Infrared Ring Nebula
Explanation:
The classic appearance of the popular
Ring Nebula
(aka M57) is understood to be due to perspective -
our view from planet Earth looks down the center
of a roughly barrel-shaped cloud of gas.
But graceful looping structures are seen to extend
even beyond the Ring Nebula's familiar central regions in this
false-color infrared image
from the
Spitzer Space Telescope
.
Of course in this well-studied example of a
planetary
nebula
, the glowing material
does not
come from planets.
Instead, the gaseous shroud represents outer layers expelled
from a dying, sun-like star.
By chance, spiral galaxy IC 1296 is also visible in the upper
right of this Spitzer view toward the
constellation
Lyra
.
The central ring of the Ring Nebula is about one light-year
across and 2,000 light-years away.
However, galaxy IC 1296
much bigger
and hence farther
away ... about 200 million light-years distant.
