Explanation:
What's happened to the Ring Nebula?
The familiar Ring that can be seen with a
small back-yard telescope takes on a new
look when viewed in dim light.
The above recently-released, false-color image taken by the giant
Subaru Telescope
shows details of
giant halos of diffuse gas that are seen to
envelop the entire structure.
The Ring Nebula, also known as
M57,
is an elongated
planetary nebula, a type of nebula that is created
when a Sun-like star evolves to throw off its outer atmosphere
and becomes a
white dwarf.
The Ring Nebula is about 2000 light-years away,
and the main ring
spans about one light-year.
The origin and future evolution of the
Ring Nebula's outer halos is still being investigated.
