Dust Pillar of the Carina Nebula
Explanation:
Inside the head of this interstellar monster is a star that is slowly destroying it.
The monster, actually an inanimate pillar of
gas
and
dust
, measures over a
light year
in length.
The star, not itself visible through the opaque dust,
is bursting out partly by ejecting
energetic beams of particles
.
Similar epic battles are being waged all over the star-forming
Carina Nebula
.
The stars will win in the end, destroying their
pillars of creation
over the next 100,000 years, and resulting in a new
open cluster
of stars.
The pink dots are newly formed stars that have already been freed from their birth monster.
The
above image
is only a small part of a
highly detailed panoramic mosaic
of the
Carina Nebula
taken by the
Hubble Space Telescope
and released last week.
The technical name for the stellar jets are
Herbig-Haro objects
.
How a star creates
Herbig-Haro jet
s is an ongoing
topic of research
, but it likely involves an
accretion disk
swirling around a central star.
A second impressive
Herbig-Haro jet
is visible across the bottom of
a larger image
