Mountains of Creation
Explanation:
This fantastic skyscape
lies at the eastern edge of giant
stellar nursery W5, about 7,000 light-years away in the constellation
Cassiopeia.
An infrared view from the
Spitzer
Space Telescope,
it features interstellar clouds of cold gas and dust
sculpted by winds and radiation from a hot, massive star
outside the picture (just above and to the right).
Still swaddled within the cosmic clouds,
newborn stars
are revealed
by Spitzer's penetrating gaze, their
formation also
triggered
by the massive star.
Fittingly dubbed "Mountains of Creation", these
interstellar
clouds are about 10 times the size of the analogous
Pillars of Creation in M16, made famous in a
1995 Hubble Space Telescope view.
W5 is also known as IC 1848 and
together with IC 1805 it is part of
a complex
region popularly dubbed the
Heart and
Soul Nebulae.
The Spitzer image spans about 70 light-years at the distance of
W5.
