Subj : Daily APOD Report To : All From : Ben Ritchey Date : Tue Oct 09 2018 08:37:49 Astronomy Picture of the Day Astronomy Picture of the Day Discover the cosmos! [1] Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2018 October 9 [2] NGC 1672: Barred Spiral Galaxy from Hubble Image Credit: Hubble Legacy Archive [3] , NASA [4] , ESA [5] ; Processing & Copyright: Domingo Pestana [6] & Raul Villaverde [7] Explanation: Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy [8] is thought to have a modest central bar [9] . Prominently barred spiral galaxy NGC 1672, featured here, was captured in spectacular detail in an image taken by the orbiting Hubble Space Telescope [10] . Visible are dark filamentary dust lanes [11] , young clusters [12] of bright blue stars, red emission nebulas [13] of glowing hydrogen gas, a long bright bar of stars [14] across the center, and a bright active nucleus [15] that likely houses a supermassive black hole [16] . Light takes about 60 million years to reach us from NGC 1672 [17] , which spans about 75,000 light years [18] across. NGC 1672 [19] , which appears toward the constellation of the Dolphinfish (Dorado [20] ), is being studied [21] to find out how a spiral bar contributes to star formation in a galaxy's central regions.
