NGC 2440 is a planetary nebula that resides along the star rich central plane of the Milky Way in the constellation Puppis. It is quite bright for a planetary nebula and glows at magnitude 11. It is another interesting example of what stars look like in their death throes. Some stars end up exploding like a firecracker and are called a nova. Other stars do not quite explode but rather puff up like popcorn and are called a planetary nebula…. though they really have nothing planetary about them. HD62166 is one of the hottest white dwarf stars known and is the central star that remains after the main sequence star cast of its outer layer of gas.
