Westerhout 1 is a prominent radio source located in the constellation of Cassiopeia. It is classified as a bright H II region, which is a cloud of gas and dust where new stars are forming. This region is notable for its intense emission of radio waves, making it an important object of study in astrophysics. Discovered by astronomer Jan Westerhout in the 1950s, Westerhout 1 is part of a larger complex of star-forming regions. Its study helps scientists understand the processes of star formation and the dynamics of interstellar matter in our galaxy, the Milky Way.
