  1. #SkyWatch #Astrophotography If you zoom into the right side of this image, you will see NGC7635 aka the #Bubble, an emission nebula in the constellation Cassiopeia. The Bubble is created by stellar winds from its central star, which is about 44 times the mass of our Sun. The open star cluster #M52 is in the lower left. It is 158 million years old and contains 1200 times the mass of our Sun. #StillLearning

  2. #SkyWatch #Astrophotography Yesterday's daily photo was a crop of this one which shows the #Bubble Nebula on the right and the open star cluster #M52 on the left. M52 is a large star cluster in the #Cassiopeia constellation. The central portion of the cluster shows very little interstellar matter. The current theory is that this matter was blown away by many supernova explosions early in the life of the cluster. The cluster is estimated to be more than 150 million years old. #StillLearning

  3. a #Nova just appear in Cassiopeia constellation currently brightening at magnitude 7 but could be visible to the naked eye in the next days. Easy to find because located 1/2° south to open cluster #M52 !
