The constellation of Orion features one of the largest emission nebulae in the sky: Barnard’s loop (discovered by E. E. Barnard around 1900), which was probably formed by a series of supernova explosions some 3 million years ago. Also visible are Great Orion Nebula (M42, overexposed) and the Horsehead Nebula.
