Tag nrho cov ci ntsa iab galaxies poob rau hauv ib qho ntawm peb chav kawm dav Raws li lawv cov duab: Kauv Galaxies (~ 75%) Elliptical Galaxies (20%) Irregular Galaxies (5%)
Ntawm no, muaj pes tsawg hom galaxies muaj?
Raws li tau tham nyob rau hauv seem ntawm galaxy Kev faib tawm, Hubble pom plaub qhov sib txawv hom galaxies : elliptical, kauv, kauv barred thiab tsis xwm yeem.

Tom qab ntawd, lo lus nug yog, galaxies feem ntau faib li cas? Galaxies tuaj yeem yog cais Raws li lawv cov duab: kauv, elliptical, lossis tsis xwm yeem. Edwin Hubble, uas yog Hubble Space Telescope yog npe, devised lwm nto moo kev faib tawm tswvyim rau cov galaxies . Hubble's system suav nrog elliptical thiab kauv cov galaxies tab sis tsis suav nrog irregulars.
Ib sab saum toj no, dab tsi yog 4 hom galaxies?
Qhov kev faib tawm no yog hu ua Hubble Sequence. Nws faib cov galaxies rau hauv peb chav kawm loj nrog ob peb qhov kev hloov pauv. Niaj hnub no, galaxies tau muab faib ua plaub pawg: kauv, thaiv kauv , elliptical, thiab tsis xwm yeem.
Vim li cas thiaj muaj ntau hom galaxies?
Piav: Lub cov galaxies uas tsis muaj kev cuam tshuam rau ntau txhiab xyoo yog qhov zoo li yuav tsim cov kauv, disk zoo li tus cov galaxies . Me me cov galaxies gravitationally nyiam ib leeg thiab sib koom ua ib qho elliptical duab.
