IC 4628: The Prawn Nebula
Explanation: South of
Antares, in the tail of the
nebula-rich constellation Scorpius, lies emission nebula
IC 4628. Nearby hot, massive stars, millions of years young,
radiate the nebula with invisible ultraviolet light, stripping electrons from atoms. The
electrons eventually recombine with the atoms to produce the visible
nebular glow, dominated by the red emission of
hydrogen. At an estimated distance of 6,000 light-years,
the region shown is about 250 light-years across,
spanning an area equivalent to four full moons
on the sky. The nebula is also
cataloged as Gum 56 for Australian astronomer
Colin Stanley Gum, but seafood-loving astronomers might
know this cosmic cloud as the
Prawn Nebula.

https://en.wikipedia.org/wiki/Shrimp_on_the_barbie wrote:
<<"Shrimp on the barbie" is an often-quoted phrase that originated in a series of television advertisements by the Australian Tourism Commission starring Paul Hogan from 1984 through to 1990. The actual quote spoken by Hogan is "I'll slip an extra shrimp on the barbie for you." "Barbie" is Australian slang for barbecue; Australians, however, invariably use the word prawn rather than shrimp. Because the commercial was commissioned for broadcast in the United States, the change was made to limit audience confusion.
The advertisement pre-dated Hogan's popularity in the 1986 film Crocodile Dundee and thus were not initially seen as celebrity advertisements in America, as he was relatively unknown in the United States. The campaign was launched during the National Football Conference Championship Game in January 1984. Before the campaign, Australia was approximately number 78 on the "most desired" vacation destination list for Americans, but became number 7 three months after the launch, and soon became number 1 or 2 on Americans' "dream vacation" list, remaining in that position for most of the next two decades.
Prawns are a popular traditional Christmas seafood in Australia. However, crustaceans such as shrimp and prawns are less common, on average, in the Australian cuisine than in the United States. In the late 1980s, annual per capita consumption of shrimp stood at 1.3 kg in the United States, second only to Japan.>>

I'm not normally a fan of mapped false colour images but I think this is really nice!
The nebula is also catalogued as RCW 116.

The colors may be false, but the mapping isn't!

It's a false image color mapping! Lotsa turquoise and
chartreuse.
Schkoll!
