<prompt> Fingqa isihloko: Abacwaningi baveze imfihlakalo yombala ofihlekile kaMercury. Bathi ukuchitheka kancane kancane kwekhabhoni okuvela ezinkanyezini ezinomsila ezidlulayo kuye kwenza iMercury yaba mnyama izigidigidi zeminyaka. Ixazulula imfihlakalo yombala ongavamile kaMercury - oye wadida ososayensi. Bathi ukushabalala njalo kwekhabhoni okuvela ezinkanyezini ezinomsila ezidlulayo kuye kwaveza kancane kancane iMercury ngengubo emnyama engabonakali phakathi neminyaka eyizigidigidi. Uthuli lwezinkanyezi ezinomsila lwakhiwe cishe ngo - 25 ekhulwini wekhabhoni ngesisindo, ngakho iMercury ibingachayeka ekuhlaselweni njalo kwekhabhoni evela kulezi zinkanyezi ezinomsila eziwohlokayo. Besebenzisa imodeli yokunikeza umthelela nesilinganiso esaziwayo sokugeleza kwama - micrometeorite eMercury, abacwaningi babala basikisela ukuthi ngemva kwezigidigidi zeminyaka yokushaywa, ubuso beMercury kufanele bube yikhabhoni engamaphesenti amathathu kuya kwayisithupha. Sekuyisikhathi eside kucatshangwa ukuthi kunento eyimfihlakalo emnyama ebangela ukuba iMercury ibe ne-reflectance ephansi, kusho uMegan Bruck Syal, umcwaningi ongudokotela eLawrence Livermore National Laboratory owenza lolu cwaningo ngesikhathi esengumfundi ophothule iziqu eBrown University. Into eyodwa eyayingakacatshangelwa ukuthi iMercury ihlakazwa izinto eziningi ezitholakala emagumbini omhlaba. Ngokwesilinganiso, iMercury imnyama kakhulu kunomakhelwane wayo oseduze ongenawo umoya, iNyanga yethu. Imizimba engenamoya iyaziwa ukuthi iba mnyama ngenxa yokushayisana kwama-micrometeorite nokushayisana komoya welanga, izinqubo ezakha ungqimba oluncane lwezinhlayiya ze-nanoparticles ezimnyama zensimbi ebusweni. Kodwa imininingwane ye-spectral evela kuMercury ibonisa ukuthi ubuso bayo buqukethe insimbi encane kakhulu yama-nanophase, ngokuqinisekile ayanele ukuba ichaze ukubukeka kwayo okungaqondakali. Lapho izinkanyezi ezinomsila zisondela eduze kukaMercury eduze nelanga, ngokuvamile ziqala ukuhlukana. Uthuli lwezinkanyezi ezinomsila lwakhiwe cishe ngo - 25 ekhulwini wekhabhoni ngesisindo, ngakho iMercury ibingachayeka ekuhlaselweni njalo kwekhabhoni evela kulezi zinkanyezi ezinomsila eziwohlokayo. Esebenzisa imodeli yokulethwa kokushayisana nokulinganiselwa okwaziwayo kokugeleza kwe-micrometeorite eMercury, uBruck Syal wakwazi ukulinganisa ukuthi impahla yezinkanyezi ezinomsila izoshaya kangaki iMercury, ukuthi kungakanani ikhabhoni...  <response>: Ukukhukhuleka kwekhabhoni evela ezinkanyezini ezinomsila ezidlulayo kwenze iMercury yaba mnyama. Ubuso beMercury bunamakhabhoni aphakathi kwamaphesenti amathathu kuya kwayisithupha. Inikeze iplanethi ukubukeka okumnyama.
