Riaan Ucwaningo olushicilelwe kuleli sonto lubonisa ukuphazamiseka okwandayo kwezithombe zezinkanyezi ezibangelwa amasathelayithi ezentengiselwano, okwengeza ukukhathazeka ngemiphumela yemboni yasemkhathini ezimele kwezesayensi.
Besebenzisa ama-algorithms okufunda okujulile ukuskena izithombe zomlando ezithathwe i-Hubble Space Telescope phakathi kuka-2002 no-2021, abacwaningi bathola amaphesenti angu-2.7 ± 0.2 ezithombe ezinesikhathi sokuchayeka esivamile semizuzu engu-11 equkethe okungenani umzila wesathelayithi owodwa.
Kodwa phakathi naleso sikhathi, amathuba okuba i-photobomb ye-space hardware akhule kakhulu. Isilinganiso sengxenye yesathelayithi ye-Advanced Camera Survey/Wide-Field Channel (ACS/WFC) ethintekile inyuke isuka kumaphesenti angu-2.8 ± 0.2 ngo-2002-2005 yaya kumaphesenti angu-4.3 ± 0.4 ngo-2018-2021, isibonelo.
Abacwaningi bathole ukuthi ingxenye yezithombe ezithintekile incike kusayizi wenkundla yokubuka, isikhathi sokuchayeka, isihlungi nokukhomba. “Ngenxa yokwanda kwenani lamasathelayithi okwenziwa ahlelwayo njengamanje, ingxenye yezithombe zeHubble Space Telescope enqanyulwa amasathelayithi izokhula eminyakeni eyishumi ezayo futhi izodinga ukucwaninga okwengeziwe nokuqapha,” kusho ucwaningo. eyanyatheliswa kuyi-Nature Astronomy.
Umsebenzi wawuholwa nguSandor Kruk, umcwaningi wangemva kokuthola iziqu zobudokotela eMax Planck Institute for Extraterrestrial Physics.
Ekhuluma no New York TimesuJonathan McDowell, isazi sezinkanyezi e-Harvard-Smithsonian Center for Astrophysics, uthe imiphumela imayelana.
“Sizobe siphila nale nkinga. Futhi isayensi yezinkanyezi izoba nomthelela. Kuzoba nesayensi engeke yenziwe. Kuzoba nesayensi ebiza kakhulu ukuyenza. Kuzoba nezinto esigejayo,” kusho.
Ngokuvumelana ne Isayensi yaseMelika, Umlaza wesathelayithi ye-inthanethi ye-Starlink ye-SpaceX ungomunye wabathintekayo uma kuziwa ekuqapheliseni okusekelwe phansi. I-Zwicky Transient Facility yaseCalifornia ibheka ukuqhuma kwe-supernova okuvela ezinkanyezini ezifayo nama-asteroids adlula eduze noMhlaba ngokuskena isibhakabhaka njalo ezinsukwini ezimbili ukuze kubonakale ukukhanya kwesikhashana noma ukuvela okungazelelwe kwezinto ezihlala zibonakala isikhashana nje.
NgoJanuwari, ukushicilelwa kubikiwe ukuthi ukubuyekezwa kwedatha ebuyela emuva ku-2019, unyaka lapho i-SpaceX yaqala khona ukwethula i-Starlink, yabonisa ukuthi imibono yesibonakude esinemigqa kungenzeka ibe umphumela wokuphazanyiswa kwesathelayithi. ®
