Oumuamua - interstellar cigar

"Vatorwa vasvika. Vatouya! - zvikumbiro zvakadaro zvakatsvaira munhau neInternet pakupera kwegore rapfuura. Izvi zvakakonzerwa neasteroid Oumuamua, iyo isina kungobva kunze kwesolar system, asiwo yakanga ine chimiro chinoshamisa chakareba. Zvakafanana nemazano edu nezve extraterrestrial base ship.

 akadaro, aigara achitaurwa zvakanyanya munhau. --.

Tinofanira kufungidzira zvakawanda nezveUFOs? Aihwa. Ndiwo matangiro azvakaita. Pakave nezvinyorwa zvine zano rekuita kana wasangana nevatorwa, vachipihwa vavariro dzavo. Vamwe, zvakare, vakaratidza pfungwa yokuti "ivo" vanongobhururuka uye havaiti hanya nesu, sezvakaitika mune imwe yenyaya dzaLem pamusoro pePirks mutyairi.

Mukukudzwa kwake, masayendisiti akatumidza chinhu 1I/2017 U1. omuamua uye vakanyara vakataura kuti inogona kunge isiri mhizha yevatorwa, asi chaive chinhu chinonakidza zvakadaro nekuti yaive yekutanga kucherechedzwa interstellar asteroid.

Organic "cocoon"

Kumubvunzo wekuti "Ichi ichikepe chemuchadenga here?" asi zvakatotambudza varume vesainzi.

 Purofesa Alan Fitzsimmons weQueen's University Belfast, uyo akatungamira chirongwa chekutsvagisa chemuenzi anonakidza kubva kune nyeredzi, akadaro pamusangano wevatori venhau.

Asteroid iri pedyo nePasi 8 Gumiguru 2017 Ipapo ndipo pakawana teresikopu yePan-STARRS1. Masayendisiti akashandura maturusi avo uye kutarisa kune chinhu chinokatyamadza. Iyo purojekiti yakafunga kutarisa kana 'Oumuamua inoburitsa mafungu eredhiyo. Nekudaro, ongororo dzakaitwa nerubatsiro rwemakomputa makuru hadzina kuratidza chero chinhu cherudzi urwu.

Saka haisi ngarava. Masayendisiti ainetseka kana taive tichibata nekometi kana kuti asteroid. Nekuda kwekutsvaga kwakasimba, zvakaonekwa kuti chinhu chine chimiro chakareba kwazvo, approx. 200 20 x m, uye reflectivity (albedo) zvichida 0,04. Nguva yekutenderera ndeye 7-8 maawa, iyo inotangwa neakasiyana mafotometric kuona. Zvakare, ruvara rwayo rwakasviba, nemumvuri wemutsvuku, wakafanana nemuvara wemamwe matumbi maduku munzvimbo dzekunze dzezuva. Saka, zvinoita sekunge mune mamwe mapuraneti masisitimu mune zvinhu zvakafanana kune izvo zvinozivikanwa kubva.

Kuti vawane ruzivo rwekuona pamusoro peasteroid, boka rekutsvagisa pasi rese rakashandisa teresikopu hombe se4,2-mita William Herschel Telescope (WHT) pachitsuwa cheLa Palma uye 8,2-mita Very Large Telescope (VLT) muChile, ye European Southern Observatory (ESO).

Maererano nevatsvakurudzi, iyo ice core inogona kuvhara organic protective layer kubva kune solar cosmic rays inenge mamita mashanu. ndiani anoziva chii! 

Mhuka yeOumuamua trajectory: 

Oumuamua akauya kwatiri kubva kudivi renyeredzi Vega (boka renyeredzi Lutes), iyo yatinogona kuona zviri nyore neziso rakashama, nokuti ndiyo imwe yenyeredzi dzinopenya zvikuru mudenga reusiku. Nekudaro, masayendisiti anotenda kuti haisi kubva kuVega system. Inofungidzirwa kuti "yakatangwa" munzvimbo yepakati semugumisiro wemaitiro ekuumbwa kweimwe rudzi rwemapuraneti. Zvadaro pane kudhumhana kwakawanda, uye zvidimbu zvinowana simba guru. 'Oumuamua anogona kunge ari mumwe wavo. Inogona kunge ichifamba munzvimbo yeinterstellar. mamiriyoni emakoreuye mavambo chaiwoiwo haazivikanwi. Vatsvakurudzi vakaverenga kuti kangani zvinhu izvi zvinobhururuka kuburikidza nesolar system nyaya imwe pagore.

Saka hapana sensation. Kunyanya, iyo nzira, asi haina kupinda mukati mekupokana kwekufunga nezve "Vatorwa". Zvakanaka, sekufungidzira kuri pamusoro pamusoro pechimiro cheOumuamua chinoratidza, kune inodzivirira organic layer kumashure kwayo. ice mukati. Ice, zvichida mvura? Kana zvakadaro, saka imvura kubva kure, isingazivikanwe nyeredzi system. Saka mvura iri kwese kwese muchadenga? Uye kana paine mvura, zvino ...

Handifungi kuti panoda imwe tsananguro.
