Subj : Daily APOD Report To : All From : Ben Ritchey Date : Tue Jan 15 2019 06:51:54 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 January 15 [2] The Heart and Soul Nebulas Image Credit & Copyright: Mario Zauner [3] Explanation: Is the heart and soul of our Galaxy located in Cassiopeia [4] ? Possibly not, but that is where two bright emission nebulas [5] nicknamed Heart and Soul [6] can be found. The Heart Nebula [7] , officially dubbed IC 1805 [8] and visible in the featured image on the bottom right, has a shape reminiscent of a classical heart symbol [9] . The Soul Nebula [10] is officially designated IC 1871 and is visible on the upper left. Both nebulas [11] shine brightly in the red light of energized [12] hydrogen [13] . Also shown in this three-color montage is light emitted from sulfur [14] , shown in yellow, and oxygen [15] , shown in blue. Several young open clusters [16] of stars [17] are visible near the nebula centers. Light [18] takes about 6,000 years to reach us from these nebulas [19] , which together span roughly 300 light years [20] . Studies [21] of stars and clusters like those found in the Heart [22] and Soul [23] Nebulas have focused on how massive stars [24] form and how they affect their environment [25] .
