2.2 Apod

IN this picturing you are seeing a dusty and shape less emission of the region Sh2-155, also know as the Cave Nebula. Data was taken through narrowband filters tracks glow of ionized sulfur, hydrogen, and oxygen atoms in red, green, and blue. This nebula is about 2400 light years away. The picture lies on the plane of the milky way toward the northern constellation of Cepheus. Studies show that it has formed a massive Cepheus B Molecular cloud, young starts of Cepheus OB 3 association. The bright rim of ionized interstellar gas The bright rim energized by radiation from the hot stars, dominated by the bright star just above picture center. The ionization fronts are likely triggering collapsing cores and new star formation within. The cosmic cave is over 10 light-years across.
