Sh2-213, also known as the "Drunken Dragon Nebula," is a bright emission nebula located in the constellation of Cassiopeia. It is part of a larger complex of star-forming regions and is notable for its intricate structure and vibrant colors, which are produced by ionized gas and dust. This nebula is approximately 2,500 light-years away from Earth and spans about 30 light-years across. It is home to several young, hot stars that contribute to the ionization of the surrounding gas, making it a fascinating area for astronomers studying stellar formation and the dynamics of interstellar matter.
