Explanation: It is one of the brightest planetary nebulae on the sky
-- what should it be named? First discovered in 1878, nebula NGC 7027 can be seen toward the
constellation of
the Swan (Cygnus) with a standard backyard
telescope. Partly because it appears there as only an indistinct spot, it is
rarely referred to with a moniker. When imaged with the Earth-orbiting Hubble Space Telescope,
however, great details are revealed. Studying Hubble images of NGC 7027 have led to
the understanding that
it is a planetary
nebula that began expanding about 600 years ago, and that the cloud
of gas and dust is unusually massive as it appears to contain about three times
the mass of our Sun. Pictured
above in assigned
colors, the resolved, layered, and dust-laced features of NGC 7027 might remind
sky
enthusiasts of a familiar icon that could be the basis for an informal name.
Please feel free to make
suggestions -- some suggestions are being recorded, for example, in an online APOD
discussion forum.
