Abstract

We have measured polarization of the 100 μm thermal emission from 10 points in the Orion nebula. At one of the positions the degree, 5.7%, is the largest far-infrared polarization yet discovered. Except at a position in the barlike structure to the south, the position angles of the polarization vectors are well-ordered, suggesting that a uniform magnetic field threads the cloud. We estimate the magnetic field strength to be between 0.7 and 4 mG. We discuss the relationship of the degrees of polarization to the physical conditions in the cloud.
