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.

Region IC 1396

172babf392ed3d75b6301ddf67a7bf45.1824x0_q100_watermark
IC 1396  is ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth.
Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within the obscuring cosmic dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees.

NGC 7023 is actually the cluster within the nebula, LBN 487, and the nebula is lit by a magnitude +7 star, SAO 19158. It shines at magnitude +6.8. It is located near theMira-type variable star T Cephei, and near the bright magnitude +3.23 variable star Beta Cephei (Alphirk). It lies 1,300 light-years away and is six light-years across.

Sharpless 132: The Lion Nebula in Cepheus

Sharpless 132 is a faint emission nebula at the Cepheus/Lacerta border, it measures 42 x 30 arcminutes. It lies about a degree southeast of ε Cep. It can be glimpsed visually, but that takes a rich-field refractor and very dark skies. Sh2-132 lies in the field of the Cepheus OB1 association. It is related to Cep OB1, whose distance is given as 10,000 to 12,000 light-years, thus it is located in the Perseus arm of our Galaxy, and measures more than 250 light years in extent. Some photographers call it “The Lion Nebula” due to its shape (head upper left, tail to the right, four legs below). It features a conspicuous dark lane in the “head” section.

Sharpless 171 in Cepheus

1d360e8cd3ecdd9e8cbde3e4db3007b3.1824x0_q100_watermark
Cosmic pillars of cold molecular gas and clouds of dark dust lie within Sharpless 171, a star-forming region some 3,000 light-years away in the royal constellation Cepheus. This tantalizing false-color skyscape spans about 20 light-years across the nebula’s bright central region. It also highlights the pervasive glow of emission from atomic gas using narrowband filters and a color palette made popular in Hubble Space Telescope images. Powering the nebular glow are the young, hot stars of a newly formed cluster, Berkeley 59. Of course, this star-forming region is entry number 171 in the famous 1959 catalog of emission nebulae compiled by astronomer Stewart Sharpless.

Reflection nebula VdB 152 in Cepheus

Described as a “dusty curtain” or “ghostly apparition”, mysterious reflection nebula VdB 152 really is very faint. Far from your neighborhood on this Halloween Night, the cosmic phantom is nearly 1,400 light-years away. Also catalogued as Ced 201, it lies along the northern Milky Way in the royal constellation Cepheus. Near the edge of a large molecular cloud, pockets of interstellar dust in the region block light from background stars or scatter light from the embedded bright star giving parts of the nebula a characteristic blue color.

IC1396: the Elephant’s Trunk nebula

The Elephant’s Trunk nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. The piece of the nebula shown here is the dark, dense globule IC 1396A; it is commonly called the Elephant’s Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star that is just to the west of IC 1396A. (In the Figure above, the massive star is just to the left of the edge of the image.) The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star’s harsh ultraviolet rays.

NGC 7822 in constellation of Cepheus

35b1e507745edf1ecd75b4301a831d64.1824x0_q100_watermark
NGC 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.
