Gamma, peb lub hnub qub rau brightness, ib tug dawb ntsias, yog lub ntiaj teb ntawm ib tug deb ntawm 188 lub teeb xyoo. Delta muaj tib tus qauv raws li qhov Alpha. Nyob rau hauv nws muaj pes tsawg leeg ob ntsias - daj thiab txiv kab ntxwv. Qhov kev ncua deb ntawm peb ntiaj chaw thiab cov hnub qub yog yam tsawg kawg 35 lub teeb xyoo.

Muab Kauv Galaxy M33

Constellation yooj yim coj thiab muaj nyob rau hauv nws cov pom ib thaj tsam, tab sis yog tsis yog tus brightest, tab sis ib tug haum zoo-paub kauv galaxy M33, uas yog ib hom Sc thiab yog ib feem ntawm ib pab pawg neeg ntawm lub zos galaxies. Nws dog dig vague, muaj ntau ntau yam loj heev kaj xiav hnub qub thiab lub hnub qub nyob nrog ua ceev nyob rau hauv nws cov centre. Qhov kev ncua deb ntawm lub hnub mus rau lub kauv galaxy M33 yog sib npaug zos rau peb vam teeb xyoo tam sim ntawd. Nyob rau hauv no galaxy tam sim no qhib ntau tshaj 110 nce mus nce los hnub qub.

Qhov loj cov khoom ntawm no cheeb tsam ntawm lub ntuj yog Galaxy Andromeda, Kab lig ntuj thiab Galaxy daim duab peb sab, kuj hu ua M33 los yog NGC598.

Cov loj kauv galaxies muaj lawv tus kheej sub-pawg neeg ntawm cov galaxies. Feem ntau ntawm lawv yog txuam nrog rau cov "niam txiv" loj loj gravitational rog. Galaxy daim duab peb sab honorable ibyam thib peb (tom qab lub Andromeda thiab cov Kab lig ntuj) raws li ib feem ntawm lub zos pab pawg neeg cov galaxies. Nws txoj kab uas hla yog hais txog 50-55,6 txhiab lub teeb-xyoo.

Nyob rau hauv lub galaxy ntawm lub daim duab peb sab sab dub qhov M33 X-7, ib tug txaus loj loj. cosmic cev huab hwm coj ntau dua li lub hnub 16 lub sij hawm. Qhov no yog ib tug ntawm cov loj tshaj plaws dub qhov, nrog rau cov kev zam ntawm tsuas supermassive qhov ze txaus los ntawm peb.

Nyob rau hauv lub constellation ntawm lub daim duab peb sab muaj xws li lwm yam galactic systems, lawv yog tsawg ci, thiab lawv cov nqi tsis pub tshaj lub thib kaum ib stellar. Qhov loj tshaj plaws ntawm lawv - lub kauv galaxy NGC925. Qhov kev ncua deb ntawm peb hnub rau NGC925 yog 46 lab teeb-xyoo. Qhov no yog nyob deb txaus, tab sis ua tsaug rau cov high-powered telescopes, astronomers kawm qhov chaw thiab cim cov khoom ntawm lub ntug nyob rau hauv no ib feem ntawm lub ntuj.
