Parker Solar Probe (PSP) anapanga in-situ deta yosonkhanitsira ndi kujambula zithunzi zapafupi kwambiri za Dzuwa panthawi yomwe ili pafupi kwambiri ndi perihelion mu December 2024. Zithunzizi zinakonzedwa ndikutulutsidwa posachedwapa pa 10 July 2025. Mawonedwe apafupi a kugunda kwa ma coronal mass ejection (CMEs) omwe akuchitika kunja kwa chithunzithunzi chofunika kwambiri cha dzuwa. Ma Coronal mass ejections (CMEs) ndi kuphulika kwakukulu kwa tinthu tating'onoting'ono tomwe timayendetsa kwambiri nyengo pa Dziko Lapansi ndi mumlengalenga.
Pa Disembala 24, 2024, Parker Solar Probe (PSP) idayandikira pafupi kwambiri ndi Dzuwa pamtunda wa 6.1 miliyoni km (poyerekeza, mtunda wapakati pa dziko lapansi ndi Dzuwa ndi 152 miliyoni km) pa liwiro la 692,000 km / h (liwiro lothamanga kwambiri kuposa chilichonse chopangidwa ndi munthu). Kafukufukuyu adadutsa ku corona (mlengalenga wakunja kwa Dzuwa) ndikusonkhanitsa zidziwitso mu-situ ndikujambulitsa zithunzi zapafupi kwambiri za Dzuwa pogwiritsa ntchito zida zosiyanasiyana, kuphatikiza Wide-Field Imager for Solar Probe (WISPR). Zithunzizi zidakonzedwa ndikutulutsidwa posachedwa pa 10 Julayi 2025.
Zithunzi zatsopano za WISPR za Dzuwa zikuwonetsa mawonekedwe a corona ndi mphepo yadzuwa.
Chimodzi mwazithunzi zofunika kwambiri zomwe zajambulidwa ndi kafukufukuyu ndikuwona kugunda kwa ma coronal mass ejections (CMEs), kuphulika kwakukulu kwa tinthu tambiri tomwe timayendetsa nyengo. Ma CME akawombana, njira yawo imatha kusintha, zomwe zimapangitsa kuti zikhale zovuta kudziwa komwe akupita. Kuphatikizana kwawo kungathenso kufulumizitsa tinthu tating'onoting'ono ndikusakaniza maginito, zomwe zimapangitsa kuti ma CME azitha kukhala owopsa kwa oyenda mumlengalenga ndi ma satellites mumlengalenga ndi ukadaulo pansi. Kuwona kwapafupi kwa Parker Solar Probe kumathandiza asayansi kukonzekera bwino zanyengo zapadziko lapansi ndi kupitirira apo.
Kumvetsetsa komwe kumachokera mphepo yadzuwa ndikofunikira kuti timvetsetse momwe zimakhudzira mabizinesi athu ozikidwa pamlengalenga komanso mawonekedwe amoyo ndi zomangamanga Padziko Lapansi. Zithunzi zatsopanozi zikuwonetsa bwino zomwe zimachitika ku mphepo yadzuwa itangotulutsidwa ku corona. Amawonetsa malire ofunikira pomwe mphamvu ya maginito ya Dzuwa imasinthira kuchokera kumpoto kupita kumwera, yotchedwa heliospheric current sheet.
Malingaliro apafupi amatithandizanso kuti tisiyanitse chiyambi cha mitundu iwiri ya mphepo yapang'onopang'ono ya dzuwa - Alfvénic (yokhala ndi ma switchbacks ang'onoang'ono) ndi omwe si Alfvénic (ndi kusiyana kwa maginito ake). Mphepo yosakhala ya Alfvénic imatha kubwera ndi zinthu zomwe zimatchedwa helmet streamers (malupu akulu olumikiza madera omwe tinthu tating'onoting'ono tomwe timatenthetsa kuti tithawe) pomwe mphepo ya Alfvénic imatha kuyambika pafupi ndi maenje a coronal, kapena madera amdima, ozizira pa corona.
Mphepo ya Dzuwa, mtsinje wanthawi zonse wa tinthu tating'ono tating'ono tomwe timatulutsa magetsi kuchokera ku Dzuwa lomwe limafalikira padzuwa pa liwiro lopitilira 1.6 miliyoni kmph ndi lamitundu iwiri - mwachangu komanso pang'onopang'ono. Mphepo yothamanga kwambiri yadzuwa imayendetsedwa ndi ma switchbacks (zig-zagging magnetic fields in clumps in most common in corona). Mphepo yapang'onopang'ono ya dzuwa imayenda pa theka la liwiro la mphepo yothamanga kwambiri yadzuwa (=355 km pa sekondi). Ndi yowundana kawiri komanso yosinthasintha kuposa mphepo yothamanga yadzuwa. Kutengera momwe maginito amayendera kapena kusiyanasiyana kwa maginito, mphepo zapang'onopang'ono za dzuwa zimakhala zamitundu iwiri - Alfvénic, ili ndi zosinthira zazing'ono komanso zomwe si za Alfvénic, siziwonetsa kusiyanasiyana kumeneku pamaginito ake. Ndikofunikira kuphunzira pang'onopang'ono mphepo yadzuwa chifukwa kugwirizana kwake ndi mphepo yachangu ya dzuwa kumatha kupanga mphepo yamkuntho yamphamvu kwambiri padziko lapansi.
Parker Solar Probe (PSP) imawulukira mkati mwa Dzuwa pamtunda wa makilomita 6.2 miliyoni kupita ku Dzuwa pafupi kwambiri, ndikupanga miyeso ya in-situ kuti muwone momwe mphamvu imayendera kudutsa mu corona. Solar Orbiter (SO), kumbali ina, imapanga zonse zomwe zili mu situ ndi kutalikirana pa 42 miliyoni km ku Dzuwa pafupi kwambiri. Imaphunzira ku photosphere, mlengalenga wakunja komanso kusintha kwa mphepo yadzuwa. Posachedwapa, Solar Orbiter inatenga zithunzi zoyambirira za chigawo chakumwera kwa Dzuwa kuti amvetsetse momwe Dzuwa limayendera komanso kuzungulira kwadzuwa kwake mu Marichi 2025. Onse a Parker Solar Probe (PSP) ndi Solar Orbiter (SO) akugwira ntchito mumlengalenga kuti avumbulutse magwiridwe antchito a Dzuwa ndi njira zofunika zomwe zimatsogolera kumlengalenga pa Dziko Lapansi.

 made in-situ data collection and captured closest ever images of the Sun during its last closest approach at perihelion in December 2024. These images were processed and released recently on 10 July 2025. Close –up views of collision of multiple coronal mass ejections (CMEs) taking place in outermost solar atmosphere is one of the most important images captured by the probe. Coronal mass ejections (CMEs) are large outbursts of charged particles that are a key driver of space weather effects at Earth and in space.){kind=link}
