Re: [APML] Eta Carinae

["Alson Wong" <alsonwong@earthlink.net>]

To the naked eye the Eta Carinae Nebula is not as bright as M42, but it is
much larger, at two degrees in size. The most striking aspect of a naked-eye
view of it is that its petal-like structure is plainly visible. Its size is
all the more impressive considering that it is 10,000 light-years away, six
times farther than M42.
