NGC7822 The devils head - Ördög fej

HUN: Az NGC7822 a Cepheus csillagképben látható csillagkeletkezési terület. Az emissziós köd részét Sharpless 171, a benne található nyílt halmazt Berkeley 59 katalógus számon jelölik, de a Cederblad 214 jelzés is erre a területre utal. A köd érdekessége, hogy itt található az 1 kpc környezeten belüli legforróbb ismert csillag, melynek hőmérséklete 45 ezer kelvin és fényessége 100 ezerszerese a Napénak. Ennek a csillagnak az erodáló hatása alakította ki a szóban forgó ködösség alakját. A képen látható oszlop szerű képződmények is ennek a csillagnak az irányába mutatnak.

The complex also includes one of the hottest stars discovered within 1 kpc of the Sun. Its surface temperature is nearly 45,000 Kelvin and its luminosity about 100,000 times that of the Sun. This is the star which shapes the form of the complex. The pillar like object in the nebula shows the direction it the star.
