SbWhat type of galaxy is NCG 1317? a. E5 b. SBa c. S0 d. Sa
- Hubble's galaxy classification diagram (the "tuning fork") O suggests the existence of black holes O shows how galaxies evolve from one form to another O relates galaxies according to their shapes, but not according to any evolutionary status O explains active galactic nuclei EGOLooking for ___ hr38. Many RR Lyrae stars are found in open clusters in the plane of the galaxy. True False
- Indicate whether the following statements are true or false. (Select T-True, F-False. If the first is T and the rest F, enterTFFFFF). A) The three main classifications of galaxies are elliptical, spiral and prime.B) The mass of a spiral galaxy can be found from its rotational velocity. The greater the rotation, the greater the mass.C) Galaxies sometimes collide with each other.D) It wasn't until the 1920s that we knew the Milky Way was only one of many galaxies.E) Most galaxies are elliptical.F) The shorter the pulsation period of a Cepheid variable star, the more luminous it is.The Sun is located in a. the center of the Milky Way Galaxy b. the bulge of the Milky Way Galaxy c. the halo of the Milky Way Galaxy d. the disk of the Milky Way GalaxySuppose you have obtained spectra of several galaxies and have measured the observed wavelength of the H-Alpha line (rest wavelength = 656.3 nm) to be Galaxy 1: 658.1 nm.
