Cederblad 214 is one of the largest molecular cloud complexes in our Galaxy. Together with NGC 7822, it forms a large region of glowing hydrogen gas. In the centre of this region lies the young star cluster named Berkeley 59. This complex has a distance of about 3000 light-years from Earth. The central star cluster is quite young as the oldest stars formed only 5 million years ago. The principal star has a surface temperature of about 45000 K and a luminosity of over 100000 times that of the Sun, making it the hottest star within 3000 light-years from our Sun. Because of this high temperature this star generates high velocity stellar winds that formed an immense 200 light-year diameter shell of molecular gas which contacts the surrounding cold molecular cloud, supporting the generation of new stars.
