Magnetic field strength map of the galactic gas and dust cloud. Field strengths rise up to 30 micro-Gauss
in this pseudo-color rendering. The seven 'magnetic cores' are circled and numbered. The gray, dashed
curve locates the cloud 'spine.' The cloud is nearly 120 light-years long, contains nearly 17,000 solar
masses of gas and dust, and is ready to form new stars.
