			NGC 281 is a busy workshop of star formation.  
Prominent features include a small 
open cluster of stars, 
a diffuse red-glowing 
emission nebula, large lanes of obscuring 
gas and 
dust, and dense knots 
of dust and gas in which stars may still be forming.  
The open cluster 
of stars IC 1590 visible around the center 
has formed only in the last few million years.  
The brightest member of this cluster is actually a 
multiple-star system 
shining light that helps ionize the nebula's gas, 
causing the red glow visible throughout.  
The lanes of dust 
visible left of center are likely homes
of future star formation.  
Particularly striking in the 
above photograph are the dark 
Bok globules 
visible against the bright nebula.  
The entire 
NGC 281 system lies about 10 thousand light years distant.
