[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 November 12 [2] The Lagoon Nebula is Stars, Gas, and Dust Image Credit & Copyright: Nelson Ortega [3] Explanation: The majestic Lagoon Nebula [4] is filled with hot gas and the home for many young stars. Spanning 100 light years [5] across while lying only about 5000 light years distant, the Lagoon Nebula [6] is so big and bright that it can be seen [7] without a telescope [8] toward the constellation [9] of the Archer (Sagittarius [10] ). Many bright stars are visible from NGC 6530 [11] , an open cluster [12] that formed in the nebula [13] only several million years ago. The greater nebula, also known as M8 [14] and NGC 6523 [15] , is named "Lagoon" for the band of dust seen to the left of the open cluster's center. The featured image was taken in three colors with details are brought out by light emitted by Hydrogen [16] Star formation [17] continues in the Lagoon Nebula [18] as witnessed by the many dark dust-laden globules [19] that exist there.
