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.
