Qhov no galaxy yog npe Mrk 820 yog cais raws li ib tug lenticular galaxy - hom S0 ntawm lub Hubble Tuning diav rawg . Cov Hubble Tuning Fork yog siv los faib cov galaxies raws li lawv cov morphology. Elliptical galaxies zoo li du blobs saum ntuj thiab pw ntawm tus kov diav rawg.

Cov lus nug tseem yog, Dab tsi yog Hubble tuning diav rawg?

Cov Hubble Cov kab ke yog ib qho kev faib tawm morphological rau galaxies tsim los ntawm Edwin Hubble xyoo 1926. Nws yog feem ntau hu ua colloquially li Hubble tuning diav rawg daim duab vim yog cov duab nyob rau hauv uas nws yog ib txwm sawv cev.

Kuj Paub, vim li cas Hubble fork daim duab tseem ceeb? Cov Hubble kev faib tawm ntawm galaxies, kuj hu ua 'tuning diav rawg ' daim duab vim nws cov duab, cov chav kawm galaxies raws peb txoj kab tseem ceeb rau hauv: Elliptical galaxies. Kauv galaxies. Barred Kauv Galaxies.
