This map shows the effect of an enormous star, nearly one-hundred thousand times the brightness of the Sun, on star forming dust in a small slice of our galaxy. Taken from grad student Lauren Cashman and Prof. Dan Clemens' recent paper, the gray background shows dust levels measured by the WISE satellite, while red lines trace out polarization, a measure of the magnetic field winding through the dust cloud (measured by Mimir on the Perkins telescope). The dot in top right indicates the location of the super bright run-away O star Zeta Ophiuchi, whose intense ultraviolet emission is squashing the cloud's dust and magnetic field.
