Star-birth region. Infrared image taken by NASA's Wide-field Infrared Survey Explorer (WISE),showing the emission nebulae NGC 7822,a star-forming cloud teeming with gas,dust and newborn stars. The blue stars at centre-right are the Berkeley 59 cluster,which are ripening out of the dust cloud from which they formed,and at just a few million years old,are young on stellar time scales. The blue dots sprinkled throughout are foreground stars in our Milky Way galaxy. Berkeley 59 and NGC 7822 lie about 3300 light years from Earth,in the constellation Cepheus | |
