Latest Discoveries in the Field of Astronomy
A cikin babban sararin samaniya mai faɗi da kuma faɗaɗawa, masana ilmin taurari suna ci gaba da leƙawa cikin abin da ba a sani ba, suna bayyana sirrin sararin samaniya da yawa. Fannin ilmin taurari yana ci gaba da bunƙasa, wanda ci gaban fasaha, sabbin hanyoyin bincike, da haɗin gwiwa tsakanin ƙasashen duniya ke ƙaruwa. Shekarun da suka gabata sun kasance masu ban sha'awa musamman, waɗanda aka nuna su da sabbin abubuwan da suka zurfafa fahimtarmu game da sararin samaniya da kuma tura mu zuwa ga sabbin iyakoki. Wannan labarin ya bincika wasu daga cikin sabbin abubuwa mafi mahimmanci a fannin ilmin taurari.
1. The First Image of a Black Hole
Wani babban nasara da ta kama duniya ta faru ne a watan Afrilun 2019, lokacin da haɗin gwiwar Event Horizon Telescope (EHT) suka fitar da hoton farko na wani ramin baƙi. Wannan babban ramin baƙi yana tsakiyar tauraron taurarin M87, kimanin shekaru miliyan 55 na haske daga Duniya. Hoton, da'ira mai duhu da aka lulluɓe da zoben haske mai haske, ya tabbatar da hasashen ka'idoji na shekaru da yawa ta hanyar nuna sararin taron - wurin da babu abin da zai iya tserewa, har ma da haske.
Wannan gagarumin ci gaba ya buƙaci haɗakar ƙoƙari daga cibiyoyin lura da rediyo guda takwas a faɗin duniya, inda aka ƙirƙiri na'urar hangen nesa mai girman duniya yadda ya kamata. Hoton ya ba da bayanai masu mahimmanci game da kimiyyar lissafi ta ramin baƙi, halayen abu a ƙarƙashin yanayi mai tsanani, da filayen nauyi, wanda hakan ya ƙara ƙarfafa ka'idar Einstein ta dangantaka ta gabaɗaya.
2. Detection of Phosphine on Venus
A watan Satumba na shekarar 2020, masana ilmin taurari sun sanar da gano iskar phosphine a cikin yanayin Venus. Phosphine, kwayar halitta da ta ƙunshi atom ɗaya na phosphorus da atom uku na hydrogen, tana da mahimmanci saboda, a Duniya, tana da alaƙa da ayyukan halittu, musamman waɗanda ke cikin yanayin rashin iskar oxygen. An gano wannan binciken ta amfani da na'urar hangen nesa ta James Clerk Maxwell (JCMT) a Hawaii da kuma Atacama Large Millimeter/submillimeter Array (ALMA) a Chile.
Duk da cewa kasancewar phosphine a kan Venus ba lallai bane ya nuna rai, yana haifar da tambayoyi masu gamsarwa game da yiwuwar rayuwa ta ƙwayoyin cuta a cikin yanayi mai tsauri da acidic na Venus. An shirya ayyukan ci gaba da lura don ƙarin bincika wannan yuwuwar mai ban sha'awa, mai yiwuwa sake rubuta fahimtarmu game da inda rayuwa za ta iya kasancewa a cikin sararin samaniya.
3. The Gaia Space Observatory's Stellar Census
Manufar Gaia ta Hukumar Sararin Samaniya ta Turai ta kawo sauyi a iliminmu game da Milky Way tun lokacin da aka ƙaddamar da ita a shekarar 2013. Babban burin Gaia shine ƙirƙirar taswirar 3D mafi cikakken bayani na taurarinmu, ta hanyar zana taswirar matsayi, nisa, da motsin taurari sama da biliyan ɗaya tare da daidaito mara misaltuwa. A watan Disamba na 2020, Gaia ta fitar da saitin bayanai na uku, DR3, wanda ya haɗa da cikakken lura da taurari sama da biliyan 1.8.
Wannan babban bayanai yana bawa masana ilmin taurari damar yin nazarin tsarin Milky Way, abubuwan da suka tsara, da kuma juyin halittarta dalla-dalla. Bayanan Gaia sun riga sun haifar da gano sabbin tarin taurari, ingantattun samfuran juyin halittar taurari, da kuma fahimtar tarihin tasirin taurarin, gami da mu'amala da taurarin da ke makwabtaka da su kamar Manyan Girgije da Ƙananan Girgije na Magellanic.
4. The Discovery of Fast Radio Bursts (FRBs) Origins
Fashewar Rediyo Mai Sauri (FRBs) suna da ƙarfi, tsawon millisecond na raƙuman rediyo waɗanda asalinsu ya kasance masana ilmin taurari na dogon lokaci. A cikin 'yan shekarun nan, an sami ci gaba mai yawa wajen gano tushensu. An sami ci gaba a cikin 2020 lokacin da Gwajin Taswirar Intensity Hydrogen na Kanada (CHIME) da sauran na'urorin hangen nesa suka gano FRB wanda ya samo asali a cikin tauraron Milky Way ɗinmu, wanda aka haɗa shi da magnetar - wani nau'in tauraron neutron mai ƙarfin filin maganadisu.
