Description |
(from
Mark Hanson's website) Cosmic
dust clouds and young, energetic
stars inhabit this telescopic
vista, less than 500 light-years
away toward the northern
boundary of Corona Australis,
the Southern Crown.
The
dust clouds effectively block
light from distant background
stars in the Milky Way. But the
striking complex of reflection
nebulae cataloged as NGC 6726,
6727, and IC 4812 produce a
characteristic blue color as
light from the region's young
hot stars is reflected by the
cosmic dust. The dust also
obscures from view stars still
in the process of formation. At
the left, smaller yellowish
nebula NGC 6729 bends around
young variable star R Coronae
Australis.Just below it, glowing
arcs and loops shocked by
outflows from embedded newborn
stars are identified as
Herbig-Haro objects. On the sky
this field of view spans about 1
degree. That corresponds to
almost 9 light-years at the
estimated distance of the nearby
star forming region. Over to the
left is asteroid 2263 Shaanxi
just passing through.
