<prompt> Fingqa isihloko: CNN Njengoba amaplanethi ehamba, uMercury akatholi uthando oluningi. Abantu bachitha isikhathi esiningi ku-Google befuna umculi weQueen uFreddy Mercury kuneplanethi enguMercury... futhi uFreddy ubengekho cishe ingxenye yekhulu leminyaka. Ngisho ne-NASA ayichithi isikhathi esiningi lapho, okwenza kube iplanethi engaphakathi engahlolisiswanga kakhulu esimisweni sonozungezilanga. Kodwa sekuyisikhathi eside ososayensi bedidekile ngombuzo owodwa: Kungani le nto emnyama kangaka? Uma iqhathaniswa nenyanga yethu, enobukhulu obucishe bufane, iMercury ikhipha ukukhanya okuncane kakhulu. Ososayensi baseLawrence Livermore National Laboratory, eBrown University nasePlanetary Sciences Institute bathi kungenzeka ukuthi bayitholile impendulo: Iye yagqokwa yaba mnyama ngokuphumelelayo, ngokwamazwi kaMegan Bruck Syal, umcwaningi owayesanda kuthweswa iziqu zobudokotela eLawrence Livermore. Eminyakeni eminingi edlule, abacwaningi bathi ephepheni elishicilelwe ngoMsombuluko kuyi - Nature Geoscience, ama - meteorite amancane avela ezinkanyezini ezinomsila ezinekhabhoni eningi kungenzeka aye anikela ngekhabhoni enombala omnyama ngokwanele ukuze anciphise inani lokukhanya okuboniswayo. Izingcezu zibonakala zihlangana: Kunothuli lwekhabhoni oluningi olukhishwa izinkanyezi ezinomsila eziseduze nelanga, lapho iMercury izungeza khona - cishe izikhathi ezingu - 50 kuMercury uma kuqhathaniswa nenyanga yethu, kusho abacwaningi. Futhi ukuhlolwa kusetshenziswa isibhamu esikhulu se - NASA esenzelwe ukulingisa ukushayisana kwamaplanethi ngezinga elincane kubonakala kubonisa ukuthi lemfundiso inengqondo, kusho abalobi. UPeter Schultz, onguprofesa wezesayensi yokwakheka komhlaba eBrown University, wathi: Sibonisa ukuthi i-carbon isebenza njengento efihlekile eyenza izinto zibe mnyama. Ngokombono wokuhlaziywa kwe-spectral, kunjengopende ongabonakali.  <response>: Abacwaningi bathi iMercury yapendwa yaba mnyama yizigidi zeminyaka yama - micrometeorite. Lolu cwaningo lungase luxazulule imfihlakalo yokuthi kungani iplanethi ibonakala imnyama kangaka.
