Subj : Daily APOD Report To : All From : Ben Ritchey Date : Tue Sep 11 2018 07:56:48 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 September 11 [2] Milky Way over Troll's Tongue Image Credit & Copyright: Ruslan Merzlyakov [3] (RMS Photography [4] ) Explanation: You have to take a long hike [5] to see the Troll's Tongue -- ten hours over rocky terrain. And in this case, it took three trips to capture the landform [6] below a clear night sky. Trolltunga [7] itself is a picturesque rock protrusion [8] extending about 700 meters over mountainous cliffs near Lake Ringedalsvatnet [9] in Norway [10] . The overhang [11] is made of billion-year-old Precambrian [12] bedrock [13] that was carved out by glaciers during an ice-age about 10,000 years ago. The featured picture [14] is a composite of two exposures, a 15-second image of the foreground [15] Earth [16] followed 40 minutes later by an 87-second exposure of the background [17] sky. Thousands of discernable stars dot the backdrop starscape [18] in addition to billions of unresolved stars in the nearly vertical band of our Milky Way Galaxy [19] .
