LL Ori and the Orion Nebula
This
esthetic close-up of cosmic clouds and stellar winds features LL
Orionis, interacting with the Orion Nebula flow. Adrift in Orion's
stellar nursery and still in its formative years, variable star LL
Orionis produces a wind more energetic than the wind from our own
middle-aged Sun. As the fast stellar wind runs into slow moving gas a
shock front is formed, analogous to the bow wave of a boat moving
through water or a plane traveling at supersonic speed.

The
small, arcing, graceful structure just above and left of center is LL
Ori's cosmic bow shock, measuring about half a light-year across. The
slower gas is flowing away from the Orion Nebula's hot central star
cluster, the Trapezium, located off the upper left corner of the
picture. In three dimensions, LL Ori's wrap-around shock front is shaped
like a bowl that appears brightest when viewed along the "bottom" edge.
The beautiful picture is part of a large mosaic view of the complex
stellar nursery in Orion, filled with a myriad of fluid shapes
associated with star formation.
