Variable star

Its story

θ¹ Orionis is the centrepiece of the Trapezium, the cluster of young stars lighting the heart of the Great Orion Nebula, one of the closest and most photographed stellar nurseries. A hot variable O-type star, she ionises the surrounding gas and lends it the pinkish glow that makes the nebula famous in any amateur telescope.
