[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 12 [2] A Cosmic Rose: The Rosette Nebula in Monoceros Image Credit & Copyright [3] : Jean Dean [4] Explanation: The Rosette Nebula, NGC 2237, is not the only cosmic cloud of gas and dust to evoke [5] the imagery [6] of flowers [7] , but it is the most famous. At the edge of a large molecular cloud [8] in Monoceros some 5,000 light years away, the petals of this cosmic rose are actually a stellar nursery. The lovely, symmetric shape is sculpted by the winds [9] and radiation [10] from its central cluster of hot young, O-type stars [11] . Stars in the energetic cluster [12] , cataloged as NGC 2244 [13] , are only a few million years young, while the central cavity in the Rosette Nebula, is about 50 light-years [14] in diameter. The nebula can be seen with a small telescope toward the constellation of Monoceros [15] , the Unicorn. This natural appearing telescopic portrait of the Rosette Nebula was made using broadband and narrowband filters, because sometimes roses aren't red [16] .
