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.
This narrow band image adopts
a typical false-color mapping of
the atomic emission, showing hydrogen emission
in green hues, sulfur as red and oxygen as blue.
At an estimated distance of 6,000 light-years, the region shown
is about 80 light-years across.
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.
