NGC 7822 in Cepheus

8d0e1afbaa86ffb1fa7fd6c20c0bf8e2.1824x0_q100_watermarkNGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800-1000 pc distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45000 K and a luminosity ~100000 times that of the Sun. The star is one of the primary sources illuminating the nebula and shaping the complex’s famed pillars of creation-type formations, the elephant trunks.

Region NGC 7822 in Cepheus

9b81e2640edc1f5bde97452edcbdcdae.1824x0_q100_watermark_watermark_opacity-15_watermark_position-1_watermark_text-Copyright Michael MillerNGC 7822 is a large and expansive region of emission nebulosity on the border between Cepheus and Cassiopeia. NGC 7822 represents a region of active star formation and includes the young open cluster Berkeley 59 at the western tip of the nebula with many of the member stars estimated to be only a few million years-old. NGC 7822 lies at a distance of 2,600 to 3,300 light-years away and spans approximately 30 light-years and 90 arc-minutes in diameter (equivalent to three full moons) and another 20 arc-minutes high. The nebula is believed to be illuminated by one of the brightest stars closest to the sun known, namely BD+66 1673, and whose surface temperature is approximately 45,000 degrees Kelvin.
