Subj : Daily APOD Report To : All From : Ben Ritchey Date : Wed Feb 27 2019 04:00:01 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. 2019 February 27 [2] Magnetic Orion Image Credit & Copyright: NASA [3] , SOFIA [4] , D. Chuss [5] et al. & ESO [6] , M. McCaughrean [7] et al. Explanation: Can magnetism affect how stars form? Recent analysis [8] of Orion data from the HAWC+ instrument [9] on the airborne [10] SOFIA observatory [11] indicate that, at times, it can. HAWC+ is able to measure the polarization [12] of far- infrared light [13] which can reveal the alignment of dust grains [14] by expansive ambient magnetic fields [15] . In the featured image [16] , these magnetic fields are shown as curvy lines superposed on an infrared image [17] of the Orion Nebula [18] taken by a Very Large [19] Telescope [20] in Chile [21] . Orion's Kleinmann-Low Nebula [22] is visible slightly to the upper right of the image center, while bright stars of the Trapezium cluster [23] are visible just to the lower left of center. The Orion Nebula [24] at about l300 light years [25] distant is the nearest major star formation [26] region to the Sun [27] .
