The entire 30 Doradus complex has been
an active star-forming region for 25 million years, and it is currently unknown
how much longer this region can continue creating new stars. Smaller systems
that merge into larger ones could help to explain the origin of some of the
largest known star clusters. The Hubble observations, made with the Wide Field
Camera 3, were taken Oct. 20-27, 2009. The blue color is light from the
hottest, most massive stars; the green from the glow of oxygen; and the red
from fluorescing hydrogen.