Wannan binciken ya nuna cewa aƙalla wasu FRBs ana samar da su ta hanyar magnetars, wanda ke ba da alamu masu mahimmanci game da abin da ke faruwa a ɓoye. Binciken da ake ci gaba da yi yana da nufin fahimtar hanyoyin da ke haifar da waɗannan fashewar da kuma yuwuwar bayyana bayanai game da hanyoyin sadarwa na sararin samaniya da kuma sararin samaniya.
5. Exoplanet Exploration and Habitability
Neman gano duniyoyi masu kama da Duniya ya kai sabon matsayi tare da ci gaba a na'urorin hangen nesa na sararin samaniya da dabarun lura. Tauraron Dan Adam na Transiting Exoplanet Survey (TESS) na NASA, wanda aka ƙaddamar a shekarar 2018, da kuma Na'urar hangen nesa ta Kepler Space Telescope, wanda ya yi aiki daga 2009 zuwa 2018, sun ƙara yawan duniyoyin da aka sani da exoplanet, wanda ya bayyana duniyoyi daban-daban masu halaye masu ban sha'awa.
Wani abin lura da aka gano shi ne Proxima Centauri b, wani duniyar da ta fi girma a duniya wadda take a yankin da ake iya rayuwa a ciki na Proxima Centauri, tauraro mafi kusa da tsarin hasken rana. Binciken da aka yi kwanan nan ya nuna cewa Proxima Centauri b na iya samun yanayi mai kyau ga ruwan ruwa, wani muhimmin sinadari ga rayuwa kamar yadda muka san shi. Bugu da ƙari, TESS ta gano duniyoyi da dama da za su iya rayuwa a kusa da taurarin da ke kusa, wanda hakan ke ƙara wa begen samun alamun rayuwa bayan tsarin hasken rana.
6. The Hubble Space Telescope's Continued Contributions
An ƙaddamar da na'urar hangen nesa ta Hubble Space Telescope a shekarar 1990, kuma ta kasance ɗaya daga cikin kayan aikin kimiyya mafi inganci a tarihi. Ko bayan shekaru talatin, Hubble ya ci gaba da bayar da abubuwan lura masu ban mamaki. Abubuwan da suka fi daukar hankali a baya-bayan nan sun haɗa da gano ƙungiyar taurari mafi nisa, wacce take da nisan kimanin shekaru biliyan 13.1 na haske, da kuma cikakken bincike kan yanayin duniyar da ke waje, wanda ke ba da alamu game da yuwuwar zama a wurin.
Wani muhimmin bincike da Hubble ya yi shi ne gano tururin ruwa a cikin yanayin Europa, ɗaya daga cikin watannin Jupiter. Ana ɗaukar Europa a matsayin ɗaya daga cikin wurare mafi kyau don neman rai a cikin tsarin hasken rana, kuma kasancewar tururin ruwa yana ƙarfafa yanayin teku a ƙarƙashin ɓawon ƙanƙararsa.
7. Breakthroughs in Gravitational Wave Astronomy
Gano raƙuman ruwa masu nauyi ta hanyar Laser Interferometer Gravitational-Wave Observatory (LIGO) da haɗin gwiwar Virgo sun buɗe sabuwar taga a kan sararin samaniya. Waɗannan raƙuman ruwa a cikin lokacin sararin samaniya, waɗanda aka fara gani a 2015, ana samar da su ne ta hanyar abubuwan da suka faru kamar haɗuwar ramukan baƙi da taurarin neutron. Ci gaban da aka samu kwanan nan a fannin ilmin taurari na raƙuman ruwa ya ba da damar gano ƙarin abubuwan da suka faru na haɗuwa, yana ba da sabbin fahimta game da yanayin waɗannan abubuwa masu tsauri da kuma yanayin haɗuwarsu.
Abin lura shi ne, a shekarar 2019, LIGO da Virgo sun gano hadewar wani abu mai nauyi tsakanin tauraruwar neutron mafi karfi da aka sani da kuma ramin baki mafi sauki, wanda hakan ya kalubalanci samfuran da ake da su na juyin halitta na taurari da kuma samuwar abu mai kankanta.
Conclusion
Fannin ilmin taurari ya ci gaba da zama wurin gano abubuwa, tare da ci gaban da aka samu kwanan nan yana tura iyakokin fahimtarmu game da sararin samaniya. Daga ɗaukar hoton farko na ramin baƙi zuwa gano alamun rayuwa a Venus da kuma gano asalin fashewar rediyo mai sauri, kowane sabon bincike yana ba da wani ɓangare na wasanin gwada ilimi na sararin samaniya. Yayin da fasaha ke ci gaba da haɓaka haɗin gwiwar ƙasashen duniya, za mu iya hango ƙarin abubuwan da suka fi ban mamaki, wanda ke kusantar da mu ga amsa wasu tambayoyi masu zurfi game da matsayinmu a sararin samaniya. Neman ilimi a fannin ilmin taurari ba wai kawai yana wadatar da fahimtarmu ta kimiyya ba, har ma yana ƙarfafawa da haɗa ɗan adam a cikin neman bincika manyan abubuwan da suka wuce.
