The image of the nebula, which is better known by unappetizing nickname - the "Rotten Egg Nebula
" - was released by NASA and the European Space Agency (ESA) Friday.
Now sweep 3.0[degrees] east from Lambda ([lambda]) Cygni to the protoplanetary Egg Nebula (PK 80-6 1).
The Egg Nebula is easily visible as a little fuzzy spot even in my 130-mm scope at 63x.
The Egg Nebula's common name was bestowed by Mike Merrill due its oval appearance on the photographic prints of the National Geographic Society-Palomar Observatory Sky Survey (S&T: January 1975, page 21).
The star and its shells resemble an egg white around a yolky centre, leading the astronomers to nickname the object the 'Fried Egg Nebula
The Egg Nebula
(above, left), in particular, provides astronomers with a look at a star in the act of shedding its atmosphere.
The article gives the early history of the now-famous Egg Nebula
- the first-discovered proto-planetary nebula.
It will then look much like the Egg Nebula
, pictured at right.
In this article you can follow an evolutionary sequence, from the Egg Nebula (a proto-planetary) below to the Butterfly Nebula (an extremely young planetary) on page 31 and finally to Hubble 5 (a true planetary nebula) on the facing page.
Merrill named it the Egg Nebula, based on its appearance on Palomar Observatory Sky Survey plates.
The most famous protoplanetary is the Egg Nebula
in Cygnus, shown on the previous page (May issue, page 12).
CRL2688, also known as the Egg Nebula
, lies some 3,000 light-years away in Cygnus.
