Tlhaloso e Khutšoanyane ea Astrophysics
Astrophysics ke lekala le khahlang le le pharaletseng la bolepi ba linaleli le sebelisang melao-motheo ea fisiks le k'hemistri ho utloisisa tlhaho ea libopuoa tsa leholimo le bokahohle ka kakaretso. E teba kutloisisong ea linaleli, lipolanete, lihlopha tsa linaleli, masoba a matšo, linaleli tsa neutron, le mahlaseli a bokahohle a microwave, har'a liketsahalo tse ling tse ngata tsa leholimo. Jwalo ka lefapha la thuto e fapaneng, astrophysics e kopanya likheo lipakeng tsa libaka tse fapaneng tsa saense ho araba tse ling tsa lipotso tse tebileng ka boteng ba rona le bokahohle.
Tšimoloho le Tsoelo-pele ea Histori
Tšimoloho ea astrophysics e ka lateloa morao ho ea lichabeng tsa boholo-holo, moo batho ba qalileng ho shebella lintho tsa leholimo ka mokhoa o hlophisehileng. Menehelo ea pele e ne e tsoa litsong tse fapaneng, ho kenyeletsoa Bagerike, Baegepeta, Machaena le MaMesopotamia, ba ileng ba hlahisa mehlala ea pele ea maholimo 'me ba batla ho hlalosa metsamao ea linaleli le lipolanete.
Leha ho le jwalo, astrophysics ya sejwalejwale e ile ya qala ho hlaha nakong ya Renaissance. Nicolaus Copernicus o ile a sisinya mohlala wa heliocentric wa tsamaiso ya letsatsi, a phephetsa mohlala wa geocentric wa kgale. Tshebediso ya Galileo Galilei ya telescope mathoasong a lekgolo la bo17 la dilemo e senotse dintlha tse mabapi le dibopuwa tsa lehodimo tse neng di sa bonoe pele, tse kang dikgwedi tsa Jupiter le mekhahlelo ya Venus. Johannes Kepler le Isaac Newton ba ile ba fetola kutlwisiso ya rona ya bokahohle ka melao ya motsamao wa dipolanete le molao wa matla a khoheli a bokahohle, ka ho latellana.
Mehopolo ea Motheo ho Astrophysics
Fisiks ea linaleli e akaretsa likhopolo tse fapaneng tsa motheo, e 'ngoe le e 'ngoe e tlatsetsa kutloisisong ea rona e pharaletseng ea bokahohle:
1. Sekhahla sa Elektromakenete
Litsebi tsa linaleli li itšetleha ka sekala sa motlakase ho bokella tlhahisoleseling mabapi le lintho tsa leholimo. Sekala sena se kenyelletsa mahlaseli a gamma, mahlaseli a X, leseli la ultraviolet, leseli le bonahalang, mahlaseli a infrared, li-microwave le maqhubu a seea-le-moea. Mefuta e fapaneng ea sekala sena e senola litšobotsi le lits'ebetso tse fapaneng tse etsahalang linthong tsa leholimo. Mohlala, mesi ea X-ray e ka bontša liketsahalo tse nang le matla a mangata joalo ka masoba a matšo, ha leseli le bonahalang le ka re tsebisa ka mocheso le sebopeho sa linaleli.
2. Phetoho ea Linaleli
Ho iphetola ha linaleli ho hlalosa potoloho ea bophelo ba linaleli, ho tloha ho thehoeng ha tsona marung a limolek'hule ho isa pheletsong ea tsona ea ho qetela. Linaleli li tsoalloa libakeng tsa sebaka moo khase le lerōle li bokellanang le ho putlama tlas'a matla a khoheli. Ha nako e ntse e ea, ho kopana ha nyutlelie hoa hotetsa ka hare, ho leka-lekanya ho huloa ha matla a khoheli ka hare le khatello ea mocheso ea kantle. Ho latela boima ba tsona, linaleli li ka felisa bophelo ba tsona e le li-dwarf tse tšoeu, linaleli tsa neutron, kapa masoba a matšo.
3. Thuto ea bokahohle
Thuto ea bokahohle ke karoloana e ithutang sebopeho le nalane e kholo ea bokahohle. E kenyelletsa lipatlisiso tsa tšimoloho ea bokahohle, katoloso ea bona, le qetello ea bona e ka bang teng. Khopolo-taba ea Big Bang, e tšehetsoang ke bopaki ba ho shebella joalo ka mahlaseli a morao a microwave a bokahohle le phetoho e khubelu ea lihlopha tsa linaleli, ke mohlala o atileng o hlalosang qalo le phetoho ea bokahohle.
4. Kakaretso ea Kamano
Khopolo-taba ea Albert Einstein ea kamano e akaretsang, e phatlalalitsoeng ka 1915, e fetotse kutloisiso ea rona ea matla a khoheli. Ho e-na le ho talima matla a khoheli e le matla a pakeng tsa bongata, kamano e akaretsang e a hlalosa e le ho kobeha ha nako ea sebaka ho bakoang ke boima le matla. Khopolo-taba ena ea bohlokoa bakeng sa ho hlalosa liketsahalo tse kang ho kobeha ha leseli ho potoloha lintho tse kholo (lensing ea matla a khoheli) le potoloho e nepahetseng ea lipolanete.
