NGC 7822: Stars and Dust Pillars in Infrared “NGC 7822 lies at the edge of a giant molecular cloud toward the northern constellation Cepheus, a glowing star forming region that lies about 3,000 light-years away. The atomic emission of light by the nebula’s gas is powered by energetic radiation from the hot stars, whose powerful winds and light also sculpt and erode the denser pillar shapes.” Image Credit: NASA, ESA, ESO -- source link
