NGC 281: Cluster, Clouds, and Globules
Explanation:
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 below the center are likely homes
of future
star formation.
Particularly striking in the
above photograph are the dark
Bok globules
visible against the bright nebula.
Stars are surely forming there right now.
The entire
NGC 281 system lies about 10 thousand
light years distant.
