M57: The Ring Nebula
Image Credit: NASA, ESA, Hubble Legacy Archive; Composition: Giuseppe DonatielloExplanation:
Except for the rings of Saturn
, the Ring Nebula
(M57) is probably the most famous celestial band
. Its classic appearance is understood to be due to our own perspective, though. The recent mapping
of the expanding
, based in part on this clear Hubble image
,indicates that the nebula is a relatively dense, donut-like ring wrapped around the middle of a (American) football-shaped
cloud of glowing gas. The view from planet Earth looks down the long axis of the football, face-on to the ring. 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 the dying, once sun-like star
, now a tiny pinprick of light seen at the nebula’s center. Intense ultraviolet
light from the hot central star ionizes atoms
in the gas. The Ring Nebula
is about one light-year
across and 2,000 light-years away.