Lisebelisoa le Mekhoa ea Sejoale-joale ea Bolepi ba Linaleli
Tsoelo-pele ea theknoloji e lumelletse litsebi tsa linaleli ho etsa mehato e meholo ho sibolleng liphiri tsa bokahohle. Tsena ke lisebelisoa le mekhoa ea bohlokoa:
1. Libonela-hōle
Dithelesekoupo tsa mahlo e bile tsa motheo ho tloha mehleng ea Galileo, empa astrophysics ea sejoale-joale e sebelisa lithelesekoupo ho pholletsa le spectrum eohle ea motlakase. Mohlala, Hubble Space Telescope e shebella libakeng tsa ultraviolet, tse bonahalang, le tse haufi le infrared, ha Chandra X-ray Observatory e shebane le mesi e ntšang mahlaseli a X-ray. Dithelesekoupo tsa seea-le-moea, joalo ka tse etsang Very Large Array (VLA), li lemoha maqhubu a seea-le-moea mehloling ea linaleli.
2. Spectroskopia
Spectroscopy e kenyelletsa ho sekaseka lesedi le tswang dinthong tsa lehodimo ho fumana sebopeho sa tsona, mocheso, bongata le motsamao. Ka ho ithuta mela ya spectral, ditsebi tsa astrophysicists di ka fumana boteng ba dielemente le di-isotope tse itseng, ho fana ka temohisiso mabapi le thepa ya mmele le ya dikhemikhale ya dibopuwa tsa dinaledi.
3. Liketsiso tsa Khomphutha
Diketsiso tse tsamaiswang dikhomphutheng tse kgolo di bapala karolo ya bohlokwa ho astrophysics, e leng se dumellang bafuputsi ho etsa mohlala wa diketsahalo tse rarahaneng tse kang ho thehwa ha dihlopha tsa dinaledi, ho kopanngwa ha masoba a matsho le supernovae. Diketsiso tsena di thusa bo-rasaense ho leka dikgopolo le ho hlalosa tlhahisoleseding ya ho shebella, ho fana ka laboratori ya sebele bakeng sa ho hlahloba bokahohle.
Lintho tse sibolotsoeng le lipatlisiso tsa morao tjena
Lilemo tse mashome tsa morao tjena li bone lintho tse sibolotsoeng tse hlollang tse atolositseng kutloisiso ea rona ea bokahohle:
1. Lipolanete tse tsoang linaheng tse ling
Ho sibolloa ha lipolanete tse phelang kantle ho lefatše—lipolanete tse potolohang linaleli ka ntle ho tsamaiso ea rona ea letsatsi—ho fetotse kutloisiso ea rona ea litsamaiso tsa lipolanete. Ho fihlela joale, lipolanete tse likete li tiisitsoe, tse ngata li na le boholo le lits'ebetso tse fapaneng. Mesebetsi e kang Kepler ea NASA le TESS (Transiting Exoplanet Survey Satellite) e bile le thuso ho khetholleng mafatše ana, ao a mang a 'ona a leng libakeng tse ka pheloang tsa linaleli tsa tsona, moo metsi a metsi a ka bang teng.
2. Maqhubu a Matla a Khoheli
Ka 2015, Laser Interferometer Gravitational-Wave Observatory (LIGO) e entse nalane ka ho lemoha maqhubu a khoheli, maqhubu a sebaka se bakiloeng ke ho kopana ha masoba a mabeli a matšo. Tšibollo ena e butse fensetere e ncha ea ho shebella bokahohle, e lumellang litsebi tsa linaleli ho ithuta liketsahalo tsa bokahohle tse sa bonahaleng ka ho shebella ka mekhoa ea setso ea motlakase.
3. Dintho Tse Lefifi le Matla a Lefifi
Phuputso ea linaleli e ntse e tsoela pele ho batlisisa taba e makatsang e lefifi le matla a lefifi, tseo hammoho li etsang hoo e ka bang 95% ea matla a mangata a bokahohle. Leha li sa ntše leseli, litlamorao tsa tsona tsa matla a khoheli lia bonahala, li susumetsa ho potoloha ha lihlopha tsa linaleli le sekhahla sa katoloso ea bokahohle. Ho utloisisa likarolo tsena e ntse e le e 'ngoe ea meeli e thata le e thabisang ka ho fetisisa ho astrophysics.
fihlela qeto e
Fisiks ea linaleli e eme moo ho kopanang bohelehele le ho sibolla lintho, e susumetsoa ke takatso ea ho utloisisa melao-motheo le mekhoa ea motheo ea bokahohle. Ho tloha linthong tse nyenyane tsa likamano tsa athomo ho ea ho moralo o moholo oa cosmology, tšimo ena e akaretsa mefuta e fapaneng ea liketsahalo. Ka tsoelo-pele e 'ngoe le e 'ngoe ea theknoloji le tsoelo-pele ea khopolo-taba, astrophysics e re atametsa haufi le ho araba lipotso tse tebileng tse 'nileng tsa khahla batho ka lilemo tse likete. Ha re ntse re tsoela pele ho hlahloba bokahohle, ho phehella tsebo ea astrophysics ho tšepisa ho senola ho eketsehileng ka mofuta oa boteng ba rona le bokahohle bo boholo boo re phelang ho bona.
