NGC 1672: Barred Spiral Galaxy from Hubble Image Credit: [3]Hubble Legacy Archive, [4]NASA, [5]ESA; Processing & Copyright: [6]Daniel Nobre Explanation: Many spiral galaxies have bars across their centers. Even our own [7]Milky Way Galaxy is thought to have a [8]modest central bar. Prominently barred spiral galaxy NGC 1672, [9]featured here, was captured in spectacular detail in an image taken by the orbiting [10]Hubble Space Telescope. Visible are dark filamentary [11]dust lanes, young [12]clusters of bright blue stars, red [13]emission nebulas of glowing hydrogen gas, a long bright bar of [14]stars across the center, and a bright [15]active nucleus that likely houses a supermassive [16]black hole. Light takes about 60 million years to reach us from [17]NGC 1672, which spans about 75,000 [18]light years across. [19]NGC 1672, which appears toward the constellation of the Dolphinfish ([20]Dorado), has [21]been studied to find out how a spiral bar contributes to star formation in a galaxy's central regions.
