekti -Pasi Zvinhu zvepurojekiti neNASA's Wide-Field Infrared Survey Explorer (WISE) space teresikopu. Iyi teresikopu yepasi yakakwanisa kuona chinhu chakakura gumi neshanu chaimiririra imwe, 17 'muhukuru hwakakura. Zvishoma nezvishoma vamwe vacherechedzi vakakwanisa kusimbisa chiitiko chayo senge comet, kuyera sadza rakanyorovera kusvika 0.8 'dhayamita uye muswe makumi maviri' 'pakureba.
Comet C / 2020 F3 (NEOWISE) ine quasi-parabolic orbit saka haisi nyowani, ndima yayo yapfuura yaive makore zviuru zvitatu apfuura. Yayo inotevera perihelion ichave muna Chikunguru 3.000, 3 chinhambwe che 2020 AU chete kubva kuSuva, uye nzira yayo yepedyo pasi pano. mazuva mashoma gare gare muna Chikunguru 23, 2020 pa0.69 AU kubva pasi redu.
Yakanga iine kuwedzera kusinganzwisisike nekupenya mukujeka kune izvo zvatakajaira mune mamwe ma comet. Iyo yakajeka curve yakadzikama mukati memwedzi waMay nemhedziso yakakura parameter ye m0 = 7. Aya maitiro anowirirana nenucleus ingangoita makiromita maviri muhupamhi uye chiitiko chepamusoro chiitiko che n = 5. Iwe unofanirwa kuziva kuti pane indekisi inoratidzira njodzi yekukanganisa kometi panguva yayo yekufamba. Mune ino kesi, Comet Neowise ane yakaenzana kuora njodzi inoenderana neBortle yekupona muganho.
Comet Neowise Nguva
Mumazuva gumi ekutanga aJune, kupenya kweComet Neowise kwakaramba kuchikura, kuchisvika padanho 10. Zvinoenderana neyakaitika kubva Chivabvu, kupenya kwayo kwaive hafu yakaderera pane zvaitarisirwa, kunyangwe izvi zvingave zvichikonzerwa nekukwira kwakadzika kwevanoona kumaodzanyemba. Kana tikadzidza kukura kwecoma yakacherechedzwa, iyo zvakare yakaderera mukati memazuva iwayo uye condensation yakawedzera. Zvese izvi zvakasimbisa kuti fungidziro dzakakanganiswa nekuderera kwakadzika uye kwayedza.
Neraki, pakati paJune 22 na28, kometi yakasvika isingasviki 2 ° kubva kuzuva, ichipinda mumunda weLASCO-C3 kamera yeSOHO nzvimbo teresikopu, iyi teresikopu yakatsaurirwa kucherechedza mamiriro ekunze eSuva ane macoronagraphy avanoviga. mwenje wakananga wezuva dhisiki uchibvumira kunyoresa, pamusoro pezvekuburitswa kweZuva, zvinhu zvinojeka zvinozviswededza angularly sezvazviri mamiriro emakometi mazhinji.
Naizvozvo, isu takakwanisa kucherechedza munzvimbo iyo comet yakasvika perihelion mune yakanaka mamiriro, kugadzira muswe weguruva uye muswe weion, uye uchitibvumidza kuyera kupenya kwavo. Yakawedzera ukuru hwekujeka kubva ku2 kusvika ku3 mumazuva matanhatu. Izvi zvakasimbisa kuti zvakagara mukati meyakafanotaurwa mwenje curve. Pakazosvika Chikunguru 6, 11, kometi inogona kunge ichinyatso kucherechedzwa neziso rakashama pazasi penyeredzi Capella del Auriga, ichiri panguva yemangwanani emangwanani asi ichikwirira kupfuura mazuva apfuura.
Kite ichienda kure
Mushure mekuswedera padhuze nepasi, muna Chikunguru 23, chinhambwe kubva kuUnited States chaive 0,69. Panyika yedu, kupenya kwekometi kwakaramba kuchiderera kudzamara kwave kusingaonekwe kune ziso rakashama pahukuru hwe4.5 kupenya. Kunyangwe ichionekwa kuburikidza nemabhainokura, zvisinei nemwenje wemwedzi, muswe wayo waive uchiri wakajeka uye uchinyatsoonekwa. Kukoma kwake kwakaramba kuri mukati memakona angangoita maminetsi masere (mazana matatu emakiromita zviuru mazana matatu), uye condensation yakaenderera kusvika padanho 6 uye ichiri yakasimba kwazvo. Kureba kwemuswe wakacherechedzwa nema binoculars kwaive 3 degrees.
Sezvauri kuona, kometi iyi yaive imwe yeanonyanya kuzivikanwa uye anoonekwa nenyanzvi nevateereri. Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve comet Neowise nehunhu hwayo.
