231-838
December 14, 2009 · ESA/Hubble · 231-838, Messier 42 , Orion Nebula
One of 42 new proplyds discovered in the Orion Nebula, 231-838 is one of the bright proplyds that lies relatively close to the nebula’s brightest star, Theta 1 Orionis C. Resembling a boomerang, this proplyd is surrounded by a shock wave that is caused by stellar wind from the massive Theta 1 Orionis C interacting with gas in the nebula.
