LL Orionis in the Orion nebula. Source
This lovely picture displays the variable star known as LL Orionis as it plows its way through the Orion nebula. The star is visible on the left side of the screen, closer to the bottom. As well as its sheer beauty, you can also notice the impressive wave preceding the star. This wave is energized interstellar gas from the surrounding nebula that is being super heated and pushed away from LL Orionis by its intense solar winds. Stars are amazing.
