NGC_2236 is a bright open star cluster located in the constellation of Monoceros, also known as the Unicorn. It is approximately 2,000 light-years away from Earth and contains around 50 stars. The cluster is estimated to be about 2 million years old, making it relatively young in astronomical terms. Discovered by John Herschel in 1831, NGC_2236 is notable for its loose structure and the presence of several blue supergiant stars. It is often studied for insights into stellar evolution and the dynamics of star clusters, contributing to our understanding of the life cycles of stars.
