NGC 5882 is another obscure planetary nebula rarely imaged by amateur astronomers due to it being rather small and will not reveal much of it's details even with the most moderate sized instruments. so apart from the most basic information like it being in the constellation Lupus, and it being a visual magnitude of 10.85 and being very sharped edged in most images other than Hubble images. so here is something to fill in the gaps, A planetary nebula can appear similar to planets like Uranus and Neptune, they are actually gas clouds surrounding stars typically hundreds and many times thousands of light years away. Planetary nebulae form when a typical star completes fusion in its core and ejects an outer envelope of gas - usually about 10 percent of the star's initial mass. This gas shell dims in about 50,000 years - short compared to the lifetimes of stars. Therefore, although only about 1000 planetary nebula are known in our Galaxy, it is thought that most stars go through this phase. A colour representation of this Planetary Nebula will be. Green light is emitted when oxygen ions acquire electrons from the surrounding gas.
