It was discovered by astronomer John Herschel in

ASTRONOMY PICTURE OF THE DAY: NGC 7822. Credit & Copyright: Neil Fleming. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. The image maps emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The atomic emission is powered by the energetic radiation from the hot stars, whose powerful winds and radiation also sculpt and erode the denser pillar shapes. Stars could still be forming inside the pillars by gravitational collapse, but as the pillars are eroded away, any forming stars will ultimately be cut-off from their reservoir of star stuff. This field spans around 60 light-years.

WORK OF ART: Studies of the Foetus in the Womb are two-coloured annotated sketches by Leonardo da Vinci made in around 1511. Da Vinci studied human embryology with the help of anatomist Marcantonio della Torre and saw the foetus within a cadaver. The studies were initially bequeathed to Francesco Melzi. In c. 1582–90 they were bought from his heirs by Pompeo Leoni, and by 1630 they belonged to Thomas Howard, 2nd Earl of Arundel. Since 1690 the studies have been housed in the Royal Collection, United Kingdom.
