I-Astronomy

Izibikezelo Zesikhathi Esizayo Zocwaningo Lwezinkanyezi I-Astronomy, enye yezifundo zesayensi ezindala kakhulu, iveze izinto ezimangalisayo mayelana nokuba khona kanye nesakhiwo sendawo yonke. Emashumini eminyaka amuva nje, intuthuko yezobuchwepheshe iye yasheshisa ijubane lokutholwa kwezinkanyezi futhi yasiza ekuxazululeni izimfihlakalo mayelana nendawo yonke. Besebenzisa ama-telescope athuthukile, amasathelayithi, namakhompyutha, ososayensi manje sebekwazi ukuhlola okwengeziwe… Funda kabanzi

Umlando Wokutholakala Kweplanethi iVenus Iplanethi iVenus, evame ukubizwa ngokuthi "inkanyezi yokusa" noma "inkanyezi yakusihlwa," ibilokhu idonsa isintu isikhathi eside. Ngokukhanya kwayo okukhanyayo esibhakabhakeni sasebusuku, ibilokhu iyisihloko sokubonwa kwesayensi kanye nengxoxo iminyaka eyizinkulungwane.

Umlando Wokutholakala KweVenus Umlando wokutholakala kweVenus uhambo olude oluchaza izimangaliso zezinkanyezi, kusukela ezikhathini zasendulo kuya enkathini yanamuhla. Njengento ekhanyayo yasezulwini ngemva kweLanga neNyanga, iVenus idonsele ukunaka kwabantu iminyaka eyizinkulungwane. Lesi sihloko sizohlola inqubo yokutholwa kanye nokuhlolwa kwesayensi kwale planethi kusukela ekuqaleni kwempucuko kuya ekutadisheni... Funda kabanzi

Inkolelo-mbono yokukhuphuka kwe-cosmic ingenye yemibono eminingi yesayensi ehlose ukuchaza omunye wemibuzo emikhulu ku-cosmology: indawo yethu enkulu yathuthuka kanjani kusukela esimweni sokuqala esincane nesinzima kangaka? Yethulwe yisazi sesayensi u-Alan Guth ngo-1980, lo mqondo usize ekuxazululeni amaphazili amaningana… Funda kabanzi

Indlela Ama-Meteorite Athinta Ngayo Umhlaba Ama-Meteorite yizinto zasezulwini ezivela emkhathini wangaphandle futhi zifinyelele ebusweni boMhlaba ngemva kokudlula emkhathini. Nakuba ama-meteorite amaningi emancane futhi asha lapho engena emkhathini, amanye amakhulu angasinda futhi abe nomthelela omkhulu eMhlabeni. Lesi sihloko sizochaza ukuthi ama-meteorite athinta kanjani uMhlaba ngezindlela ezahlukene, kusukela... Funda kabanzi

Ziyini Izimbobo Ezimnyama Futhi Zisebenza Kanjani? Izimbobo Ezimnyama zingenye yezinto ezithakazelisa kakhulu neziyimfihlakalo endaweni yonke. Lo mqondo waqala ukuphakanyiswa yisazi sezinkanyezi, isazi semfundiso yenkolo, kanye nesazi sezibalo uKarl Schwarzschild ngo-1916, ngemuva nje kokuba u-Albert Einstein eshicilele umbono wakhe ojwayelekile wokuhlobana kwezinto. Nakuba kubonakala sengathi kukude kakhulu nokuphila kwethu kwansuku zonke, ukuqonda izimbobo ezimnyama… Funda kabanzi

Amaqiniso Athakazelisayo NgeJupiter IJupiter iyiplanethi enkulu kunazo zonke ohlelweni lwethu lwelanga futhi inezici eziningana ezihlukile ezenza kube yisihloko esithakazelisayo socwaningo nengxoxo phakathi kososayensi nabathandi bezinkanyezi. Kulesi sihloko, sizohlola amaqiniso ahlukahlukene athakazelisayo ngeJupiter, kusukela ngobukhulu bayo nokwakheka kwayo kuya ezimweni zayo zasemkhathini kanye nezinyanga ezithakazelisayo. … Funda kabanzi

Indlela Yokubala Amabanga Phakathi Kwamaplanethi Ukubala amabanga phakathi kwamaplanethi ohlelweni lwethu lwelanga kudinga ulwazi oluyisisekelo lwezinkanyezi kanye nokuqonda imiqondo eminingana kanye nezindlela zokubala. Lesi sihloko sizoxoxa ngezindlela ezahlukene zokubala amabanga phakathi kwamaplanethi, sisebenzisa izindlela ezilula zabaqalayo kanye nezindlela eziyinkimbinkimbi kakhulu kulabo... Funda kabanzi

Ukuqonda Ukufiphala Kwenyanga Nokwelanga: Ukufiphala kwenyanga kungenye yezinto zemvelo ezimangalisa kakhulu, ezivame ukukhanga labo abazibonayo.

Umsebenzi Weziphuphutheki Zemvelo Zeplanethi Isiphuphutheki semvelo, esivame ukwaziwa ngokuthi inyanga, siyinto yezinkanyezi ejikeleza iplanethi noma omunye umzimba wasezulwini. INyanga, ejikeleza uMhlaba, iyisibonelo esaziwa kakhulu sesiphuphutheki semvelo. Kodwa-ke, ukuba khona kweziphuphutheki zemvelo akugcini eMhlabeni; amaplanethi amaningi ohlelweni lwethu lwelanga, kanye namaplanethi angaphandle kwesimiso sethu selanga, … Funda kabanzi
