Hornet Nebula (PK 164+31.1)
This is a planetary nebula visible in the northern part of the constellation Lynx.
It was discovered in 1939 by Rebecca B. Jones and Richard Emberson on a photographic plate acquired with the 40 cm diameter refracting telescope at Oak Ridge Observatory.
It is best observed from the northern hemisphere, with the best time for observation in the evening sky being from November to May, when it is very high above the horizon.
Like many other planetary nebulae, its structure and shape are due to the expansion of a shell of gas ejected from a dying star; at its centre is a DQ-class white dwarf, whose ultraviolet radiation excites and illuminates the gas envelope, which is composed mainly of hydrogen, giving it its characteristic red colour, while the blue areas are due to the presence of oxygen.
