Explanation:
Carved by a bright
young star in
Orion's dusty molecular clouds, NGC 2023 is often
overlooked in favor of the nearby
dramatic silhouette of the Horsehead Nebula.
In
its own right
it is seen as a beautiful star forming emission
and reflection nebula though, a mere 1500 light-years distant.
Surprisingly colorful and complex filaments are detailed in
this rare NGC 2023 portrait.
Scattered points of emission are also from the region's
Herbig-Haro
objects,
associated with the energetic jets from newborn stars.
The sharp telescopic view spans about 10 light-years at the estimated
distance of NGC 2023.
Off the right edge of the frame lies the more familiar
cosmic Horsehead.
