Subj : Daily APOD Report To : All From : Ben Ritchey Date : Mon Apr 29 2019 09:46:39 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 April 29 [2] N11: Star Clouds of the LMC Image Credit: NASA [3] , ESA [4] ; Acknowledgement: Josh Lake [5] Explanation: Massive stars, abrasive winds, mountains of dust [6] , and energetic light [7] sculpt one of the largest and most picturesque regions of star formation [8] in the Local Group of Galaxies [9] . Known as N11 [10] , the region is visible on the upper right [11] of many images of its home galaxy, the Milky Way [12] neighbor known as the Large Magellanic Clouds [13] (LMC). The featured image [14] was taken for scientific purposes by the Hubble Space Telescope and reprocessed for artistry [15] by an amateur to win a Hubble's Hidden Treasures [16] competition. Although the section imaged above is known as NGC 1763 [17] , the entire N11 emission nebula is second in LMC size only to the Tarantula Nebula [18] . Compact globules of dark dust [19] housing emerging young stars are also visible around the image. A new study [20] of variable stars [21] in the LMC with Hubble [22] has helped to recalibrate the distance scale [23] of the observable universe [24] , but resulted in a slightly different scale [25] than found using [26] the pervasive cosmic microwave background [27] .
