Halo of a spiral galaxy
WebThe Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,590 light-years), but only about 1,000 light years thick at the spiral arms (more at the bulge). ... WebAug 8, 2006 · M88 is our first definite spiral galaxy (type Sb), and a beauty it is! Medium-size telescopes show a fairly bright oval halo surrounding a moderately large and somewhat brighter oval core. Higher powers best show the very small nucleus. These three components of the visual impression are common to ordinary spiral galaxies.
