Astronomers ntawm European Southern Observatory tau txheeb xyuas qhov loj tshaj plaws stellar dub qhov puas tau pom nyob rau hauv Milky Way. Lub qhov dub tau pom nyob rau hauv cov ntaub ntawv los ntawm European Space Agency lub hom phiaj Gaia. Lub qhov dub, hu ua Gaia BH3, muaj 33 npaug ntawm lub hnub. Cov ntawv no tau luam tawm rau hnub tim 16 hauv phau ntawv xov xwm Astronomy thiab Astrophysics.
Stellar dub qhov yog tsim los ntawm lub cev qhuav dej ntawm cov hnub qub loj, thiab yav dhau los qhov dub qhov pom nyob rau hauv Milky Way tau kwv yees li 10 npaug ntawm lub hnub. Txawm tias Cygnus X-1, qhov thib ob loj tshaj plaws paub lub hnub qub dub qhov hauv Milky Way, tsuas yog 21 hnub ci.
Zoo kawg nkaus, lub qhov dub no nyob ze rau lub ntiaj teb, tsuas yog 2,000 lub teeb xyoo deb. Nyob rau hauv lub constellation Aquila, nws yog qhov thib ob ze tshaj plaws paub lub qhov dub rau lub ntiaj teb.
Astronomers tau pom zoo ib yam li cov dub qhov loj heev sab nraum Milky Way thiab xav tias lawv yuav tau tsim los ntawm lub cev qhuav dej ntawm lub hnub qub thiab muaj ob peb yam hnyav dua hydrogen thiab helium nyob rau hauv lawv cov tshuaj muaj pes tsawg leeg. Astronomers xav tias cov hnub qub hlau tsis zoo no poob qis thaum lawv lub neej, yog li lawv muaj cov khoom siv ntxiv tom qab lawv tuag, tsim lub qhov dub loj. Tab sis cov pov thawj txuas cov hnub qub hlau tsis zoo ncaj qha mus rau qhov dub loj heev txog tam sim no tsis muaj.
Cov khub ntawm cov hnub qub zoo li muaj cov ntsiab lus zoo sib xws, uas txhais tau hais tias Gaia BH3 tus khub tuav cov ntsiab lus tseem ceeb ntawm lub cev qhuav dej los tsim qhov tshwj xeeb no lub hnub qub dub. Cov ntaub ntawv qhia tias Gaia BH3 tus khub yog lub hnub qub hlau-tsis zoo, qhia tias lub hnub qub uas ploj mus ua Gaia BH3 kuj yog hlau-tsis zoo, raws li tau hais tseg.
Niaj hnub no, kuv xav qhia rau koj txog cov khoom siv kho mob tub rog ntawm peb lub tuam txhab, hu ua Tub Rog Tub Rog Bandage. Cov khoom no muaj ntau lub tswv yim tsim qauv, nws yog qhov zoo tshaj plaws nyob rau hauv kev cawm thiab kev ua tub rog, tsis tshua muaj nqi, tag nrho cov ntaub qhwv yog cov ntaub qhwv zoo heev thiab muaj zog, ib sab yog txuas nrog cov ntaub qhwv tsis muaj menyuam, cov khoom tuaj yeem cia cov neeg ua haujlwm pabcuam thawj zaug hauv cov kev xav tau tshaj plaws los ua haujlwm sai, tswj tau thiab ua haujlwm pabcuam thawj zaug. Xav txog qhov tshwj xeeb ntawm cov ntaub qhwv ntsej muag, peb kuj tau tsim cov yas clasps ntawm cov ntaub qhwv ntsej kom yooj yim kho cov ntaub qhwv, kom tsis txhob raug mob thib ob los ntawm qhov poob ntawm cov ntaub qhwv, los yog muab lub zog tshwj xeeb ntawm lub qhov txhab kom ua tiav lub hom phiaj. hemostasis. Peb kuj tsim cov ntaub qhwv kom loj hlob kom lawv tuaj yeem siv los dai caj npab, ruaj ntseg splints, thiab lwm yam haujlwm. Cov ntaub qhwv uas tsis muaj nplaum nplaum hauv cov ntaub qhwv tau ua tib zoo kom tsis muaj menyuam thiab tuaj yeem siv ncaj qha.
