Description

NGC 7822 and Cederblad 214 (Sh2-171) form a large molecular cloud and star forming region in the constellation of Cepheus. This is the center of the "Cosmic Question Mark". NGC 7822 forms the faint northern arch at the top of the image, while Cederblad 214 is the brighter nebula towards the bottom. This field of view is filled with a multitude of young stars born from the hydrogen gas in the cloud. These young stars also form several clusters within the nebula. The cluster Berkeley 59 is located at the heart of Cederblad 214, while NGC 7762 is towards the upper right of the ring.
Within Cederblad 214 is one of the hottest known stars in our stellar neighborhood. With a temperature of almost 45,000 degrees Kelvin, BD+66 1673 is over 100,000 times more luminous than our own Sun. Also contained within Cederblad 214 are numerous Bok globules - areas of of condensing gas from which young protostars are created.
